Connecting Optical Cables
To Connect Cable
Important: It is recommended that all connections be made with the optical power
off. This will reduce the risk of damage to the fiber.
Note: Observe laser safety precautions. Refer to Laser Safety (on page xix) for
additional information.
Follow this procedure to make the optical cable connections for each module to be
installed.
CAUTION:
High power density exists on fiber when optical power is present. To avoid
microscopic damage to fiber mating surfaces, turn off optical power or reduce
power below 15 dBm before making or breaking optical connections.
1
After cleaning the end of the fiber, connect the optical 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.
