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
