The following bit significant indicators define the FC interfaces that are supported by the transceiver. The defined identifier values are: - Fibre Channel link length: Bits 0: very long distance (V) Bits 1: short distance (S) Bits 2: intermediate distance (I) Bits 3: long distance (L) - Fibre Channel transmitter technology Bits 4: Longwave laser (LC) Bits 5: Electrical inter-enclosure (EL) Bits 6: Electrical intra-enclosure (EL) Bits 7: Shortwave laser w/o OFC (SN) Bits 8: Shortwave laser w/ OFC (SL) Bits 9: Longwave laser (LL) Bits 10: Copper Active Bits 11: Copper Passive - Fibre Channel transmission media Bits 12: Twin Axial Pair (TW) Bits 13: Shielded Twisted Pair (TP) Bits 14: Miniature Coax (MI) Bits 15: Video Coax (TV) Bits 16: Multi-mode, 62.5m (M6) Bits 17: Multi-mode, 50 m (M5) Bits 18: Single Mode (SM) - Fibre Channel speed Bits 19: 800 MB/Sec Bits 20: 400 MB/Sec Bits 21: 200 MB/Sec Bits 22: 100 MB/Sec Bits 23: 1200 MB/Sec Bits 24: 1600 MB/Sec.
