IEC 61156-13:2023 describes cables intended to be used for transmission of 10 Mbit/s over a single twisted pair and distances of up to 1 km. The transmission characteristics of these cables are specified up to a frequency of 20 MHz and at a temperature of 20 °C. Depending on the MICE environment and the installation conditions, either unscreened or screened cables can be used. Furthermore, to consider different maximum transmission lengths, two sets of requirements are specified. The cable type A-1000 is a design supporting up to 1 km channel length while the cable type A-400 is supporting up to 400 m channel length. A blank detail specification can be found in Annex A.
The cables covered by this document are intended to operate with voltages and currents normally encountered in communication systems. While these cables are not intended to be used in conjunction with low impedance sources, for example the electric power supplies of public utility mains, they are intended to be used to support the delivery of DC low voltage remote powering applications.

This third edition cancels and replaces the second edition published in 2003. This edition constitutes a technical revision and includes the following significant technical changes with respect to the previous edition:
a) new requirements for new cables Cat3, and Cat5 applications;
b) a better numbering in order to take into account the generic specification.
