Data Cable Scalability Is Easy To Facilitate The Advantages Of Network Upgrades
- Sep 11, 2017 -

Data cable is divided into two types: one is the implementation of the Americas 100Ω cable, mainly for non-shielded twisted pair; the other is the implementation of the European 150Ω cable, mainly for shielded twisted pair.

With the rapid development of optical communication technology, China's cable communication network backbone network and inter-office trunk lines have been widely used fiber optic cable, fiber access access network has become an inevitable trend. But the cable laying costs are too high, the cost of the joint and the end of the optical - electricity conversion costs are expensive, so in the fiber before the popularity of a long period of time, access network subscriber line will still be the main metal cable. The metal cable mainly includes three kinds of plastic cable, coaxial cable and data cable. Among them, the data cable is the ideal transmission network of broadband access network, it has the advantages of low manufacturing cost, simple structure, good scalability and easy network upgrade. It is mainly used for building integrated wiring, integrated computer wiring The

Standard Overview: The latest version of the Commercial Building Communication Cable standard is ANSI / TIA / EIA-568-B. The TR-42 Technical Committee of the Telecommunications Industry Association TIA (Telecommunications Industries) has split the standard into B.1, B.2 and B.3 series. 568-B.2 includes information on the design, installation and field testing of general building cable systems; 568-B.2 and 568-B.3 include the manufacture of cables, patch cords and connectors, components Reliability test specification. 568-B.3 was released in April 2000 and is suitable for use in fiber optic components. 568-B.2 specifies the electrical and mechanical requirements for UTP and F / UTP, CAT3 and CAT5e cable and component requirements. 568-B.1 and 568-B.2 were issued in June 2001.

The ISO JTC1 SC25 / WG 3 Working Group has also issued the second edition of the ISO / IEC 11801 standard. The standard specifies the CAT6, CAT7 cable and its connections. 11801 is characterized by the provisions of the CAT7 working area interface and coupling attenuation. In the case of fiber optic cables, the standard provides for the three levels of 300m, 500m and 2000m serving both existing and future network applications. In the component requirements, 11801: 2002 reference to the IEC61156-5 horizontal layer and IEC61156-6 work area. With some minor exceptions, all of the requirements for the cable in 11801: 2002 can be found in both standards. For RJ-45 type socket, 11801: 2002 refer to IEC 60603-7-X (x = 1, 2, ... 7) series; for new RJ-45 type socket (TERA type connector), refer to IEC61076-3 -104.

In the first edition of ISO / IEC 15018, in the field of information and communication technology, household cables refer to the same cable provisions in 11801: 2002; in the field of broadcasting and communication technology, refer to IEC 1200MHz cable specification, IEC 61196-7 and IEC 61076 3-104.
