The FIP (see the following figure) provides one high-speed (100 Mbps) FDDI port. Two types of FIPs are available:
CX-FIP-MM — multimode to multimode with optical bypass
CX-FIP-SS — single-mode to single-mode with optical bypass
The last two letters of the FIP type name indicate the functions of the PHY-A and PHY-B connectors, respectively. Thus, for the CX-FIP-MM (multi-mode to multi-mode) FIP, PHY-A is multi-mode and PHY-B is multi-mode. For the CX-FIP-SS (single-mode to single-mode) FIP, PHY-A is single-mode and PHY-B is single-mode.
