New Technology of Optical Fiber Communication
New Technology of Optical Fiber Communication
1. Concept of WDMWDM (wavelength division multiplexing) technology is a technology that transmits multiple wavelength optical signals in one optical fiber at the same time.The basic principle of optical wavelength division multiplexing (WDM) is that the optical signals of different wavelengths are combined (multiplexed) at the transmitting end and coupled to the same optical fiber on the optical cable line for transmission, and the optical signals of combined wavelengths are separated (demultiplexed) at the receiving end for further processing, and the original signals are recovered and sent to different terminals. Therefore, this technology is called optical wavelength division multiplexing, Referred to as optical wavelength division multiplexing technology.How wide is the bandwidth of optical fiber?As shown in Fig. 7.6, there are two low loss transmission windows in the optical fiber: the wavelength is 1.31 μ m(1.25~1.35 μ m) Window, corresponding bandwidth (| Δ f|=|- Δλ c/ λ 2|, λ and Δλ Are the central wavelength and corresponding band width respectively, C is the speed of light in vacuum) is 17700 GHz; Wavelength 1.55 μ m(1.50~1.60 μ m) The corresponding bandwidth is 12500 GHz.When the two windows are combined, the total bandwidth exceeds 30thz. If the channel frequency interval is 10GHz, ideally, one fiber can accommodate 3000 channels.At present, some optical devices and technologies are not very mature, so it is difficult to realize optical frequency division multiplexing (OFDM) with dense optical channels. In this case, wavelength division multiplexing with small channel spacing in the same window is called dense wavelength division multiplexing (DWDM).At present, the system is an optical communication system composed of 8, 16 or more wavelengths on a pair of optical fibers (single optical fiber can also be used) in the 1550nm wavelength range, in which the spacing between each wavelength is 1.6nm, 0.8nm or less, which corresponds to the band width of 200ghz, 100GHz or narrower.WDM, DWDM and OFDM are not much different in essenceIn the past, technicians used to use WDM and DWDM to distinguish between 1310 / 1550nm simple multiplexing and 1550nm intensive multiplexing, but at present, DWDM technology is used in telecom applications.Since the multiplexing of 1310 / 1550nm exceeds the gain range of EDFA and is only used in some special occasions, WDM is often used to replace DWDM.WDM technology is of great significance for network upgrading, developing broadband services (such as CATV, HDTV and IP over WDM), fully tapping the potential of optical fiber bandwidth and realizing ultra-high speed optical fiber communication. Especially WDM and EDFA have a strong attraction to modern information network.At present, "erbium doped fiber amplifier (EDFA) dense wavelength division multiplexing (WDM) non-zero dispersion optical fiber (NZDSF, i.e. G.655 fiber) photonic integration (PIC)" is becoming the main technical direction of long-distance high-speed optical fiber communication lines in the world.If all optical fiber transmission links in an area are upgraded to WDM transmission, we can set an optical cross connection device (OXC) for cross connection of optical signals in wavelength units or an optical add drop multiplexer (OADM) for optical uplink and downlink at the intersection (node) of these WDM links, and a new optical layer will be formed on the physical layer originally composed of optical fiber links.In this optical layer, the wavelength channels in adjacent optical fiber links can be connected to form an optical path across multiple OXC and OADM to complete end-to-end information transmission, and this optical path can be flexibly and dynamically established and released according to needs, which is the eye-catching and new generation WDM all-optical network.2. Basic form of WDM systemOptical wavelength division multiplexer and demultiplexer are the key components of WDM technology. The device that combines signals of different wavelengths and outputs them through an optical fiber is called multiplexer (also known as multiplexer).On the contrary, the device that decomposes the multi wavelength signal sent by the same transmission fiber into each wavelength and outputs it respectively is called demultiplexer (also known as demultiplexer).In principle, this device is reciprocal (bidirectional reversible), that is, as long as the output and input of the demultiplexer are used in reverse, it is a multiplexer.Therefore, the multiplexer and demultiplexer are the same (unless there are special requirements).The basic composition of WDM system mainly includes the following two forms: dual fiber unidirectional transmission and single fiber bidirectional transmission.