Connecting the Interface Assembly to the Fiber Optic Ring
Fiber optic connection to the keyboard on the removable front panel is
made through the interface assembly. Table 9A.F shows the connectors
used to make the fiber optic connections to the I/O ring. Each interface
assembly 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 page 7B-1 for additional information on fiber optic
cables and connectors.
