Table 48 lists the specifications for the LX mini-GBIC interface.
Measure cable plant losses with a 1310 nm light source and verify this to be within budget. When you
calculate 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 or connectors, and operating margin. There is no minimum system
budget or minimum cable length restriction because the maximum receive power is the same as the
maximum transmit power. There is no minimum attenuation or minimum cable length restriction.
