Information technology - Generic cabling for customer premises - Part 9906: Balanced single-pair cabling channels up to 600 MHz for single-pair Ethernet (SPE)
ISO/IEC TR 11801-9906:2025 covers cabling channel specifications, for cabling channels constructed from balanced single-pair cabling components, primarily intended for use in industrial automation and process control applications.
The cabling channel specifications are intended to support ISO/IEC/IEEE 8802-3 single-pair Ethernet (SPE) link segment specifications in the following SPE physical layer specifications (PHYs):
a) 1000BASE T1 Type B (bp), with reach up to 40 m;
b) 1000BASE T1 Type A (bp), with reach up to 15 m;
c) 100BASE T1L (dg), with reach up to 500 m;
d) 100BASE T1 (bw), with reach up to 15 m;
e) 10BASE T1L (cg), with reach up to 1000 m;
f) 10BASE T1S (cg), with reach up to 15 m.
The channel component specifications are referenced according to corresponding IEC balanced single-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.
ISO/IEC TR 11801-9906:2025 cancels and replaces the first edition published in 2020. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) the addition of ISO/IEC/IEEE 8802-3, 100BASE T1L (dg), long reach;
b) complete rearrangement of the information contained in Clause 4, Clause 5, Annex A, Annex B, and Annex C.

Part 9906: Balanced single-pair cabling channels up
to 600 MHz for single-pair Ethernet (SPE)
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.
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 and ISO National bodies.
3) IEC and ISO documents have the form of recommendations for international use and are accepted by IEC and
ISO National bodies in that sense. While all reasonable efforts are made to ensure that the technical content of
IEC and ISO documents is accurate, IEC and 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 and ISO National bodies undertake to apply IEC and ISO
documents transparently to the maximum extent possible in their national and regional publications. Any
divergence between any IEC and ISO document and the corresponding national or regional publication shall be
clearly indicated in the latter.
5) IEC and ISO do not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC and ISO marks of conformity. IEC and ISO 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 document.
7) No liability shall attach to IEC and ISO or their directors, employees, servants or agents including individual
experts and members of its technical committees and IEC and ISO National 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, use of, or reliance upon, this ISO/IEC document or any
other IEC and ISO documents.
8) Attention is drawn to the Normative references cited in this document. Use of the referenced publications is
indispensable for the correct application of this document.
9) IEC and ISO draw attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC and ISO take no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, IEC and ISO had not received notice of
(a) patent(s), which may be required to implement this document. However, implementers are cautioned that this
may not represent the latest information, which may be obtained from the patent database available at
https://patents.iec.ch and www.iso.org/patents. IEC and ISO shall not be held responsible for identifying any or
all such patent rights.
