Table 50 describes standards, connectors, cabling, and distance for the Model
1000BASE-SX GBIC.
1000BASE-LX
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
.