(1) Dual fiber unidirectional transmission.Unidirectional WDM transmission means that all optical paths are transmitted in the same direction on one optical fiber at the same time.As shown in Figure 7.7, dimmed signals with different wavelengths containing various information will be sent at the transmitter λ 1, λ 2,…, λ N is combined by optical multiplexers and transmitted unidirectionally in one optical fiber.Since the signals are carried through different light wavelengths, they will not be confused with each other.At the receiving end, signals of different wavelengths are separated by optical demultiplexer to complete the task of multi-channel optical signal transmission.The principle of transmission through another optical fiber in the opposite direction is the same.(2) Single fiber bidirectional transmission. Bidirectional WDM transmission means that the optical path transmits to two different directions on one optical fiber at the same time. As shown in Figure 7.8, the wavelengths used are separated from each other to realize bidirectional full duplex communication.Several key system factors must be considered in the design and application of bidirectional WDM system:For example, in order to suppress multi-channel interference (MPI), we must pay attention to the influence of light reflection, isolation between bidirectional paths, type and value of crosstalk, power level value and mutual dependence of two-way transmission, optical monitoring channel (OSC) transmission and automatic power shutdown, and use bidirectional fiber amplifier at the same time.Therefore, the development and application of bidirectional WDM system are relatively demanding, but compared with unidirectional WDM system, bidirectional WDM system can reduce the number of optical fibers and line amplifiers.In addition, by setting an optical add drop multiplexer (OADM) or optical cross connector (OXC) in the middle, the optical signals of each wavelength can be merged and shunted, and the wavelength add / drop and route allocation can be realized. In this way, the inserted or separated signals can be reasonably arranged according to the traffic distribution of optical fiber communication lines and optical networks.3. Performance parameters of optical wavelength division multiplexerOptical wavelength division multiplexer is an important part of wavelength division multiplexing system. In order to ensure the performance of wavelength division multiplexing system, the basic requirements for wavelength division multiplexer are:• low insertion loss• high isolation• flat in band and steep out of band insertion loss• good temperature stability• multiple channels• small size, etc(1) Insertion loss insertion loss refers to the additional loss caused by the addition of optical wavelength division multiplexer / demultiplexer, which is defined as the ratio of optical power between the input and output ports of the passive device, i.e(7.1)Where Pi is the optical power sent into the input port; Po is the optical power received from the output port.(2) Crosstalk suppression system crosstalk refers to the influence degree that the signals of other channels are coupled into a channel and degrade the transmission quality of the channel. Sometimes, this degree can also be expressed by isolation. For demultiplexer(7.2)Where Pi is the wavelength λ I is the input optical power of the optical signal, and PIJ is the wavelength λ The optical signal of I is connected in series to the wavelength of λ Optical power of channel J.(3) Return loss return loss refers to the ratio of the optical power returned from the input port of the passive device to the input optical power, i.e(7.3)Where PJ is the optical power sent into the input port, and PR is the return optical power received from the same input port.(4) Reflection coefficient reflection coefficient refers to the ratio of reflected light power PR to incident light power PJ at a given port of WDM device, i.e(7.4)(5) Working wavelength range working wavelength range refers to the wavelength range in which WDM devices can work according to the specified performance requirements( λ Min to λ max)。(6) Channel width channel width refers to the wavelength interval between light sources to avoid crosstalk.(7) Polarization dependent loss (PDL) refers to the maximum change of insertion loss caused by the change of polarization state.

Basic Knowledge of Cable Installation
Whether the cable is installed correctly or not is directly related to our personal safety, so it is very important to learn the correct cable installation method. First of all, we need to understand the precautions for cable installation: first, when the mining cable is placed in parallel with the heating pipeline, it shall be connected with a distance of 2m, and when interleaved, it shall be connected with a distance of 0.5m. Second, when the cable is placed in parallel or interleaved with other pipelines, it shall be connected with a distance of 0.5m. 3、 When the cable is directly buried, the direct burial depth of 1-35kV cable shall not be less than 0.7m. IV. when the cables of 10kV and below are placed in parallel, the clear distance between each other shall not be less than 0.1M, 10-35kV shall not be less than 0.25m, and the distance during interleaving shall not be less than 0.5m.

