General
Total system budget
Total optical system budget for the SX mini-GBIC is 11.5 dB. Extreme Networks recommends that 3 dB
of the total budget be reserved for losses induced by cable splices, connectors, and operating margin.
While 8.5 dB 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.
LX Mini-GBIC Specifications
