CAUTION
When shorter lengths of single mode fiber cable are used, there is
a risk of overloading the receiver. It may be necessary to insert
an in-line optical attenuator in the link to prevent overloading, as
follows:
• Insert a 10 dB in-line optical attenuator between the
fiber optic cable plant and the receiving port on the
1000BASE-ZX GBIC, at each end of the link, if the fiber
optic cable span is less than 25 km.
• Insert a 5 dB in-line optical attenuator between the
fiber optic cable plant and the receiving port on the
1000BASE-ZX GBIC, at each end of the link, if the fiber
optic cable span is less than 50 km.
