Table 10A.AC lists the connectors used to make the fiber optic
connections to the I/O ring. Each module connected to the system I/O ring
has an optical transmitter and receiver. Fiber optic cables connect
transmitters to receivers to form the I/O ring. Refer to Appendix A for
additional information on fiber optic cables and connectors.
