StarTech.com Cisco SFP-10G-LR Comp. SFP+ Module - 10GBASE-LR - 10GE Gigabit Ethernet SFP+ 10GbE Single Mode Fiber SMF Optic Transceiver

The StarTech.com SFP10GLRST is a Cisco SFP-10G-LR-compatible 10GbE SFP+ optical transceiver for network administrators connecting compatible switches or routers over single-mode fiber at distances up to 10 km.

Recommended For

• Network administrators replacing a failed optic or adding a 10GbE link in a Cisco switch or router that supports the SFP-10G-LR standard.
• IT teams connecting network segments across a campus or between buildings over existing single-mode fiber, where a 10GbE LR link is appropriate.
• Teams with MSA-compatible SFP+ equipment that accepts uncoded modules, looking for a Cisco-compatible 10GBASE-LR optic; check the host device’s compatibility requirements before deployment.
• Homelab operators linking SFP+ switches or servers over single-mode fiber who need an optical 10GbE connection rather than a short-reach DAC cable.

Real-World Use Scenarios

• Link network switches in separate buildings or distant wiring closets over installed single-mode fiber. With compatible 10GBASE-LR optics at both ends, the fiber can provide a 10GbE connection for extending the network between locations, within the supported link budget.
• Connect switches across a campus or between network sites where the fiber path is longer than a typical in-rack connection. On compatible single-mode fiber and supported equipment, this module can establish a 10GbE link over a path of up to 10 km.
• Uplink a remote switch to a core switch over single-mode fiber when extending a network to another floor, closet, or building. This gives the remote segment a 10GbE fiber connection, provided both endpoints and the fiber path are compatible.
• Replace a failed or damaged compatible SFP+ optic in a Cisco switch or router. Because the module is hot-swappable, an administrator can replace the transceiver without removing the network device from service, though the affected link will be interrupted during the replacement.
• Monitor a fiber link from network-management tools during routine operations or troubleshooting. Where the host equipment supports the module’s DDM readings, administrators can check reported transceiver status alongside other network diagnostics.
