Cisco GLC-LX-SM-RGD Optical Module Transceiver 1000Mbps Single Mode Rugged SFP
1 . Overview:
The 1000BASE-LX/LH SFP, compatible with the IEEE 802.3z 1000BASE-LX standard, operates on standard single-mode fiber-optic link spans on any multimode fibers. When used over legacy multimode fiber type, the transmitter should be coupled through a mode conditioning patch cable.
Table 1 shows the GLC-LX-SM-RGD (1000BASE-LX/LH) specifications.
