When shorter distances of single mode fiber are used, it may be necessary to insert an in-line optical
attenuator in the link, to avoid overloading the receiver:
•
A 10 dB in-line optical attenuator should be inserted between the fiber optic cable plant and the
receiving port on the WS-G5487 GBIC at each end of the link whenever the fiber optic cable span
is less than 25 km.
•
A 5 dB in-line optical attenuator should be inserted between the fiber optic cable plant and the
receiving port on the WS-G5487 GBIC at each end of the link whenever the fiber optic cable span
is equal to or greater than 25 km, and less than 50 km.
