Three Common Methods for OTDR Optical Fiber Testing
Three Common Methods for OTDR Optical Fiber Testing
Optical fiber communication is a communication mode with optical wave as carrier and optical fiber as transmission medium. Optical fiber communication has become the main means of information transmission and the cornerstone of "information highway" because of its long transmission distance, large information capacity and high communication quality. Optical fiber testing technology is the most extensive and basic special technology in the field of optical fiber applications. OTDR is the main instrument in the field of optical fiber testing technology. It is widely used in the maintenance and construction of optical fiber lines. It can measure the length of optical fiber, transmission attenuation of optical fiber, joint attenuation and fault location. OTDR has the advantages of short test time, fast test speed and high test accuracy.1. Two basic formulas supporting OTDR TechnologyOTDR (optical time domain reflectometer) is a high-tech and high-precision photoelectric integrated instrument made by using Rayleigh scattering and Fresnel reflection when optical pulse is transmitted in optical fiber. The semiconductor light source (LED or LD) outputs light pulses modulated by the driving circuit, which are injected into the tested optical cable line through the directional optical coupler and movable connector to become incident light pulses.When the incident light pulse is transmitted in the line, Rayleigh scattered light and Fresnel reflected light will be generated along the way. Most of the Rayleigh scattered light will be refracted into the cladding and attenuated. The back Rayleigh scattered light opposite to the propagation direction of the light pulse will be transmitted to the light inlet port of the line along the optical fiber, and will be transmitted to the photodetector through directional coupling shunt and converted into electrical signals, After low-noise amplification and digital averaging, the processed electrical signal is scanned synchronously with the trigger signal emitted from the back of the light source and becomes a reflected light pulse on the oscilloscope.The returned useful information is measured by the OTDR detector, and they are regarded as time or curve segments at different positions in the measured optical fiber. According to the time from transmitting signal to returning signal, and then determine the speed of light in quartz material, the distance (fiber length) l (unit: m) can be calculated, as shown in formula (1).In formula (1), n is the average refractive index and â–³ t is the transmission delay. The attenuation a (unit: dB / km) can be calculated by using the power level corresponding to the incident light pulse and the reflected light pulse and the length of the measured optical fiber, as shown in formula (2):2. Five parameter settings to ensure OTDR accuracy2.1 test wavelength selectionSince OTDR serves optical fiber communication, the test wavelength shall be selected before optical fiber test, and only 1310 nm or 1550 nm shall be selected for single-mode optical fiber. Since the influence of 1550 nm wavelength on the bending loss of optical fiber is much more sensitive than 1310 nm wavelength, 1550 nm wavelength is generally used to test the whole process optical fiber backscattering signal curve of an optical cable or an optical fiber transmission link, whether it is optical cable line construction, optical cable line maintenance or experiment and teaching.The shapes of the test curves at 1310nm and 1550nm are the same, and the measured fiber connector loss values are basically the same. If no problem is found in the 1550 nm wavelength test, the 1310 nm wavelength test is certainly no problem.If the 1550 nm wavelength is selected for testing, it is easy to find out whether there is excessive bending in the whole process of the optical fiber. If a large loss step is found somewhere on the curve, retest with 1310 nm wavelength. If the loss step disappears at 1310 nm wavelength, it indicates that there is excessive bending at this place, which needs to be further found and eliminated. If the loss step is also large at 1310 nm wavelength, there may be other problems in the optical fiber, which need to be found and eliminated. In the test of single-mode optical fiber line, 1550 nm wavelength should be selected as far as possible, so the test effect will be better.2.2 optical fiber refractive index selectionThe refractive index of the single-mode optical fiber used now is basically in the range of 1.4600 1.4800, which should be accurately selected according to the actual value provided by the optical cable or optical fiber manufacturer. For G.652 single-mode fiber, if 1310 nm wavelength is used in actual test, the refractive index is generally 1.4680; If 1550 nm wavelength is used, the refractive index is generally 1.468 5. Incorrect selection of refractive index will affect the test length.In equation (1), if the refractive index error is 0.001, an error of about 35 m will be generated in the relay section of 50000 M. Small mistakes in optical cable maintenance and troubleshooting will bring obvious errors, which must be paid enough