Your Teltonika switch's got an open SFP slot and the far end is waiting on a link that just won't come up. You need a short-range transceiver that slots in and talks at 1.25 Gbps without a compatibility headache. This is it. Drop it into the cage, patch your fibre, the link lights up green. No guessing whether the module matches your port. Add to cart and it's heading your way
