1, test the speed of network cable The transmission speed of the network cable is the most effective way to discriminate the quality of the network cable. In order to be closer to the actual use of the environment, while reducing the external interference link, the author recommends the use of two-machine direct-linked way. At the same time in order to ensure th

Cutting-edge Cable TechnologyAdd the colored optical fiber and oil paste to the rubber sleeve tube made of high modulus plastic at the same time, the optical fiber can be moved in the casing. The cable core is made by adding a strong core along the center of different cable casings. The cable core and protective materi

With the development of the network, as a kind of medium for transmitting data in the integrated wiring system, optical fiber is more and more used by people because it has the advantages of high transmission rate and far distance. As we all know, optical fibers are non-conductive, can be free of shock current, optical fiber cable also has good protection performance, the metal components in the cable to th

Overview Verify multimode and Single-mode optical cables Measurement of optical power and loss to ensure cable network performance Self-motion measuring wavelength function prevents measurement errors Store 100 Test Results Use Linkware cable management software to manage test results and print professional test reports Product Features The Simplifiber network is inexpensive and easy to use, while su

In 1972, Cabo-fi took the lead in launching a metal mesh cable tray in the European market. After more than 30 years of development, Cabo-fi cable trays have been laid more than 150,000 kilometers around the world, it is widely used in various engineering projects. It is not only solid and secure, but also more flexible and simple than traditional bridges. As a result, it is increasingly used in data center

During project installation, due to the limited conditions, the Network cables are all made on site. Generally, you do not need to perform an instrument test. You only need to use the indicator lights to preliminarily determine whether the network cables are turned on or off. However, the indicator lights sometimes do not reflect the network cables, some soft faults existing in the production of Network cables cannot be found at the moment. After a while, they will be gradually exposed. The foll

With the extensive laying and use of optical fiber lines, the reliability and security of optical fiber communication systems have attracted more and more attention. Due to the vast territory of China, the terrain and landform are quite different, which may cause many dangerous factors to optical cable lines, including various natural factors and man-made damage to optical cable lines. From the past Analysi

Currently, the access network technology is widely used, and the access network technology is also very commonly used. So I have studied the problems related to the access network technology construction planning and practical application. I will share with you here, I hope it will be useful to you. With the rapid development of broadband multimedia services and optical fiber communication technology, optical fiber communication technology has been more and more widely used in access network tec

The horizontal twisted pair wires in the cabinet are located on the rear side of the Cabinet. In the past, the twisted pair wires were not organized or simply bundled before being immediately mounted to the distribution frame. At that time, from the back of the Cabinet, the horizontal twisted pair wires were hanging like waterfalls, or several nylon cable ties can be bundled on either side of the Cabinet. Everyone is concerned about the performance te

Network cable classification and purchasing A network cable in the broad sense includes coaxial cables, telephone lines, optical fiber cables, and twisted pair wires. According to the Ethernet standard set by IEEE, twisted pair wires are most suitable for common LAN with a star topology. The twisted pair uses rubber as the Housing material, and contains 4-to-8 copper core plastic wires of different colors

Introduction to computer network structured Integrated Wiring System StructuredCablingSystem (SCS) is a module system based on star topology developed by Bell laboratory experts for many years. It is also the preferred system for LAN construction. The system has the advantages of practicality, flexibility, economy, modularization and scalability. It can connect data communication equipment with other information management systems and connect these devices to external communication networks. SCS

1. Overview With the development of information society, network technology has become more and more complex, and as the cornerstone of the network, keel-network cable appears more important. In the current network, there are three kinds of cable media: Optical cable, coaxial cable and digital twisted

The local area network is the individual computer or the terminal, uses the communication line to connect each other, follows certain agreement, carries on the information exchange, realizes the resource sharing. Among them, communication lines, that is, transmission medium commonly used: twisted-pair, coaxial cable, optical fiber and so on. From the cost-performance and maintainability, most LANs use unshielded twisted pair (utp-unshielded Twisted Pa

I. Optical Fiber1. OverviewThe optical fiber is similar to the coaxial cable, but there is no mesh shielding layer. The center is the glass core of light transmission. In multimode optical fiber, the core diameter is 15mm ~ 50mm, roughly equivalent to the hair width of a person. The diameter of the Single-Mode Optical Fiber Core is 8mm ~ 10mm. The outside of the core is surrounded by a glass envelope with a lower refractive index than the core to keep
