How to Choose the Right Bnc Coax Cable Tester
This type of cable supplies power to the device in question and transmits the video signal to the output. The prefabricated Siamese cable is available in various lengths to keep most camera cables at a distance. The optical cable tester includes a plug for visible light sources that is compatible with the optical cable installation.A cable tester is a microcontroller that displays and automates the test process and displays the test results for multi-wire cables. It connects to the end of the cable separately with a display of the current source portion to allow the injection of test current from one end of a cable to detect the results from a remote end.To check a USB cable, you can perform simple USB tests by connecting the cable end to the appropriate port on the cable tester. You can also check your cloud services, data communications and data transmission by testing connection stability with network cable testers.There are a number of methods to test coaxial cables to obtain a reliable signal frequency. Following are the steps to test a coaxial cable with the help of a multimeter probe. This is a reliable method to test the coaxial cable without signal loss.A network cable tester is a revolutionary device designed to test the reliability and capability of cable connections. It is a necessity for network technicians, network testers, cable testers and other related work in this field. Cable network testers are not only reliable, but also able to fix problems and help you identify cable problems and connection problems.The coaxial cable RG-179 uses a 7.5 Ohm BNC connector and can be used in high temperatures. RG-6 coaxial cable is the "coaxial cable for the Internet" - it is used to transmit the signal over the Internet connection (the Internet signal runs at a higher frequency than traditional analog video). It can be operated up to a distance of RG-59 without loss of the video signal, but it is a thick and rigid cable that is not comfortable to work with.The RG-174 coaxial cable uses the 50 ohm BNC connector and is thin enough for wide applications such as GPS navigation antennas for cars and many vehicles. RG58 coaxial cables use the 50 ohm BNC connectors and are versatile due to their performance. The RG-59 coaxial cable is used to transmit video signals from a CCTV camera to a monitor in another room.Although 75 Ohm coax is likely the impedance found in most of today's applications, it is important to note that all components of a coaxial cabling system must have the same impedance to avoid internal reflections at connecting points that can cause signal loss and poor video quality. High-capacity cables can distort the transmission of digital signals by reducing the distinction between graduated peaks and sinks. 75 ohm coaxial cables are therefore of great benefit for digital transmission, and their lower capacity than 50 ohm cables ensures that all digital transmission passes through the wire with minimal losses or distortions.Digital Signal 3 signals (DS3 signals), which are used to transmit data traffic to the control panels, are called T3 lines and use coaxial cables comprising 7.5 ohms (type 735) and type 734. Type 735 cables are used for distances of up to 6.9 metres, while type 734 cables can be used for distances of up to 13.7 metres.There are various types of adapters for BNC connectors, including T connectors, cylinder connectors and terminators. They can be plugged into any type of connector or SDI signal transport connector.Choosing the right cable is a major problem that plagues most companies and teams. Choosing the right BNC connector for the cable for your project comes at a price. To avoid problems with your network, use BNC connectors instead of compressing or bolting cables.This guide to cabling security cameras provides a practical explanation of the cable types of surveillance cameras and termination cables for easy installation. Siamese cables for surveillance cameras are a two-wire solution with a cable assembly that enables easy video and power transmission to the BNC camera. Curveball Cat5E and Cat6 cables are used to send the video signal to the camera using a video balun adapter.When using a video balun network, the cable does not tip over and requires the lead wire to be exposed by removing the outer layer of the wire at each end.Connect one end of the coaxial cable tester to the socket and bring the other end to a point where several coaxial signal cables meet. The video signal and power supply are transmitted via a single network cable, similar to how Siamese cables work. Another method for network cables is to crimp the RJ45 connector and plug it into the socket of a video power baloon.When you touch the multimeter probe on the end of the right coaxial cable, the meter reads 0 but you will see different readings on the other cables.If your coaxial cable is on the wall, connect an end of the coaxial cable tester to the wall plate and point the other end to the tester to facilitate assembly of the entire cable. To find the right cable, touch the cable one way or the other and a beep will be generated. If it is the antenna on your roof, you can use a multimeter with an aluminum coil to track the right end of a particular coaxial cable.Once you traced and identified the coaxial signal of the cable that you want to test with a multimeter, the next step is to figure out how to perform the task. Touch the center of the conductor end of your coaxial cable with the multimeter probe.Confirm that the shielding patency at both ends of your coaxial cable is in good condition. A second test should be performed on the coaxial cable to determine the status of the screen continuity.

