1000BASE-SX (LC Type) specifications
The Model 1000BASE-SX SFP provides 1000BASE-SX (850 nm, short
wavelength, Gigabit Ethernet) connectivity using LC duplex multimode fiber
connectors. The Model 1000BASE-SX SFP supports full-duplex operation only.
Table 159 describes standards, connectors, cabling, and distance for the Model
1000BASE-SX SFP.
1000BASE-LX (LC Type) specifications
The Model 1000BASE-LX SFP provides 1000BASE-LX (1310 nm, long
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 supports full-duplex operation only.
