ZX en LX-70 zijn de zelfde soort GBIC .. En wij hanteren ook de Cisco GBIC's.
Ze werken prima.

Cisco 1000BASE-ZX GBIC
The Cisco 1000BASE-ZX GBIC (WS-G5487) operates on ordinary single-mode fiber
optic link spans up to 43.4 miles (70 km) long. Link spans of up to 62 miles
(100 km) are possible using premium single-mode fiber or dispersion shifted
single-mode fiber. The GBIC provides an optical link budget of 23 dB-the
precise link span length will depend on multiple factors such as fiber
quality, number of splices, and connectors.

Let wel ff op : 

When shorter distances of single-mode fiber are used, it might be necessary
to insert an in-line optical attenuator in the link to avoid overloading the
receiver:

A 5-dB or 10-dB inline optical attenuator should be inserted between the
fiber-optic cable plant and the receiving port on the Cisco 1000BASE-ZX GBIC
at each end of the link whenever the fiber-optic cable span is less than 15.5
miles (25 km). 


Met vriendelijke groeten,