The LinkRunner LTRA offers a variety of cable testing techniques, including TDR, wiremapping, office identification and toning. The LTRA is designed to help troubleshoot wiring problems such as excessive cable routing, cable breaks, wall panels, patch panels, etc. It uses a combination of TDR and resistance measurements to map the wire, measure cable length and detect anomalies such as short, open or split pairs.The LRAT can measure an accurate cable length of 100 m or less with an accuracy of plus or minus 2 m. It can also be used to test terminated cables connected to an internal cable mapping port (WMAP) or an external cable identification accessory, as well as undermined and open cables. For pre-assembled and non-assembled cables, the fault detection is accurate to within 0.8 m of the error distance.This tester is a wiremapper that checks connections for CAT 5E / 6 certification, but can also test performance at higher frequencies. The threshold for the low voltage resistance is set insulated for 5 mO to a contact resistance of 0.1 O. This is measured with an embedded resistance at 100 O (1 mO x 1) to achieve an accuracy of less than -0.1 o (5 mO).In fact, certification testers can test wire diagrams, length attenuation, and crosstalk from one connection to another, helping you troubleshoot and save the results in a printed report for the customer. Cable certification testers are automated, so it's so easy to get a pass or fail at the touch of a button. Installers use certification testers to test cables that are being laid.There are a large number of cable testers on the market today, which means that there may be the right device for your purposes.

LC Duplex Fiber Connector for High-density Cabling
LC Duplex Fiber Connector for High-density Cabling
Due to its small size, LC connector is the mainstream fiber optic connectors and is widely used in optical communication networks, data networks, and cable television networks. In daily application environment, LC duplex connector used more often because of its cabling space saving. LC duplex fiber optic connector is two simplex LC connectors encased in a common housing. Compared with LC simplex connector, the installation steps are reduced, saving time and money.HYCs LC duplex connector is superior to traditional LC duplex connector, providing an innovative solution for quick unlocking. Compared to the traditional two single connectors, this duplex connector only needs one press to achieve double releasing. As shown in Figure 2,3, the design of this two-core connector has two advantages, one is the longer clip and another is a lower clip. The extended longer latch on top of the connector body makes it easier to disengage from the adapter, even in high-density packaging. If you have the experience of releasing LC duplex connectors in patch panels in high-density cabling, you may know why this is important. Because in the cabling case, thumbs and forefingers are not ideally suited to operate the release lever and pulling the connector. The handle portion of a conventional duplex connector will be slightly higher than the adapter, which will take up more space during the cabling installation. The lower clip design of this LC duplex connector can save more space. In the high-density environment of the data center, the space saved by multiple connectors is combined to have a great advantage.Another important advantage is the ability to reverse polarity. In the optical signal transmission, the optical signal is divided into a receiving end and a transmitting end. The optical fiber link transmitting signal (Tx) at one end of the optical cable must be matched with the corresponding receiver (Rx) at the other end, and the matching is called polarity.Conventional LC fiber jumpers have significant limitations in achieving polarity switching. It is necessary to pay special attention to the direction of polarity transformation to avoid the failure of termination and face the possibility of replacing the jumpers and re-cabling. The ability to switch the polarity of this LC duplex connector makes this operation easier, saving a lot of time and wiring costs by easily switching polarity without any tools.With the rapid application of 5G, how to provide a high-density, low-cost, easy-to-manage, and highly reliable network cabling system for data centers has become an increasingly important requirement. The LC duplex fiber optic connector is a high-reliability, low-cost, high-density cabling solution. Originally published at wordpress. com on April 27, 2019.

