Table 1 describes the specifications for the LX mini-GBIC interface.

Total optical system budget for the LX mini-GBIC is 13.5 dBm. Measure cable plant losses with 
a 1310 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 dBm of the total budget be reserved for losses 
induced by cable splices/connectors and operating margin. Thus, 10.5 dBm remains available 
for cable induced attenuation. There is no minimum attenuation or minimum cable length 
restriction.

Table 2 describes the specifications for the SX mini-GBIC interface.

Total optical system budget for the SX mini-GBIC is 11.5 dBm. Extreme Networks recommends 
that 3 dBm of the total budget be reserved for losses induced by cable splices/connectors and 
operating margin. While 8.5 dBm remains available for cable induced attenuation, the 
1000Base-SX standard specifies supported distances of 275 meters over 62.5 micron multimode 
fiber and 550 meters over 50 micron multimode fiber.  There is no minimum attenuation or 
minimum cable length restriction.
