Structured cabling network diagram. Structured cabling is the design and installation of a cabling system that will support multiple hardware uses and be suitable for today's needs and those of the future. With a correctly installed system, current and future requirements can be met, and hardware that is added in the future will be supported. [1]
In structured cabling, crosstalk refers to electromagnetic interference from one unshielded twisted pair to another twisted pair, normally running in parallel. Signals traveling through adjacent pairs of wire create magnetic fields that interact with each other, inducing interference in the neighboring pair.
When using more complicated setups through multiple patch panels in structured cabling, the connection can use multiple patch and building cable segments. It is a good idea to have all necessary crossovers on one side, i.e. either on the central hub/switch or on each secondary hub/switch.
FTTE / FTTZ (fiber-to-the-telecom-enclosure or fiber-to-the-zone): is a form of structured cabling typically used in enterprise local area networks, where fiber is used to link the main computer equipment room to an enclosure close to the desk or workstation. FTTE and FTTZ are not considered part of the FTTX group of technologies, despite the ...
The 8P8C jack used by structured cabling physically accepts the 6-position connector that fits RJ11, RJ14 and RJ25. Only lines 1 and 2 have electrical compatibility, with T568A wiring, and only line 1 with T568B wiring, because Ethernet-compatible pin assignments split the third pair of RJ25 across two separate cable pairs, rendering that pair ...
International standard ISO/IEC 11801 Information technology — Generic cabling for customer premises specifies general-purpose telecommunication cabling systems (structured cabling) that are suitable for a wide range of applications (analog and ISDN telephony, various data communication standards, building control systems, factory automation).
Permanent wiring used in structured cabling is solid. The category and type of cable can be identified by the printing on the jacket. [6] The Category 5 specification requires conductors to be pure copper. There has been a rise in counterfeit cables, especially of the copper-clad aluminum (CCA) variety. [7]
The cable management needs at either end are different (see also: Structured cabling). Buildings and office furniture are often designed with cable management in mind; for instance, desks sometimes have holes to pass cables, and dropped ceilings , raised floors and in-floor cellular raceway systems provide easy access.