attention during testing.2.3 selection of test pulse widthIf the set light pulse width is too wide, strong Fresnel reflection will be generated, which will increase the blind area. Although the narrow test light pulse has a small blind area, the test light pulse is too narrow, the power must be too weak, the corresponding backscattering signal is also weak, the backscattering signal curve will fluctuate, and the test error is large. The set optical pulse width shall not only ensure that there is no strong blind spot effect, but also ensure that the backscattering signal curve has sufficient resolution and can see each point along the optical fiber.Generally, an appropriate test pulse width is selected according to the length of the measured optical fiber, and an optimal value is determined after one or two trials. When the distance of the measured optical fiber is short (less than 5000 m), the blind area can be less than 10 m; When the distance of the measured optical fiber is long (less than 50000 m), the blind area can be less than 200 m; When the distance of the measured optical fiber is very long (less than 2500 000 m), the blind area can be up to more than 2000 m.In the single disk test, the blind area can be less than 10 m by properly selecting the optical pulse width (50 nm). If the average value is obtained through two-way test or multiple tests, the impact of blind area will be less.2.4 selection of test rangeThe range of OTDR refers to the maximum distance that the abscissa of OTDR can reach. During the test, the measuring range shall be selected according to the length of the measured optical fiber, and it is better that the measuring range is 1.5 times the length of the measured optical fiber. If the range selection is too small, it can not be seen comprehensively on the display screen of the optical time domain reflectometer; When the range selection is too large, the abscissa compression on the display screen of the optical time domain reflectometer can not be seen clearly.According to the practical experience of engineers and technicians, the selection of test range can make the backscatter curve account for about 70% of the OTDR display screen, whether it is length test or loss test, better direct viewing effect and accurate test results can be obtained.In the test of optical fiber communication system, the link length is hundreds to thousands of kilometers, the relay section length is 40 60 km, and the single optical cable length is 2 4km. Good test results can be obtained by selecting the range of OTDR.2.5 selection of averaging timeBecause the backscattered light signal is extremely weak, the method of multiple statistical average is generally used to improve the signal-to-noise ratio. OTDR test curve samples the reflected signal after each output pulse, and averages the multiple samples to eliminate random events. The longer the averaging time is, the closer the noise level is to the minimum value, and the larger the dynamic range is. The dynamic range obtained with an average time of 3 min is 0.8 dB higher than that obtained with an average time of 1 min.Generally speaking, the longer the averaging time, the higher the test accuracy. In order to improve the test speed and shorten the overall test time, the test time can be selected within 0.5 3 min.In the connection test of optical fiber communication, satisfactory results can be obtained by selecting 1.5 min (90 s).3 three common methods of OTDR testingWhen OTDR tests optical cables and optical fibers, the test occasions include factory test of optical cables and optical fibers, construction test of optical cables and optical fibers, maintenance test and regular test of optical cables and optical fibers. The test connection of OTDR is shown in Figure 1.The test connection method is: OTDR - optical fiber connector - the first optical cable - the second optical cable - the nth optical cable, and the terminal is not connected to any equipment. According to the actual test work, there are three main methods:3.1 OTDR backward test methodThis method is mainly used to monitor the optical cable connection. The optical cable connection must be equipped with a special optical fiber fusion machine and optical time domain reflectometer (OTDR). After welding a fiber core, the welding machine will generally give the estimated attenuation value of this contact. This method of testing has three advantages:(1) OTDR is fixed, omitting the vehicles and a lot of manpower and material resources required for instrument transfer;(2) The test point is selected in the place where there is mains power without gasoline generator;(3) The test points are fixed to reduce the stripping of optical cables.At the same time, this method also has two disadvantages:(1) Due to distance and terrain constraints, it is sometimes impossible to ensure smooth communication;(2) With the continuous increase of connection distance, the test range and accuracy of OTDR are limited.At present, there are generally three methods to solve these problems:â‘ The use of mobile phones in the city and suburbs can keep the testers and successors in touch at any time, facilitate organization and coordination, and improve work efficiency.