GLC-LH-SMD Overview
Cisco GLC-LH-SMD 1000BASE-LX/LH SFP is made for Both Multimode and Single-Mode
Fibers.The 1000BASE-LX/LH SFP, compatible with the IEEE 802.3z 1000BASE-LX
standard, operates on standard single-mode fiber-optic link spans of up to 10 km and up to
550 m on any multimode fibers. When used over legacy multimode fiber type, the transmitter
should be coupled through a mode conditioning patch cable. 1300-nm wavelength, extended
operating temperature range and DOM support, dual LC/PC connector.
