The CI810 FCI and the TB815 Interconnection Unit have a connection to the optical
ModuleBus expansion by the TB810/TB811 ModuleBus Optical Port connection on
its front. The fiber optic cable(s) connect to the Tx and Rx ports of the
TB810TB811. The optical ModuleBus can be connected to duplex or simplex fiber
optic cables. See

FCI
The TB815 Interconnection Unit also connects the same way to the TB810/TB811
ports.
The connector style, either simplex or duplex, all provide snap-in action when
mated to the TB810/TB811 ports. Simplex connectors are color coded to facilitate
identification of transmitter (Tx) or receiver (Rx) connections. Duplex connectors
are keyed so that proper orientation is ensured during insertion.
For simplex cables by convention, the gray connector is the transmitter end and the
blue connector is the receiver end.
