Cisco Rugged SFP - SFP (mini-GBIC) transceiver module - GigE - 1000Base-LX, 1000Base-LH - LC/PC - up to 6.2 miles - 1310 nm - for P/N: 4GE-SFP-LC-RF=, GRWIC-D-ES-2S-8PC, GRWIC-D-ES-2S-8PC=, GRWIC-D-ES-6S
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.