A. When placing the cable terminal, the semi-conductive barrier layer must be stripped off. The insulation shall not be damaged during operation. Knife marks and the environment with high and low resistance shall be prevented. If necessary, it shall be polished with sandpaper; The end of the barrier shall be flat, and the graphite layer (carbon particles) shall be broken and cleaned. B. The copper barrier and steel armor at the end of plastic insulated cable must be well grounded, and this criterion should also be observed for short routes to prevent electromotive force at the end of steel armor during three-phase unbalanced operation, even ignition and burning of sheath. Tinned braided copper wire shall be adopted for grounding outgoing line. Soldering iron shall be used for soldering when it is adjacent to cable copper strip, and blowtorch shall not be used for sealing welding to avoid burning insulation. C. The three-phase copper barrier shall be connected with the ground wire respectively.

They are really just meant to see if it's cut or not. Network switches will keep statistics on lines which may indicate some type of deterioration1. how to recover a lost security key using a lexsys router?If you have a machine connected by cable you are in luck. If not, connect your laptop via Ethernet cable to one of the numbered ports on the back of the router. Using the browser of your choice put in 192.168.1.1 in the address field. Unless you have changed it, that is the address of the linksys router. This will bring up a web page from the router. If it asks for an ID/password if you have changed it you will need it to go further. If you have not changed it then the ID is left blank and the password is "admin". Go to Wireless tab, select Security tab and the encryption code (password) will pop up. If is is all stars click on the box to show letters. Now, if you have just forgotten all of the stuff that has changed you will need to reset the router. There is a little button on the back, recessed a little. With the power connected, using a ballpoint pen tip, push in the button and hold it for 30 seconds. While still holding the button, remove the power plug from the back of the router and keep the button pushed in for another 30 seconds. Then, with the button still pushed in plug the power back in, keeping the button depressed for a last 30 seconds. Then release the button. The router will restart with factory settings. After the reset the router SSID will be "linksys" and it will have no security (password) required. You need to access the router now and set it up from scratch.2. cable tv is too expensive?great place to go when bored - work.

What Is The Main difference Between Cat 5e Ethernet cable and Cat 6 Cable Ethernet Cable?Let's say you want to play Warcraft with your buddies. A high-speed internet is what you would require for an uninterrupted gaming experience. You can either go for a Wi-Fi networking or a wired network. No doubt, Wi-Fi provides a convenient way to connect the computers at home without any unnecessary hassle of wires. But then, it is also slow and unreliable at times. A wired network, on the contrary, will enable a high-speed network for online gaming, video streaming, file sharing, and much more. Before opting for a completely wired network for your home, you should know about the different cables available in the market. Knowing which Ethernet cable to use can enhance your gaming experience. There are different kinds of network cords that can solve your purpose. The most popular ones include Cat5, Cat5e Cable and Cat 6 Cable. Each of them has its own specific qualities. However, you must select the one that best fits your purpose. All of these cables might look similar from outside but they are internally different. If you look at the text printed on the cable, you'll get to know what type it is. Here is a list of what all you need to know to select the perfect cable for your home network. Cat5: "Old and Slow"Cat5 is oldest of all the network cables. It is made to handle 10/100 Mbps speed, which means it is comparatively slow and less responsive. These cables are old and obsolete. You probably won't find them at a store but if you have an old modem, you might search for one. Cat5e: "Improved and Faster"It is the most used network cable. Cat5e Cable is better at keeping signals in different circuits or channels from interfering with each other. A much-improved Cat5e is made to handle 1000Mb speed, so it is faster than Cat 5 and provides a better networking experience. It is, currently, the most commonly used cable in new installations.Cat6: "Even Faster"Next to Cat5e is a Cat6 cable. It is way faster and much improved. This networking cord is made to support 10 Gigabit speed of Ethernet, which is huge. You probably don't have this high-speed network at your home. This cable would not make much of a difference with the speeds that we get at present. But if you are going for a new one, you might as well go for Cat6 as it is the best of the lot. What Is The Main difference Between Cat 5e Ethernet cable and Cat 6 Cable Ethernet Cable?
