FluxLight

I have 3 of these, and while they are expensive and I could have bought a whole new switch for the same price, it is convient to add an additional Ethernet port if you need it. I have mine installed in an ubiquity edgerouter 4 and an ubiquity poe switch. No issues with them. On the switch they get pretty toasty; not sure if they are acting as a heat sink or if that is the nature of these ports.

Worked perfect

Purchased these through FluxLight for a customer and they have been extremely happy with them. I will continue to recommend these products.

We use these SFPs exclusively on all our installations. The reliability is critical for us because most of our installs are located in remote areas and we can't afford failure. We have used this SFP (and others from FluxLight) with zero compatibility issues or failures.

Happy customer, great prices
