Your industrial switch is in a plant, a substation, or a warehouse where temps swing hard and a standard SFP module won't hold up. The TP-Link ISM311LM is built for that. Multi-mode 1000Base-SX over LC fibre. Hot-pluggable — swap it in without powering down the switch. DDM means you check link health from your NMS, not by crawling under a rack at 6am. Runs -40°C to 85°C. SFP-MSA compliant. Three-year warranty. Add to cart and get your link back up
