Insert a compatible SFP transceiver into the converter's port, making sure it matches the network's media type and speed. Then, connect one end of the fiber cable to the transceiver and the other to the appropriate port on a switch, router, or another media converter. This allows networks to extend beyond the 100 m copper limit while gaining higher bandwidth and resistance to electromagnetic interference. In the illustrated setup, each LAN links to a. A fiber optic media converter is a networking device that converts data signals from one type of media to another. Protect your devices from lightning strikes and enjoy reliable, high-speed connectivity with the MC220L media converter.
