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.
