For a cabling installation to conform to this document the following applies.
a) The configuration and structure shall conform to the requirements outlined in Clause 5.
b) Channels shall meet the requirements specified in Clause 6 when subjected to environment conditions, local to the channels (see NOTE below),as defined by the applicable environmental Class(es) of Clause 6.
This shall be achieved by one of the following:
1) a channel design and implementation ensuring that the prescribed channel performance of Clause 6 is met;
2) attachment of appropriate components to a permanent link or CP link design meeting the prescribed performance class of Clause 7. Channel performance shall be ensured where a channel is created by adding more than one cord to either end of a link meeting the requirements of Clause 7;
3) for E1 environments, using the reference implementations of Clause 8 and compatible cabling components conforming to the requirements of Clauses 9, 10, and 11, that is based upon a statistical approach of performance modelling.
c) The interfaces to the cabling at the EO shall conform to the requirements of Clause 10 with respect to mating interfaces and performance when subjected to environment conditions, local to the connecting hardware (see NOTE below),as defined by the applicable environmental Class(es) of Clause 6.
d) Connecting hardware at other places in the cabling structure shall meet the performance requirements specified in Clause 10 when subjected to environment conditions, local to the connecting hardware (see NOTE below), as defined by the applicable environmental Class(es) of Clause 6.
The channel is the transmission path between data centre equipment such as switches and servers (EQP in Figure 5). A typical channel in a data centre would consist of the zone distribution cabling subsystem together with an equipment cord at each end. F or longer reach services，the channel would be formed by the connection of two or more subsystems (including patch cords and equipment cords), see Annex A. The performance of the channel excludes the connections at the application-specific equipment.
The permanent link is the transmission path of the fixed cabling subsystem, including the connecting hardware at the ends of the installed cable. In a data centre zone distribution cabling subsystem, the permanent link consists of the EO, an optional LDP cable, an optional LDP, the zone distribution cable and the termination of the zone distribution cable at the zone distributor.AS 11801.5 pdf free download.
