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.
