I/O Interface
Section 10A
10A-54
The connectors used to make the fiber optic connections to the I/O ring are
listed in Table 10A.AM. 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.
The fiber-optic connectors are located under the front door of the 1746I
module for easy access. Run the fiber-optic cables out the bottom of the
1746I module to allow the front door of the module to close after the
cables have been installed.
