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.

Just to let you know: we have started using the transceivers today and they work perfectly. I had a lot riding on them and they are just what we needed, so thank you very much.

I haven't tested the FS box yet, but I will use the user guide you sent me. Thank you very much!