Working Principle of Cable Fault Tester
Working Principle of Cable Fault Tester
Working principle of power cable fault tester consists of three main parts: power cable fault tester host, cable fault locator and cable path tester. The host of the cable fault tester is used to measure the nature and total length of the cable fault and the approximate position between the cable fault point and the test end. The cable fault locator determines the exact location of the cable fault point based on the approximate location of the cable fault point determined by the host of the cable fault tester. For buried cables with unknown direction, a pathfinder shall be used to determine the underground direction of the cable. The basic method of power cable fault test is to apply high-voltage pulse to the fault power cable to produce breakdown at the cable fault point. When the cable fault breakdown point discharges, it generates electromagnetic wave and sound at the same time. The working principle of the application of arc reflection method (secondary pulse method) in cable fault location: firstly, a high voltage pulse with a certain voltage level and energy is applied to the faulty cable at the test end of the cable to make the high resistance fault point of the cable break down and burn arc. At the same time, add the low-voltage pulse for measurement at the test end. When the measurement pulse reaches the high resistance fault point of the cable, it encounters an arc and reflects on the surface of the arc. When arcing, the high resistance fault becomes an instantaneous short-circuit fault, and the low-voltage measurement pulse will change obviously in impedance characteristics, so that the waveform of flashover measurement becomes a low-voltage pulse short-circuit waveform, making the waveform discrimination particularly simple and clear. This is what we call the "secondary pulse method". The received low-voltage pulse reflection waveform is equivalent to the waveform of a wire core completely short circuited to ground. Superimpose the low-voltage pulse waveform obtained when releasing the high-voltage pulse and when not releasing the high-voltage pulse. The two waveforms will have a divergence point, which is the reflected waveform point of the fault point. This method combines low-voltage pulse method with high-voltage flashover technology, which makes it easier for testers to judge the location of fault point. Compared with the traditional test methods, the advantage of the secondary pulse method is to simplify the complex waveform in the impulse high-voltage flashover method into the simplest low-voltage pulse short-circuit fault waveform, so the interpretation is very simple and the fault distance can be accurately calibrated. The triple pulse method adopts the double impact method to prolong the arc burning time and stabilize the arc, which can easily locate the high resistance fault and flashover fault. The triple pulse method has advanced technology, simple operation, clear waveform and fast and accurate positioning. At present, it has become the mainstream positioning method of high resistance fault and flashover fault. The third pulse method is an upgrade of the second pulse method. The method is to first measure the reflected waveform of the low-voltage pulse without breaking through the fault point of the measured cable, then impact the fault point of the cable with the high-voltage pulse to generate an arc, trigger the medium voltage pulse when the arc voltage drops to a certain value to stabilize and prolong the arc time, and then send the low-voltage pulse, Thus, the reflected waveform of the fault point is obtained. After the superposition of the two waveforms, it can also be found that the divergence point is the corresponding position of the fault point. Because the medium voltage pulse is used to stabilize and prolong the arc time, it is easier to obtain the fault point waveform than the secondary pulse method. Compared with the secondary pulse method, the triple pulse method does not need to select the synchronization time of arc burning, and the operation is also more simple.
