CM4 OPTICAL INTERFACE ADAPTERS
8.3.1
INTRODUCTION
Optical Interface Adapters (OIAs) are used to provide a optical fiber interface between 9508D
terminals in a network. Input and output external timing, and RS-232 communication are also
provided. Figure 8-10 shows the panel view and pinouts of a typical OIA. Table 8-12 summarizes the
characteristics of the various OIAs. These OIAs can only be used with CM4 Modules that support CMI
encoding.
WARNING
YOUR RFL 9508 TERMINAL MAY BE EQUIPPED WITH FIBER OPTIC
INPUT/OUTPUT MODULES THAT HAVE FIBER OPTIC EMITTER HEADS.
FIBER OPTIC EMITTER HEADS USE A LASER LIGHT SOURCE THAT
PRODUCE INVISIBLE RADIATION. FIBER OPTIC COMMUNICATION
SYSTEMS ARE INHERENTLY SAFE IN NORMAL OPERATION BECAUSE ALL
RADIATION IS CONTAINED IN THE SYSTEM. IT IS POSSIBLE DURING
MAINTENANCE TO EXPOSE THE RADIATION BY REMOVING OR BREAKING
THE FIBER. STARING DIRECTLY INTO THE LIGHT BEAM MAY RESULT IN
PERMANENT EYE DAMAGE AND/OR BLINDNESS. NEVER LOOK DIRECTLY
INTO THE LIGHT BEAM AND BE CAREFUL NOT TO SHINE THE LIGHT
AGAINST ANY REFLECTIVE SURFACE.
THE LASER SOURCE IS A CLASS I LASER PRODUCT WHICH COMPLIES
WITH APPLICABLE FDA, OSHA AND ANSI STANDARDS.
If your RFL 9508D
is equipped with a Fiber Optic Module, fiber optic connectors must be connected
to the fiber optic heads on the rear panel of the 9508D
chassis. Type ST series bayonet fiber optic
connectors (or their equivalent) are used with both singlemode and multimode fibers. The exact
mating connector used will depend upon the head that is installed in the fiber optic module, and the
specific optic cable being used.
When connecting fiber optic cables, make sure the connectors are properly aligned before tightening
and then fully tighten them. This will help minimize losses in the connector.
