Most are subsequently incorporated into standards or released as standards by organizations such as the EIA, ANSI, and IEC. The following abridged list of SFF Specifications includes those referenced by the Serial Attach SCSI, Fibre Channel, Ethernet 802.3 and InfiniBand standards. Molex is an active participant in the SFF Committee.
