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 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 301 29 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 installation shall be defined in the installation specification and quality plan for that installation prepared in accordance with ISO/IEC 1 4763-2. For installations beyond the IID, IEC 61 91 8 and IEC 61 784-5 series shall be met (see Annex A). In the absence of the channel, the conformance of the link shall be used to verify conformance with this document. Specifications marked “ffs” are preliminary specifications, and are not required for conformance to this document. NOTE The applicable environment of ISO/IEC 1 1 801 -1 :201 7, 6.2.2, local to the cabling or cabling component(s), is that of the external environment or that modified environment created by use of mitigating installation techniques.
5 Structure of the generic cabling system 5.1 General Clause 5 identifies the functional elements of generic cabling for industrial premises, describes how they are connected together to form subsystems and identifies the interfaces at which application-specific components are connected. Applications listed in ISO/IEC 1 1 801 -1 :201 7, Annex E, are supported by connecting active equipment at the TOs and the distributors. In general, all functional elements, subsystems and interfaces from the campus distributor to the floor distributor as described in ISO/IEC 1 1 801 -1 are applicable. 5.2 Functional elements In addition to the functional elements of ISO/IEC 1 1 801 -1 , cabling in accordance with this document specifies the following functional elements: a) floor distributor (FD), b) floor cable, c) intermediate distributor (ID), d) intermediate cable, e) consolidation point (CP) – optional, f) consolidation cable (CP cable), g) telecommunications outlet (TO). As shown in Figure 3, an ID is able to serve TOs on separate pieces of apparatus or multiple TOs on a single piece of apparatus. The type and nature of the apparatus cabling are beyond the scope of this document. Groups of the functional elements are connected together to form cabling subsystems.
