AS 11801.2 pdf download.Information technology — Generic cabling for customer premises
1 Scope
This part of ISO/IEC 1 1 801 specifies generic cabling for use within office premises, which can comprise single or multiple buildings on a campus. It covers balanced cabling and optical fibre cabling. This document is optimized for premises in which the maximum distance over which telecommunications services can be distributed is 2 000 m. The principles of this document can be applied to larger installations. Cabling specified by this document supports a wide range of services including voice, data, and video that can also incorporate the supply of power. This document specifies directly or via reference to ISO/IEC 1 1 801 -1 a) the structure and minimum configuration for generic cabling within office premises, b) the interfaces at the telecommunications outlet (TO), c) the performance requirements for cabling links and channels, d) the implementation requirements and options, e) the performance requirements for cabling components, f) the conformance requirements and verification procedures. Safety (e.g. electrical safety and protection and fire) and electromagnetic compatibility (EMC) requirements are outside the scope of this document, and are covered by other standards and by regulations. However, information given by this document can be of assistance.

4 Conformance
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 E 1 environments, using the reference implementations of Clause 8 and compatible cabling components conforming to the requirements of Clauses 9, 1 0, and 1 1 , that is based upon a statistical approach of performance modelling. c) The interfaces to the cabling at the TO shall conform to the requirements of Clause 1 0 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 1 0 when subjected to environment conditions, local to the connecting hardware (see NOTE below), as defined by the applicable environmental Class(es) of Clause 6. e) The requirements of ISO/IEC 1 4763-2 and ISO/IEC 3021 9 shall be met. This document does not specify which tests and sampling levels should be adopted. Test methods to assess conformance with the channel and link requirements of Clause 6 and Clause 7, respectively, are specified in ISO/IEC 1 1 801 -1 . The test parameters to be measured, the sampling levels and the treatment of measured results to be applied for particular installations shall be defined in the installation specification and quality plan for that installation, prepared in accordance with ISO/IEC 1 4763-2.
