Cisco GLC-SX-MM compatible SFP

This StarTech.com SFP module is a direct replacement for the Cisco GLC-SX-MM transceiver. It delivers 1 Gbps Gigabit Ethernet connectivity over multimode fibre for network administrators upgrading or repairing Cisco switches and routers.

Pre-installation checks

Verify that your switch or router accepts uncoded SFP modules and has an available LC duplex port. Confirm the link budget matches the 850 nm wavelength and that the multimode fibre run does not exceed 550 m.

Bundled value

The module ships with a lifetime warranty on the transceiver itself and access to StarTech.com technical advisors five days a week. Using this MSA-compliant optic does not void the original equipment manufacturer support agreement on your host device.

Questions about this item

Does the module ship with a duplex LC patch cable or must I buy one separately?

Only the transceiver is included; a duplex LC multimode patch cable is required to complete the link and must be purchased separately.

When should I choose this 850 nm SX module instead of a longer-reach option?

Choose this module for links up to 550 m over multimode fibre; longer distances need a different wavelength.

What does the 1.25 Gbps rate mean once the module is installed in a switch?

The module negotiates at 1 Gbps full-duplex per IEEE 802.3z and the 1.25 Gbps line rate covers 8b/10b encoding overhead.
