Our company has bought FS fiber cables and patch panels before. They performed well. So we decided to try FS modules when our old ones had been broken.
Ordered these to connect two Cisco switches with fiber in a building to building run. We plugged some of them on our new hardware, and others on the old switches. The switches can recognize the modules without issue. All could run well with the hardware. They function like our old original modules, really good.
