How to use

Insert the SFP transceiver into a compatible SFP port on a switch, router or media converter while the host device is powered according to the vendor’s guidelines for hot-pluggable modules. Connect the appropriate multimode fiber patch cable (850 nm) to the module’s optical interface. Confirm link status on the host device and verify speed and duplex settings if required. Handle the transceiver and fiber connectors by the housing; keep dust caps on unused ports and clean connectors before mating.

Recommendations

Use multimode fiber and patch cords rated for 850 nm operation and ensure connector types match the host equipment. Observe ESD precautions when handling the module, store unused modules in anti-static packaging, and follow the equipment manufacturer’s compatibility list to ensure optimal performance.
