Your switch has a free SFP slot, but the copper run to the next floor or building is too long for a reliable 100Mb link. This module solves that without swapping out the switch. Drop the Alloy 100SFP-M02 into any 100Mb SFP port and you get multimode fibre out to 2km over 62.5/125µm MMF. It's hot-swappable — plug it in, pull it out, no reboot window needed. 1310nm VCSEL laser, PIN photodetector, up to 155Mb/s bi-directional throughput. Compliant with SFP MSA and SFF-8472, duplex LC receptacle. Runs on a single +3.3V supply, rated 0° to 70°C. RoHS compliant
