Product Info

Industry-standard SFP Transceiver Module

Cisco's industry-standard SFP is a hot-swappable input/output device that plugs into a Gigabit Ethernet port/slot, linking the port with the fiber-optic network. SFPs can be used and interchanged on a wide variety of Cisco products and can be intermixed in combinations of IEEE 802.3z- compliant 1000BaseSX, 1000BaseLX/LH, or 1000BaseZX interfaces on a port-by-port basis.

The Cisco GLC-SX-MM operates on ordinary multi-mode fiber optic link spans of up to 550 m in length.


  • Hot-swappable when deployed, the switch or router does not have to reboot
  • Supports the “pay-as-you-populate” model
  • Interchangeable with other 1000BASE-X SFPs on the same line card
  • Supports the Cisco quality ID feature that enables the switch or router to identify whether or not the SFP is a Cisco qualified SFP
  • Optically interoperable with respective 1000BASE-X Ethernet interfaces on the same link
