What is BS IEC 61156-9 - Cables for channels with transmission characteristics up to 2 GHz about ?
BS IEC 61156 is an international standard that discusses multicore and symmetrical pair/quad cables for digital communications. BS IEC 61156-9 provides the sectional specification for Cables for channels with transmission characteristics up to 2 GHz to standardize their performance.
BS IEC 61156-9 is the ninth part of a multi-part series that describes cables primarily intended for the fixed part of channels as defined in ISO/IEC 11801 and in ISO/IEC TR 11801-9901 which is planned to be included in the next edition of ISO/IEC 11801-1.
BS IEC 61156-9 covers overall screened cables with screened (X/FTP) or unscreened (X/UTP) pairs, where X stands for F, S, or SF, as well as pair-screened cables without an overall screen (U/FTP).
The transmission characteristics of these cables are specified up to a frequency of 2 000 MHz and at a temperature of 20 °C.
Two categories of cables are recognized under BS IEC 61156-9:
- Category 8.1 for use in Class I according to ISO/IEC TR 11801-9901
- Category 8.2 for use in Class II according to ISO/IEC TR 11801-9901
The cables covered by BS IEC 61156-9 are intended to operate with voltages and currents normally encountered in communication systems.
Note: These cables are not intended to be used in conjunction with low impedance sources, e.g., the electric power supplies of public utility mains, they are intended to be used to support the delivery of low voltage remote powering applications such as IEEE 802.3af (Power over Ethernet) or further developments e.g., according to IEEE 802.3at or IEEE 802.3bt.