â‘¡ Contact by telephone. Make sure to connect one optical fiber (such as blue optical fiber unit and red optical fiber) to the optical telephone as the connecting line. Of course, the last optical fiber used for communication cannot be monitored because it cannot be contacted during fusion and fiber winding. Even so, the possibility of problems will be greatly reduced (if it is a 24 core optical cable, the probability of problems will be reduced to less than 1 / 24 of the original).â‘¢ When the optical cable connection reaches a relay distance, the OTDR moves forward.The test practice shows that these monitoring methods are effective to ensure quality and reduce rework.3.2 OTDR forward one-way test methodOTDR is tested at the first joint point in the optical fiber connection direction, and construction vehicles are used to transfer the test instruments and testers in advance. Using this method for monitoring, the test point and connection point always have only one disc of optical cable length, the attenuation accuracy of the test joint is high, and it is convenient for communication. At present, the length of one optical cable is about 2 3 km. In general terrain, communication can be ensured by using walkie talkie. If the optical cable has a corrugated steel strip protective layer, you can also use the magnet telephone to contact.The disadvantages of this test method are also obvious. Moving OTDR to each test point is labor-consuming and time-consuming, which is not conducive to the protection of instruments; The test points are also limited by the terrain, especially when the line is far away from the highway and the terrain is complex. Portable OTDR is selected for monitoring. The short-range test does not require high dynamic range of the instrument, and the small 0tdr has small volume, light weight and convenient movement, which can greatly reduce the workload of testers and improve the test speed and work efficiency.3.3 OTDR forward two-way test methodThe OTDR position is still the same as the "forward one-way" monitoring, but two optical fibers are respectively short circuited at the beginning of the connection direction to form a loop. This method can not only meet the optical fiber test of relay section, but also monitor the optical fiber connection. When testing the optical fiber in the relay section, the incident light pulse, reflected light pulse, joint point, fracture point, fault point and attenuation distribution curve can be clearly seen on the display screen of the optical time domain reflectometer. The OTDR test event type and display are shown in Figure 2, which can provide convenience for optical cable maintenance.When monitoring optical fiber connection, due to the increase of loopback point, the bidirectional value of connection loss can be measured on OTDR. The advantage of this method is that it can accurately evaluate the quality of the joint.Due to the test principle and optical fiber structure, there will be false gain and false large attenuation in one-way monitoring with OTDR. For an optical fiber connector, the mathematical average of attenuation values in two directions can accurately reflect its real attenuation value. For example, the attenuation of a connector measured from a to B is 0.16 dB, and that measured from B to a is -0.12 dB. In fact, the attenuation of this connector is [0.16 (- 0.12)] / 2 = 0.02 dB.4 ConclusionAs the main instrument of optical fiber communication,

There were a lot of features to implement onto the screwdriver that would be difficult to fit onto a handheld device so as I was sketching, I tried to consider space as a constraint. Another thing I noticed was that there was a big difference in readability between putting numbers side-by-side and one top of the other.PrototypeTo build my prototype I used cardboard and tape. I made the prototype larger than the actual size it would be so that I could clearly display the features and test the interface functionality with a user. Here is what the prototype looks like:AnalysisTo test this prototype, I sat down with a participant and asked them to screw in and unscrew a screw at a specified setting while vocalizing their thought process. The user was able to complete the task but there were a few features that were unclear.Features that were unclear to the user:Used the Phillips instead of a flat head on the screwThought the unscrew/screw switch was to activate the screw driverSuggested moving the placement of the controlsThings that went well:User was satisfied with the easy controlsWas easily held and comfortable in their handsAble to complete the task without major issuesThe prototype worked well to complete specified tasks but it was a challenge trying to fit all the features onto a small device. Another challenge was how to test a trigger that would rely on users pressure. Without outright telling the user how the device is reacting to their actions, it can be difficult to simulate. I would improve the layout of the controls by minimizing their size and moving the size selection to the handle. I would also use text instead of symbols to show the different screw head types because it seemed to confuse users during testing RELATED QUESTION What are POP materials when it comes to advertising?

