Product information

Description

Cisco GLC-SX-MM-RFB is a multimode SFP transceiver that operates at 850 nm and uses an LC connector for duplex fiber links. The module is compatible with standard SFP ports and is intended for short-range multimode fiber connections in data center and enterprise network environments. It supports hot-swap installation and is designed for uplinks on switches and routers where reliable, low-cost multimode optic connectivity is required.

Advantages

The Cisco multimode SFP transceiver GLC-SX-MM-RFB provides interoperability with SFP-standard ports and maintains stable optical performance at 850 nm for short-range links. Its LC connector and compact SFP form factor allow straightforward replacement and installation without powering down equipment. The transceiver is manufactured to Cisco specifications for physical compatibility and basic optical parameter consistency, facilitating predictable integration with existing multimode fiber infrastructures.

Suitable for

  • Short-range multimode fiber uplinks between switches and routers
  • Data center short-distance connections and patch panels
  • Enterprise network segments using 850 nm multimode optics
  • Hot-swap module replacement in SFP-compatible equipment

How to use

Verify that the target device supports standard SFP transceivers and that the multimode fiber and LC connectors match the transceiver specifications. With the host equipment powered on or off according to the device manual, insert the GLC-SX-MM-RFB into an SFP port until it clicks into place. Connect LC duplex multimode patch cables to the transceiver ports, ensuring correct TX/RX alignment. After physical installation, confirm link status and interface configuration on the switch or router management interface and adjust speed/duplex settings if necessary.

Usage recommendations

Use OM2/OM3/OM4 multimode fiber that meets the link distance requirements for 850 nm optics; keep connectors clean and inspect LC ferrules before connection. Observe ESD precautions when handling the SFP module and follow the host device vendor guidelines for supported transceiver firmware or compatibility notes.
