The StarTech.com SFPGLCLHSMST is a hot-pluggable, Cisco GLC-LH-SM-compatible 1000BASE-LX/LH fiber transceiver for network administrators connecting compatible switches or routers over Gigabit Ethernet, with reach up to 10 km on single-mode fiber or 550 m on multimode fiber.

Recommended For

  • Network administrators connecting Cisco switches or routers over single-mode duplex fiber who need a 1GbE link across a campus, between buildings, or to a remote network segment within the module’s 10 km reach.
  • IT teams replacing a failed Cisco GLC-LH-SM-compatible optic in a supported switch or router, where hot-swappable 1GbE fiber connectivity is the goal.
  • Network installers reusing compatible LC-terminated multimode fiber for a 1GbE LX/LH link, provided the fiber type, link distance, and any mode-conditioning requirements are checked.
  • IT teams using MSA-compliant switches that accept compatible, uncoded SFP modules and need a 1310 nm, LC-duplex fiber transceiver for a 1GbE link.

Real-World Use Scenarios

  • Link switches in separate buildings over an existing single-mode fiber run—for example, between a main building and a detached office. The connection can extend the LAN at Gigabit speeds over distances up to 10 km, provided the far-end optic and switch are compatible.
  • Connect a home or small-business network to a switch in a garage, workshop, or outbuilding. Community users describe this kind of switch-to-switch fiber link for detached spaces; this module is suited to setups where 1 Gbps is sufficient and the fiber and optics match at both ends.
  • Add a fiber uplink between network closets when a copper run is unsuitable or the closets are far apart. With compatible 1000BASE-LX/LH equipment and single-mode fiber, the link can carry network traffic between switches over a run of up to 10 km.
  • Add a fiber connection to a compatible Cisco switch during a network expansion or equipment replacement. The module is designed as a GLC-LH-SM-compatible, hot-pluggable optic; verify the switch supports the module and use a matching link standard at the other end.