Buried Cable Fault Tester
Buried Cable Fault Tester
With the continuous strengthening of China's national strength, the development of power system is getting better and better. Cables have been widely used, and have high security because of their own characteristics. However, because most power cables are buried underground, it is inconvenient for people to determine the fault location. If the fault can not be eliminated in time, the resulting loss will be very serious. Underground cable fault tester introduces the underground cable fault tester, which is used to locate underground buried utilities. The basic form is divided into two parts, - one is the transmitter and the other is the receiver. The transmitter part is used to sense the signal to the pipeline or cable, and then the rod or receiver is used to locate the signal generated by the line. Can you find electricity, cable TV, telephone, water or gas pipes and tracer lines? Yes, any underground utility with metal structure and linear and preferably grounded along the path or end point can be located by any so-called cable fault locator. Did you find plastic (or any non-metallic tools)? No, the utility must have metal linearity for the signal of the locator to be transmitted downward. However, if a tracer line is buried next to or included in a non-metallic utility, the metal is metallic and can be located. Sometimes, a metal linear device (such as a plumber's snake or an electronic fish belt) can be inserted into the interior of a non-metallic pipe and positioned by applying a signal to the inserted device. What is the best choice of cable fault locator when there are many utility cables working underground and nearby? Multi frequency mode is preferred. By selecting frequency and power adjustments, this provides a way to isolate utilities from other facilities and reduce interference. Function introduction of underground cable fault tester the underground cable fault tester covers what is necessary to locate and track the path of wires, cables, pipes and conduits, whether buried underground or behind the wall. When you want to dig underground and avoid crossing buried utilities, this section contains a combination of locators and tracers to enable users to identify and mark routes and locations, saving thousands of dollars in maintenance costs. The function of cable fault tester (also known as cable fault tester) is the same as that of most buried utility locators. The transmitter is used to supply power to metal wires (cables or pipes) at a certain frequency by directly conductive connection to metal wires. Connect a single conductor of the transmitter to the pipe. The other - conductor is grounded perpendicular to the line and as far away from the line as possible. This forms a closed circuit that allows the current to flow. The current flowing through the pipe generates a magnetic field, which forms a columnar area around the pipe and represents a signal. A magnetic field is produced by an electric current rather than a voltage. The capacitance increases with the increase of conductor surface area. Therefore, the larger the conductor or pipe, the shorter the signal transmission distance. Buried cable fault detection is quite common in the actual power work, and the cable fault types and causes are also diverse. Therefore, there are enough advanced detection equipment to escort the power. Once a fault occurs, first analyze the fault types and causes, and then determine the fault location according to the fault state, Finally, the fault is handled to ensure the normal operation of the power supply system.
Instructions for Use of Cable Fault Tester
Instructions for Use of Cable Fault Tester
When using the cable fault tester, we should first look at some simple waveform diagrams to analyze different cable faults, and then find out the fault points through the corresponding methods. The following is our simple analysis and description. 1. Test the low resistance grounding, short circuit and open circuit faults of the cable with the low voltage pulse method. A. no other auxiliary equipment is needed at this time. A clip wire is directly connected to the input and output interface of the cable fault location host. Clamp the red clamp of the clamp wire on the faulty phase core wire of the faulty cable, and the Black clamp on the sheath ground wire of the cable. B. Start the power switch of the instrument, the screen saver picture will appear on the screen, and click to enter the interface automatically. At this time, the default state of the instrument is "low voltage pulse method". The use method shall be selected according to the type and length of the tested cable on site and the fault nature preliminarily judged. When it is set to "low voltage pulse method", wave velocity measurement can also be carried out on this interface, and historical files can be opened to view previous test results. C. After setting the equipment parameters, click the "sampling" button, and the instrument will automatically send out test pulses. This interface will display the (open circuit) full-length waveform of the cable (as shown in Figure 5) or the low resistance grounding (short circuit) fault waveform (as shown in Figure 6). If the waveform is not good, the operator shall adjust the "median" and "amplitude" and observe the collected echo until the operator thinks that the amplitude and position of the echo are suitable for analysis and positioning. Basic information such as instrument parameter setting is also displayed at the bottom of the screen. During operation, pay attention to the operation status at the bottom of the screen. D. Waveform positioning reading distance. It is easy to judge the distance of low-voltage pulse, as long as the cursor is positioned to the starting point of transmitted and reflected waves respectively. E. When "saving", the test results need to be retained or reserved for comparison. The "saving" function in the instrument should be used to save the measured waveform in the instrument database. If the tester thinks it is necessary to save the test results, he can click "save" and operate according to the prompt in the submenu. 