 describes standards, connectors, cabling, and distance for the Model 

1000BASE-SX GBIC.

The Model 1000BASE-LX GBIC provides 1000BASE-LX (1300 nm, 
wavelength, Gigabit Ethernet) connectivity using SC duplex fiber connectors. The 
long wavelength optical transceivers used in the LX model provide variable 
distance ranges using both multimode and single-mode fiber optic cabling. The 
Model 1000BASE-LX GBIC supports full-duplex operation only

.
