GBIC Type and Hardware/Software Support

Measure cable plant losses with a 1550 nm light source and verify this to be within

budget. When calculating the maximum distance attainable using optical cable with a

specified loss per kilometer (for example 0.25 dB/km), Extreme Networks recommends

that 3 dB of the total budget be reserved for losses induced by cable splices/connectors

and operating margin. Thus, 18 dB remains available for cable induced attenuation.

A minimum attenuation of 3 dB is required to prevent saturation of the receiver.
