This part of IEC 61156 describes cables intended to be used for transmission of 10 Mb/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 part of IEC 62783 specifies definitions, requirements and test methods of twinax cables used in digital communication systems, e.g. computer rooms, data centers, Server, etc. These cables are intended to be used indoors.

This generic specification details the requirements and transmission characteristics for single twinax element as well as multiple twinax elements within the same sheath, i.e. “twinax cable”.

This document is applicable to twinax cables and also twinax cable assemblies.

This generic specification is supplemented with family specifications that shall give additional requirements based on the specific application, e.g. the minimum and maximum specified frequency of the cables.
