StarTech.com SFPSXMM 10GBASE-SR SFP+ Transceiver Module, 10 Gbps, 550m

The StarTech.com SFPSXMM is a hot-swappable 1000BASE-SX SFP transceiver for adding 1GbE fiber connectivity over multimode fiber, up to 550 meters. It suits network administrators connecting compatible switches, routers, or other network equipment with duplex LC fiber.

Recommended For

• Network admins adding a 1Gbps fiber uplink between a switch and router that support 1000BASE-SX SFP modules and multimode fiber.
• IT teams connecting network equipment across a multimode-fiber run within the module’s supported distance—up to 550 m with 50/125 µm fiber, or 300 m with 62.5/125 µm fiber.
• Technicians replacing a failed or missing 1000BASE-SX SFP in compatible MSA-compliant network equipment, without changing the existing multimode-fiber link.
• Small-business or homelab network builders using an available SFP port for a 1Gbps fiber link between a switch, router, or other compatible network device.

Real-World Use Scenarios

• To connect two switches over an existing multimode fiber run between rooms or wiring closets, install a compatible 1000BASE-SX module at each end; the devices can communicate over a 1GbE fiber link if the fiber, connectors, and port compatibility match.
• When extending a wired network to a remote segment, use the module in an MSA-compatible switch or router with a matching multimode fiber connection; it provides a 1GbE uplink over supported fiber runs.
• When replacing a failed or damaged optic in a compatible switch or router, use this module as a 1000BASE-SX replacement; its hot-pluggable design can help avoid removing the device from service, though the network impact depends on the equipment and link setup.
• When upgrading an older fiber connection between network devices, check the installed fiber type, connector, link distance, and device support before swapping modules; a correct match can bring the link to 1GbE, while a mismatch may prevent the link from coming up.
• For a longer in-building fiber link, use the module where both endpoints support 1000BASE-SX and the multimode fiber meets the run’s requirements; this can connect network equipment across a facility without relying on a copper Ethernet run.
