IEC 61156-5:2002 Multicore and symmetrical pair/quad cables for digital communications - Part 5: Symmetrical pair/quad cables with transmission characteristics up to 600 MHz; Horizontal floor wiring; Sectional specification
This sectional specification relates to IEC 61156-1: Multicore and symmetrical pair/quad cables for digital communications - Part 1: Generic specification. The cables described herein are specifically intended for horizontal floor wiring in class D, E and F channels, as defined in ISO/IEC 11801:2000, Information technology - Generic cabling for customer premises (see Table 1).
It covers individually screened (STP), common screened (FTP) and unscreened (UTP) pairs or quads having a pair count of four pairs or less. The transmission characteristics of the cables are specified at 20 ℃. See Annex A for a discussion of cable performance at temperatures higher than 20 ℃.
The designation "Category 5e" is used herein to describe an enhanced Category 5 cable and is used in the same context as "Category 5" in ISO/IEC 11801. This enhanced cable is designated Category 5e to differentiate it from the Category 5 cables described in IEC 61156-2, 61156-3, and 61156-4. Although both Category 5 and 5e cables are characterized to 100 MHz and can be used in Class D channels, Category 5e has additional requirements, as compared to Category 5, which make it preferred for use in systems utilizing four pairs transmitting simultaneously in both directions.
These cables can be used for various communication systems that are under development and which use as many as four pairs simultaneously. In this sense, this sectional specification provides the cable characteristics required by system developers to evaluate new systems.
The cables covered by this sectional specification are intended to operate with voltages and currents normally encountered in communication systems. These cables are not intended to be used in conjunction with low impedance sources, for example, the electric power supplies of public utility mains.
Though the recommended temperature range during installation is 0 ℃ +50 ℃, the actual temperature range during installation should be indicated in the detail specification.
