Explanation of application strategies of optical fiber access technology

, talking about the strategies for developing FTTH application technology in China. 1. features of China's FTTH target marketThe main target market of FTTH in China is undoubtedly the residents of residential areas in large and small cities. Urban residential areas are generally garden-style residential areas, which are characterized by high household density, A single Garden Residential Area generally has-households, and some even tens of thousands of households. residential areas, including co

Key Points of IDC Cabling System Construction

Cabling SystemThere are two methods: "field" and "well. The "field" is more suitable for the layout of the ring data center, and the "well" is more suitable for the layout of the vertical and horizontal data center. Its location can be arranged under the floor and under the ceiling, each with its own characteristics. The following describes the issues that need to be paid attention to during the wiring process: Key Points of Integrated Wiring Construction 1. Reasonable architecture design to ens

Fluke: cable search, not available to anyone

Currently, cabling system installers and network technicians are still using older Cable Fault Locating tools based on analog technology that was just 40 years ago. Even tools that use these simulation technologies often identify cables incorrectly or cannot discover signals in common work environments, they are the only choice. This is the case until today. R D engineers of fluke networks have applied decades of specialized cable testing technologie

Misunderstanding of FTTH Technology Application

, there will be uncertainty in future promotion, however, the point-to-point passive network structure is not suitable for high-density residential area applications in China. Moreover, EPON and GPON related devices require at least five years of standardization and maturity, in the next five years, it will be difficult to compete with the current cost and popularity of Ethernet P2P devices. At present, optoelectronic devices are far from meeting the requirements of low-cost PON systems. It can

Optical fiber and Cable

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 the optical fiber inside the core. A thin pl

What are network cabling options-optical fiber or copper cable?

A few years ago, people thought that the unshielded twisted pair copper cable had reached its limit in the fifth category of MHz. Many users and manufacturers turned their attention to the optical fiber and thought that the optical fiber is an inevitable transitional path for IT facilities. The optical fiber solves the disadvantages of unshielded twisted pair wires in various aspects: it has higher bandwidth, longer distance, higher security, completely eliminates RFI and EMI, and allows closer

Analysis of Optical Fiber Application Technology Based on Cabling Technology

Analysis of Optical Fiber Application Technology Based on Cabling Technology 1 key points of data center optical fiber design (1) minimum allowable bending radius: In which case the installation of optical fiber is much easier than that of coaxial and UTP copper cables. The most important factor in cable installation is to keep the minimum bending radius of the cable. When the optical cable is smaller than the minimum allowable bending radius, the lo

Introduction to halogen of Integrated cabling cable outer skin

Standard Organizations and manufacturers in North America and Europe have long been arguing over the selection and standards of the outer skin of Integrated cabling network data cables, just as they are still using FTP shielding products for UTP. Currently, North America, South America, Asia Pacific, and China all adopt the North America-based cable fire prevention standard UL and NEC (National Electrical Code ), in some parts of Europe, low halogen o

Access Network market enters a new era

China's access network market is still developing very rapidly, not only optical fiber or copper cable, but also very well. Here we mainly introduce enterprises that pay more attention to industrial applications, this section describes the rapid growth of light and the application of copper cables. The cable manufacturing industry, which is applied in the access network market, has gained stronger enterprise vitality. At the exhibition, cable companie

Cable purchasing for network cabling

about 30% of the information points of the original 5 types of cabling products may fail the electrical performance test when supporting gigabit network applications, that is to say, not all five types of cables can run Gigabit Ethernet, which is mainly reflected in whether the electrical performance meets the requirements for full-duplex transmission of 4 pairs of cores required by Gigabit Ethernet, that is, starting from full-duplex transmission in

Cable safety level in cabling specifications

The cabling industry is strictly regulated in terms of transmission performance and security. Wiring security is crucial. Various standard entities and industry bodies around the world have prepared comprehensive documents for this purpose. One of the most recognized authoritative organizations for wiring security is the U. S. Insurance vendor lab UL), a non-profit organization dedicated to establishing and maintaining security standards for multiple industries. UL provides a large number of qua

Indoor high-speed optical cable (Fluke): how to test the network based on laser technology

Twisted Pair wires

I. OverviewTwisted Pair wires (TP: Twisted Pairwire) are the most commonly used transmission medium in integrated cabling. Twisted Pair wires are composed of two copper wires with an insulating protective layer. The two insulated copper wires are twisted together at a certain density to reduce signal interference, the electric waves emitted by each wire during transmission are offset by the electric waves sent from the other wire. Twisted Pair wires generally consist of 22 ~ The No. 26 insulated