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.

Cable Identifier Manufacturers Popularize Science on Information Security of Power System
Cable Identifier Manufacturers Popularize Science on Information Security of Power System
China's science and technology are developing continuously and its economy is growing steadily. In this environment, the development speed of China's power industry is not the same as before. However, in today's society, facing the increasing demand for power in people's production and life, the power industry can ensure people's power consumption only by doing a good job in safe production. Now let the cable recognizer manufacturer popularize some knowledge about power system information security. In recent years, with the rapid development of power grid, especially power grid dispatching automation system, power dispatching control business has become the lifeblood of power system. According to the security protection regulations of power grid, power plant computer monitoring system and dispatching data network, the power control system must be effectively and safely isolated from the office automation system. The above-mentioned isolation means that the dispatching data network used by the power control system must be physically isolated from the public information network and the Internet, and a national power system information security protection system, security responsibility system and security joint defense system must be gradually established. The goal of power grid information security is to prevent the power grid, power plant computer monitoring system and dispatching data network from being attacked, prevent power system accidents caused by attacks, ensure the safe, stable and economic operation of power system, and protect the safety of important national infrastructure. Therefore, building the security protection system of dispatching automation system has become an important task of power grid dispatching automation in the future. Power grid information security has become an important link in the production, operation and management of power enterprises. 1、 Security protection scheme of main station of network dispatching automation system security protection strategy of main station of network dispatching automation system. Security zoning, network dedicated, horizontal isolation and vertical authentication are the basic strategies for security protection of power secondary system. Its core idea is two isolation, namely, effective and safe isolation between control system and office automation system, and physical isolation between dispatching data network, public information network and Internet. 2、 The basic principle of security protection of power real-time data network system. In theory, although the power real-time data network system with absolute security and confidentiality can not be established, if some reasonable principles are followed at the beginning of construction, the corresponding security and confidentiality will be greatly improved. When designing the security mechanism of power data network, we should follow the following principles from the perspective of Engineering Technology: among them, the integrity principle of network information security system comprehensively considers the factors such as security protection, monitoring and emergency recovery. Because the security and confidentiality of network information can not be guaranteed, it is required that when the network is attacked and damaged, the service of the network information center must be restored as soon as possible to reduce losses. Therefore, the security protection mechanism, security monitoring mechanism and security recovery mechanism of information security system should be included. Principle 2: Barrel Principle of security and confidentiality; It is necessary to consider the balance and comprehensive security protection of network data and information. The cable identifier manufacturer believes that it is a necessary prerequisite for designing the information security system to fully, comprehensively and completely analyze, evaluate and detect the security vulnerabilities and security threats (including simulated attacks) of the system.

Basic Principle of Live Cable Identification Instrument
Basic Principle of Live Cable Identification Instrument
As the running live cable is not allowed to damage any grounding wire and other connecting wires, nor is it allowed to directly add the output signal of the live cable identifier transmitter to the cable phase line with high voltage. Two difficult problems need to be solved for live cable identification. One is how to couple the cable identification signal to the cable; Second, the coupled signal is generally small, and the operating cable may have 50Hz power frequency electromagnetic interference composed of 50Hz unbalanced current, induced 50Hz interference current, cable distributed capacitance current, etc. the high-sensitivity receiving caliper has the problem of how to resist 50Hz power frequency interference. The charged cable identification instrument developed by US adopts single chip microcomputer coding and decoding technology and PSK technology widely used in the field of communication. The phase coded signal with an average value of 0 is transmitted on the transmitting caliper, and the single chip microcomputer in the receiving caliper performs phase identification after filtering the received signal by hardware and software. When the receiving caliper cards 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. In addition, 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.
