Information technology -- Generic cabling for customer premises

ISO/IEC TR 11801-9906:2020(E) covers channel specifications, for channels constructed from balanced 1 pair cabling components, primarily intended for use in industrial automation and process control applications. The channel specifications are consistent with corresponding IEEE 802.3 single-pair Ethernet (SPE) applications and are referenced from link segment specifications in the following IEEE SPE physical layer specifications: • ISO/IEC/IEEE 8802-3:2017/AMD4, 1 000 Mb/s: 1000BASE T1 Type A, = 15 m, 1000BASE T1 Type B, = 40 m; • ISO/IEC/IEEE 8802-3:2017/AMD1, 100 Mb/s: 100BASE T1, = 15 m; • IEEE 802.3cg, 10 Mb/s: 10BASE T1S, = 15 m; 10BASE T1L, = 1 000 m. The channel component specifications are referenced according to corresponding IEC balanced 1 pair cable and connector specifications. Channel specifications include IL, RL, TCL, coupling attenuation, and alien crosstalk parameters specifications. Channel EMC related specifications include electromagnetic isolation levels E1, E2 and E3, which are defined according to the MICE standard environmental characterization system specified in ISO/IEC 11801-1

FOREWORD

1) ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission)

form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC

participate in the development of International Standards through technical committees established by the

respective organization to deal with particular fields of technical activity. ISO and IEC technical committees

collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in

liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have

established a joint technical committee, ISO/IEC JTC 1.

2) The formal decisions or agreements of IEC and ISO on technical matters express, as nearly as possible, an

international consensus of opinion on the relevant subjects since each technical committee has representation

from all interested IEC National Committees and ISO member bodies.

3) IEC, ISO and ISO/IEC publications have the form of recommendations for international use and are accepted by

IEC National Committees and ISO member bodies in that sense. While all reasonable efforts are made to ensure

that the technical content of IEC, ISO and ISO/IEC publications is accurate, IEC or ISO cannot be held

responsible for the way in which they are used or for any misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees and ISO member bodies undertake to

apply IEC, ISO and ISO/IEC publications transparently to the maximum extent possible in their national and

regional publications. Any divergence between any ISO, IEC or ISO/IEC publication and the corresponding

national or regional publication should be clearly indicated in the latter.

5) ISO and IEC do not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. ISO or IEC are not responsible for

any services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or ISO or its directors, employees, servants or agents including individual experts

and members of their technical committees and IEC National Committees or ISO member bodies for any personal

injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including

legal fees) and expenses arising out of the publication of, use of, or reliance upon, this ISO/IEC publication or any

other IEC, ISO or ISO/IEC publications.

8) Attention is drawn to the normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this ISO/IEC publication may be the subject of

patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

The main task of IEC and ISO technical committees is to prepare International Standards.

However, a technical committee may propose the publication of a Technical Report when it has

collected data of a different kind from that which is normally published as an International

Standard, for example "state of the art".

ISO/IEC TR 11801-9906, which is a Technical Report, was prepared by subcommittee 25:

Interconnection of information technology equipment, of ISO/IEC joint technical committee 1:

Information technology.

INTRODUCTION

This document is a compendium of balanced 1-pair cabling channels specifications related to

specific applications.

The balanced 1-pair cabling channels support single-pair Ethernet (SPE) applications,

according to ISO/IEC/IEEE 8802-3:2017/AMD4, 1000BASE-T1;
ISO/IEC/IEEE 8802-3:2017/AMD1, 100BASE-T1; and IEEE 802.3cg, 10BASE-T1.

While the original use case for SPE was automotive applications, this document describes

balanced 1-pair cabling channels intended for use in non-automotive, SPE applications – for

example:

• industrial automation applications, Industrial Internet of Things (IIoT), Industry 4.0;

• enterprise building applications, Internet of Things (IoT), smart lighting, energy

management, and access control;
• other IoT applications, smart building and home automation applications.

SPE cabling channels support bidirectional signal transmission, using one balanced pair,

for 1 000 Mbit/s (ISO/IEC/IEEE 8802-3:2017/AMD4) up to 40 m, 100 Mbit/s

(ISO/IEC/IEEE 8802-3:2017/AMD1) up to 15 m, or 10 Mbit/s (IEEE 802.3cg) up to 1 000 m,

where reach is influenced by cabling channel capacity limitations from signal loss and

electromagnetic interference.

SPE channels optionally support power delivery together with the signal delivery over a single

balanced pair. Remote powering over balanced 1-pair cabling is addressed in
ISO/IEC TS 29125:2017/AMD1 .

1 Scope

This document covers channel specifications, for channels constructed from balanced 1-pair

cabling components, primarily intended for use in industrial automation and process control

applications.

The channel specifications are consistent with corresponding IEEE 802.3 single-pair Ethernet

(SPE) applications and are referenced from link segment specifications in the following IEEE

SPE physical layer specifications:
• ISO/IEC/IEEE 8802-3:2017/AMD4, 1 000 Mb/s: 1000BASE-T1 Type A, ≤ 15 m,
1000BASE-T1 Type B, ≤ 40 m;
• ISO/IEC/IEEE 8802-3:2017/AMD1, 100 Mb/s: 100BASE-T1, ≤ 15 m;
• IEEE 802.3cg, 10 Mb/s: 10BASE-T1S, ≤ 15 m; 10BASE-T1L, ≤ 1 000 m.

The channel component specifications are referenced according to corresponding IEC

balanced 1-pair cable and connector specifications.

Channel specifications include IL, RL, TCL, coupling attenuation, and alien crosstalk

parameters specifications.

Channel EMC related specifications include electromagnetic isolation levels E , E and E ,

1 2 3

which are defined according to the MICE standard environmental characterization system

specified in ISO/IEC 11801-1.

Channel signal transmission specifications for balanced 1-pair cabling are referenced from

three physical layer specifications: ISO/IEC/IEEE 8802-3:2017/AMD1,
ISO/IEC/IEEE 8802-3:2017/AMD4 and IEEE802.3cg. These cover five link segment

specifications: 1000BASE-T1 Type A, 1000BASE-T1 Type B, 100BASE-T1, 10BASE-T1S, and

10BASE-T1L. IEEE SPE link segment specifications and physical layer standards are

summarized in Annex C.

The SPE link segment specifications are identified by their corresponding upper frequency

specification, i.e. 600 MHz, 66 MHz, and 20 MHz.

The SPE signal transmission functional space covered by the five link segment specifications
