AS 11801.3:2019 Information technology — Generic cabling for customer premises
6.1 General
Clause 6 specifies the minimum channel performance of generic cabling at and between the connections to active equipment as shown in Figure 1 0 and comprises only passive sections of cable, connecting hardware, cords and jumpers.
The channel performance is specified as a combination of environmental performance and transmission performance.
The minimum requirements for the transmission performance of cabling channels are specified in 6.3. The required transmission performance Class shall be met for all environmental performance Classes specified for the channel.
Compatibility between the structures and materials at the interfaces between these components and assemblies shall ensure that the required mechanical, environmental and transmission performance is maintained for the intended life of the cabling.
Where applications listed in ISO/IEC 1 1 801 -1 :201 7, Annex E, are to be supported, the performance of the connections at the active equipment are the responsibility of the equipment supplier.
Application support depends on channel performance, which in turn depends on cable length,number of connections and performance of the components within the environments to which the channel is subjected.
Transmission and environmental performance shall be assured by the selection of cabling components suitable for the environmental Class(es) or by the use of pathway systems and installation practices that provide the required protection to the installed cabling.
6.3.3 Optical fibre cabling
The selection of optical fibre components shall take into account the applications to be supported, and the required channel lengths, and should take into account any predicted changes to the applications to be supported during the expected life of the cabling.
Cabling shall be designed using the cabled optical fibres referenced in 9.3 to provide channel performance as required to support the relevant applications of ISO/IEC 1 1 801 -1 :201 7,Annex E for the following parameters:
a) channel attenuation,
b) channel length.
Channel performance shall meet the requirements of ISO/IEC 1 1 801 -1 :201 7, 6.5.
