The StarTech.com GLCSXMMDST is a Cisco GLC-SX-MMD-compatible 1000BASE-SX SFP transceiver for network teams connecting Gigabit Ethernet equipment over multimode fiber, with an LC duplex connector and a maximum reach of 550 m.
Recommended For
- Network technicians replacing or adding a 1GbE optic in a Cisco-compatible switch or router with an SFP port, when the device accepts third-party Cisco-compatible modules. A hands-on test found this model was recognized and operated in a Cisco Catalyst 2960G and a Meraki switch.
- IT teams connecting switches or other SFP-equipped network devices over existing duplex multimode fiber, when the link needs Gigabit Ethernet rather than 10GbE. The supported reach depends on the fiber type and link conditions.
- Installers reusing multimode fiber with duplex LC connectors for a short- or medium-reach LAN link, such as between network closets, after confirming the equipment and fiber meet the 1000BASE-SX requirements.
- Network operators who want digital diagnostics from a compatible device to help check optical-link conditions; this module supports DDM/DOM, though availability of readings depends on the host equipment.
