This International Standard describes a physical interface for Fibre Channel that is based on and adds to ISO/IEC 14165-115. It specifies a Medium Dependent Interface for 1000BASETX2/4 PHY layers as defined in ISO/IEC 7498-1 together with the consequences for the physical layer and the MAC (TBI) Interface. Scrambling, coding and modulation necessary to provide a bit error rate of 10-12 or less are specified. This standard also specifies the requirements for the medium (transmission channel). These requirements are within the minimum performance of a dedicated balanced Class F channel (in general made of up to 100 m Class F balanced (twisted pair) cabling, as specified in ISO/IEC 11801:2002). This International Standard supports full duplex transmission with a signalling rate of 1 062,5 Mbit/s.

This International Standard provides a low-complexity Media Independent Interface and the functional description of an Ethernet physical layer for 100 MB/s transmission that can easily be implemented by many vendors. This standard takes advantage of the improved transmission characteristics provided by balanced cabling channels of Class F, as specified in ISO/IEC 11801:2002.
