Siempre que lo he requerido la atención es muy buena y el servicio de entrega también cumple con mis espectativas.

Worked perfectly

I purchased transceivers from FS previously. I can give you the feedback now. They are good and comparable with the original. FS is also recommended by service providers. FS has a good name.

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.

I’m the technical manager. Your products are great. They appear to be working fine. At the moment we are expecting a long trial, nevertheless, during the first setup, the SFP modules seem to have the same characteristics as the original Huawei ones.

The box of transceivers arrived today and if these work, as well as the reviews, say they do, and prices remain competitive, I don't think there will be a problem convincing people to purchase the product.
