Worked as expected with connection from non Cisco to Cisco switches. Great transceivers , price unbeatable.

I am familiar FS.com from my previous jobs, you are highly rated with tier 2 and 3 MSOs in states especially for SFP transceivers and fiber optic passives.

Excelente producto y de buena calidad. Llegan en tiempo, sólo que hay que considerar los impuestos a pagar en paquetería.

The SFP I used is working just fine thus far. Ordering process was easy.

The modules arrived quickly and worked perfectly in pre-deployment testing. The deployment should be finished by the end of this week and I foresee no issues.

Product, support, packing all are excellent. I am giving 5/5

We need a Dual fiber Single mode SFP for our Mikrotik Router. Good quality SFP is not available in our place. So, we decide to buy from fs.com. It also gives us good insight about other charges like customs duty etc.

I bought a pair of these FS transcievers in order to replace the existing TP-LINK TL-SM311LS ones in the two TP-LINK MC220L media converters that I use for galvanic isolation before the audio network streamer.

In comparison, the FS transcievers offer more bass, a narrower but deeper sound stage with more focus and better holographic imaging. It is a worthy investment, I'm very happy with the result.

The product is reliable with good build quality.

Works well with Ubiquiti switches.
