You've got a TP-Link switch with an empty SFP port and a run of fibre stretching out the back of the building. You need a module that drops in, locks on, and pushes gigabit over single-mode fibre without you hunting for a compatible part number.
The SM311LS is a single-mode MiniGBIC rated to 20 km on 9/125 μm SMF. It slots into any SFP port across the TP-Link range — JetStream switches from the TL-SG2210P up through the TL-SG5428, the T3700G-28TQ, and the MC220L media converter. If you're bridging to an MC210CS over single-mode fibre, it pairs cleanly.
Hot-swappable, so you don't have to pull the switch offline at 6 pm on a Friday to swap modules. Six are on the shelf right now. Add to cart and it's on its way before your next site visit
