Distance 70 km

Receiver Characteristics

Wavelength 1200 to 1550 nm

Minimum receiver sensitivity -22 dBm

Maximum input power -3 dBm

Note: 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.
