Coaxial cables - Part 3-1: Sectional specifications for cables used in Telecom applications - Miniaturized cables used in digital communication systems
This European Standard relates to EN 50117 1 and should be read in conjunction with this generic specification. This standard applies to single and/or multiple miniaturised coaxial cables used in digital communication systems on the Telecom applications.
The cables covered by this standard are used for the internal wiring of and interconnection between switching-, transmission-, multiplexing- and cross-connect equipment and for the connections to the digital distribution frame.
These coaxial cables are designed for the transmission of E1 (2 Mbit/s), E2 (8 Mbit/s), E3 (34 Mbit/s), E4 (140 Mbit/s), STM (155 Mbit/s), DS1 (1,5 Mbit/s), DS2 (6 Mbit/s) and DS3 (34 Mbit/s) signals.
Cables are connected to the equipment via a coaxial connector or other suitable ways.
The purpose of this standard is to specify the applicable test methods and requirements for the electrical, mechanical, environmental and fire performance of the cables.
The cables covered by this standard are intended to be used with voltages up to 50 V a.c. and/or 120 V d.c.
