StarTech.com SFPG1320C Cisco GLC-LH-SMD Compatible SFP Module -1000BASE-LH Fiber Optical Transceiver - SFPG1320C

The StarTech.com SFPG1320C is a Cisco GLC-LH-SMD-compatible, hot-swappable SFP transceiver for single-mode 1000BASE-LH fiber links up to 20 km. It suits network administrators connecting compatible Cisco equipment over long-distance fiber.

Recommended For

• Network administrators replacing a failed Cisco GLC-LH-SMD optic in a compatible switch or router who need a 1GbE fiber link and want a hot-swappable module.
• IT teams connecting separate buildings or remote network segments over single-mode LC fiber where a 1GbE link is sufficient and the run is within the module’s stated 20 km maximum.
• Administrators of compatible Cisco or MSA-compliant equipment who want a 1000BASE-LH optic with DDM for checking transceiver status through supported network-management tools.
• IT staff maintaining Cisco Catalyst or industrial switch deployments, including listed families such as C9300, IE2000, IE3000, and IE4000, who need a Cisco GLC-LH-SMD-compatible replacement optic.

Real-World Use Scenarios

• Link two compatible Cisco switches over an installed single-mode fiber run—for example, between a main equipment room and a remote building—so the remote switch can join the same 1GbE network without a copper run between them.
• Extend a network to a remote segment that already has single-mode fiber, using the SFP in a compatible Cisco switch or router; the connection can carry 1GbE traffic when the fiber path and optic at the other end are compatible.
• Replace a failed or damaged compatible SFP in a Cisco switch or router while keeping the existing fiber connection, avoiding the need to replace the whole device or run new cabling.
• Check a fiber link during troubleshooting or routine monitoring: the module’s DDM support can provide transceiver status to compatible network-management tools, helping an administrator investigate link issues.
• Connect a compatible Cisco device to a fiber-equipped network endpoint or neighboring device when both ends support matching 1GbE optics and the fiber type is appropriate; this is not a direct copper-Ethernet connection.