2. The high resistance leakage fault (including high resistance flashover fault) of the cable is tested by the impact high voltage flashover method. The instrument can test the high resistance leakage fault of the cable by the impact high voltage flashover method. Impulse high voltage flashover method is a popular traditional detection method in China. Many users are used to this method. The external circuit is relatively simple, but the waveform analysis is more difficult. Only on the basis of a large number of tests and some experience can we master it skillfully, but it is still an effective test method. Connect the current sampler attached to the instrument with the host with the signal wire and place it next to the grounding wire between the cable and the high-voltage equipment. As long as the output voltage of the impulse high voltage generator is high enough, the fault point will be broken down under the impulse of this impulse high voltage, and the radio wave reflection will be generated in the cable. The current sampler transmits the induced reflected wave obtained from the current signal on the ground wire through magnetic coupling to the cable fault location host for a / D sampling and data processing, and displays the collected waveform on the screen for fault distance analysis. After the cable type and sampling frequency are determined, you can click the "sampling" button to wait for sampling. Once the high-voltage generator has impulse high-voltage flashover, the instrument will automatically carry out data acquisition and waveform display. The red waveform at the top of the screen is the waveform after local amplification, and the blue waveform at the bottom is the full picture of the test waveform. When the ideal waveform is collected, the "waveform scaling" and displacement and moving cursor can be operated to calibrate the fault distance. The operation method is consistent with the low-voltage pulse method. 3. Wave velocity measurement cables produced by different manufacturers, although the models are the same, the differences in process and medium formula will lead to the differences in radio wave propagation velocity. If the average wave propagation speed given by the instrument is directly used, it will cause a certain test error. In order to test the fault distance more accurately, it is often necessary to recheck (test) the radio wave propagation speed of the cable.

The tracker looks at the signal strength of each TV through its satellite dish and sends live data about how much signal is being received by each TV and what channels are being received by each TV."This data is sent over the Internet so that it can be analyzed by any computer with an Internet connection."Section topic: Firewall SoftwareIntroduction: "We like firewalls because they help us keep ourWe are living in a world where everything is connected and information flows across the internet. However, it’s not always easy to talk to people when you are thirsty for information.This is where cable tracker software can help. It allows people to send messages to different websites and applications at the same time, regardless of their location or devices.
Matters Needing Attention During Cable Fault Tester Test
Matters Needing Attention During Cable Fault Tester Test
The cable fault tester is used to test the open circuit, short circuit, grounding, low resistance, high resistance flashover and high resistance leakage faults of power cables, as well as the open circuit and short circuit fault test cables of coaxial communication cables and local telephones. You can also test cable path, burial depth and radio wave velocity measurement, verify cable length, etc., and establish cable files for daily maintenance management. The cable fault tester uses the time domain reflection principle to send a series of electrical pulses to the tested cable, receives the reflected pulses caused by the change of cable impedance, and then represents them according to the propagation speed of the cable. The characteristic inflection points of the electric wave and two reflected waves in the cable. Time, the distance from the fault point to the test end can be measured. Precautions when using: 1. During the pulse method test, please pay attention to get rid of all equipment in the office and measure on the outside line. 2. When using the flashover method for testing, be sure to set the trigger working mode switch to the "flashover" position. 3. When using direct flash method or flash method for testing, please pay attention to personal safety and equipment safety. Be sure to connect the ground wire. 4. After the flashover test, cut off the power supply, unplug the connecting line between the instrument and the high-voltage test equipment, and then release the charge stored in the high-voltage capacitor and cable. During discharge, current limiting resistor R shall be added to limit the discharge current to discharge slowly. After the voltage on the capacitor decreases, the resistance in the discharge circuit is directly zero. Equipment or personal accident. 5. During the direct flash test, be sure to monitor the leakage current of the fault. If the current increases suddenly and there is no fault flashover, immediately reduce the test voltage and use the flash test. The smoothness and power transmission of the cable fault tester system depend on the normal operation of the cable line. Once the line is blocked, communication and power supply will be interrupted. If the fault can not be found and eliminated in time, it will cause huge economic losses and adverse social impact. Therefore, maintenance personnel should pay attention to ensure the normal operation of cable fault tester during work.
