You've got an SFP slot on your Teltonika switch but the far end is a copper run, not fibre. Instead of bolting a media converter to the rack and eating up a U of space, this module does the job in one plug. RJ45 output, 1.25 Gbps, straight into the SFP cage. Patch a CAT cable, link's live, done. Add to cart and it leaves our shelf
