Table 49 describes standards, connectors, cabling, and distance for the Model
1000BASE-SX SFP GBIC.
1000BASE-LX (LC Type)
The Model 1000BASE-LX SFP SFP GBIC provides 1000BASE-LX (1300 nm,
wavelength, Gigabit Ethernet) connectivity using LC 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 SFP GBIC supports full-duplex operation only
.
Table 50 describes standards, connectors, cabling, and distance for the Model
1000BASE-LX SFP GBIC.
