Connecting Optical Cables,
CAUTION:
High power density exists on fiber when optical power is present. To avoid
microscopic damage to fiber mating surfaces, turn off optical power before
making or breaking optical connections.
1. After cleaning the end of the fiber, connect the optical output cable(s) to the
top connector(s).
2. After cleaning the end of the fiber, attach the optical cable from the optical
source to the input connector (bottom) of the module. This is the optical input
connection.
3. Route the output cable(s) to the appropriate destination.
