Cisco 1000BASE-LX/LH SFP Transceiver Module
Brand: Cisco · SKU: GLC-LH-SM-RF · MPN: GLC-LH-SM · Category: Networking
The Cisco GLC-LH-SM is a Duplex SFP transceiver for optical communications, designed for 1000BASE-LX/LH Ethernet applications. It operates at a 1310nm wavelength and is rated for distances up to 10km over Single-Mode Fiber (SMF), and up to 550m over Multimode Fiber (MMF). It is a hot-swappable input/output device that plugs into a Gigabit Ethernet port/slot, linking the port with the fiber-optic network. The module complies with the IEEE 802.3z 1000BaseLX standard. While the SKU searched was GLC-LH-SM-RF, the extracted data is for the highly similar GLC-LH-SM, which is the common Cisco part number for this specification. Some compatible third-party modules may use different suffix codes like '-RF' for specific product lines or configurations, but the core specs align with GLC-LH-SM.
