Introduction

This document contains requirements for cabling configurations which use cabling components meeting the requirements of EN 50173‑1 but in configurations that do not conform to the structure of generic cabling in the premises-specific documents EN 50173‑2 to EN 50173‑6.

These configurations are described as:

a) direct attach cabling;
b) end-to-end (E2E) links;
c) modular plug terminated links (MPTL).

The configurations of this document do not replace the generic cabling solutions of EN 50173‑2, EN 50173‑3, EN 50173‑4, EN 50173‑5 and EN 50173‑6.

The transmission performance of these configurations implemented using balanced cabling components is specified in terms of Class in order to indicate their ability to support the relevant applications of EN 50173‑1.

The transmission performance of these configurations implemented using optical fibre cabling components is not specified and refers the application support parameters of EN 50173‑1.

Remote powering is covered in EN 50174‑1 (Planning) and in EN 50174‑2 (installation).

The cabling configurations of this document are passive systems and cannot be tested for EMC compliance individually. Application-specific equipment, designed for one or more cabling media, is required to meet relevant EMC standards on those media. Care should be taken that the installation of any of those media in a cabling system does not degrade the characteristics of the cabling. The installation methods of EN 50174 series should be used to minimise the effect of electromagnetic disturbances.

Figure 1 and Table 1 show the schematic and contextual relationships between the standards produced by TC 215 for information technology cabling, namely:

1) this and other parts of the EN 50173 series;
2) installation (EN 50174 series);
3) bonding (EN 50310).

In addition, a number of Technical Reports have been developed to support or extend the application of these standards, including:

— CLC/TR 50173‑99‑1 , Cabling guidelines in support of 10 GBASE-T;
— CLC/TR 50173‑99‑2 , Information technology — Implementation of BCT applications using cabling in accordance withEN 50173-4;
— CLC/TR 50173‑99‑3 , Information technology — Generic cabling systems — Part 99-3: Home cabling infrastructures up to 50 m in length to support simultaneous and non simultaneous provision of applications.

In addition, a number of cabling design standards have been developed using components of EN 50173‑1 (e.g. EN 50098 series and EN 50700).
