This part of ISO/IEC 11801, which is a Technical Report,

a) describes the rules of implementation of balanced single pair cabling as specified by ISO/IEC 11801-6 [3] within a balanced 4-pair cabling system with a current carrying capacity of 0,75 A per conductor as specified in ISO/IEC 11801-1:2017 [2];

b) describes the use of ISO/IEC 11801-1:2017 [2] components and cabling to implement and configure in accordance with ISO/IEC 11801-3:2017/AMD1:2021 [4], ISO/IEC 11801-4 [5] and ISO/IEC 11801-6 [3];

c) describes links and components for generic single pair channels in accordance with ISO/IEC 11801-1:2017/AMD1:- [1]. Particular areas of interest are
1) remote powering in accordance with IEEE Std 802.3dd [6],
2) loop resistance and maximum current,
3) insertion loss,
4) return loss,
5) noise considerations,
6) frequency range requirements (low and high),
7) length calculation of the SCP link 4-pair-cable, and
8) number of channels;

d) describes the use of application-specific single pair channels in addition to ISO/IEC 11801- 1:2017/AMD1:- [1], 6.6.4;

e) describes guidance on single pair remote powering applications when using 4-pair cabling with current carrying capacity specified by ISO/IEC 11801-1:2017 [2];

f) describes guidelines for planning, administration and installation.

NOTE: This document compares requirements of existing 4-pair cabling classes and single-pair classes. The described approach can be adjusted to any number of pairs.
