Description for Cisco GLC-LH-SMD 1000BASE-LX/LH SFP Transceiver MMF/SMF
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.
This Figure shows the appearance of GLC-LH-SMD.
The table provides cabling specifications for the SFPs that you install in the Gigabit Ethernet port.
Note that all SFP ports have LC-type connectors, and the minimum cable distance for all SFPs listed (multimode and single-mode fiber) is 6.5 feet (2 m).