Correct Use of Live Cable Identifier
Correct Use of Live Cable Identifier
The cable identifier has the main function of identifying a cable from a bundle of cables. The utility model is composed of a receiver and a connector of a signal generator and a sensor. It is commonly used in cable erection, migration, maintenance and fault handling. It is divided into live cable identifier and non live cable identifier. Let's talk about their own search methods. 1. Search method of live cable recognizer: when the line is live, we can't affect the normal operation. When identifying the cable with points, we use the induction method to measure. The high-frequency signal is transmitted through the caliper. After receiving the signal characteristics, the receiver filters through software and hardware. During phase identification, when the receiving caliper clamps the cable according to the current direction, the identified cable ammeter deviates to the right, Accompanied by audible and visual indication. The current direction of other cables is opposite to that of the identified cable, and the ammeter pointer deviates to the left. No audible and visual indication. This reflects the uniqueness of the identified target cable. It is easy to distinguish the identified cable from multiple cables. Since the signal current strength on the identified cable is the same throughout the line, the electromagnetic signal strength received by the receiving caliper along the cable is the same. In principle, the identified cable is not limited by the length of the identified cable. 2. Search method of dead cable identifier: the search method of dead cable identifier is basically connected with live identification. The generator feeds periodic unipolar voltage pulses into the cable to be identified. The cable needs to be grounded at the far end to ensure that enough current flows through the cable. The direction of pulse current fed into the cable can be used as an obvious identification standard, The outgoing current only passes through this cable. All other adjacent cables flow through the return current, but their polarity is opposite. The direction and size of the current flowing through the cable are detected through the receiver. It is equipped with an amplifier and connected in series in the circuit. The sensor clamps the measured cable. The magnetic field generated by the current flowing through the cable induces a voltage in the coil of the sensor, The voltage polarity is determined by the current direction and the direction of the sensor coil, so as to identify the cable. Since the cable shielding layer is usually connected to the ground, if other cables in the cable bundle are also connected to the public ground, the black output jack on the generator can be connected to the public ground. The return current is distributed in several cable shielding layers and divided into many tributaries, which means that the difference current of the identified cable is large and the useful signal is clear, The difference means that the output current and its divided return current are in the same channel.

The Differences Between Cable Recognizer and Other Power Fault Detection Equipment Are Analyzed
The Differences Between Cable Recognizer and Other Power Fault Detection Equipment Are Analyzed
Cable recognizer and cable fault tester have been introduced in previous articles. I believe you have a simple understanding of the functions and characteristics of these two devices. Some netizens have consulted Xiaobian before. What is the difference between the two devices? In order to meet everyone's thirst for knowledge, Xiaobian will give you a brief introduction today. The difference between cable identification instrument and cable fault tester: first of all, it should be distinguished. Cable identification instrument is the function of identifying cable, and cable fault tester is the function of finding path. It is basically the same in principle, and there are great differences in function and use method. For example, the measurement of cable fault tester must be in power failure state, while cable identification instrument can be live measurement; The cable identification instrument can accurately identify a cable, while the cable fault tester can only be an accurate path direction. Today, let's talk about the technical principle of the cable identification instrument and the use method of the cable identification instrument. 1、 Technical principle of cable identification instrument: firstly, the identified cable needs to be grounded at the far end. The generator feeds periodic unipolar voltage pulses into the cable to be identified, and the outgoing current only passes through this cable. All other adjacent cables flow return current, but their polarity is opposite. In addition to the difference in current direction, the current amplitude is also an identification feature, The outgoing current only passes through one cable, while the return current can pass through several cables, which means that the current flowing out is greater than the return current flowing through other cables. The receiver detects the direction and size of the current flowing through the cable, and the generated magnetic field induces a voltage in the sensor coil. The voltage polarity is determined by the current direction and the direction of the sensor coil, The voltage induced in the sensor coil displays the measurement result in the meter. 2、 Differences between cable identification instrument and cable fault tester 1. Set the test circuit. In order to ensure the normal use of the instrument, pay attention to setting the test circuit. Connect the red output jack to the core of the cable to be identified, connect the black output jack to the ground, and connect the cable core to the ground at the far end. 2. When the instrument calibrates the receiver, use the sensor to clamp the cable (close to the generator) at the beginning, the arrow points to the current direction, that is, to the far end of the cable, and then use the same receiving sensitivity for detection at the place to be detected. Use the sensor to clamp each cable once, and the arrow direction points to the far end of the cable. When the cable to be identified is clamped, The reading on the receiver meter is 4-6 grids and deflects to the right.
