IEC 61156-11:2019 describes cables intended to be used for transmission of 1 Gbps over a single twisted pair for office, home and industrial application. An example of existing application is 1000BASE-T1, see ISO/IEC TR 11801-9906. The transmission characteristics of these cables are specified up to a frequency of 600 MHz and at a temperature of 20 °C. The cable type recognised is intended to be used for shielded channels with a nominal length of 40 m. Possible designs are U/FTP, X/UTP and X/FTP...view more

IEC TR 61839-2:2019 specifies the PSR (product specific rules) for optical/copper telecom accessories products. It covers the use, installation and end of life stages and provides methodological precisions to PEP/PCR writing for “optical/copper telecom accessories” products used for communication, data, control and command. PSR and general rules all together form the product category rules.
This specification document is primarily intended for:
· environment and/or product managers;
· LCA (li...view more
