I have received the package and put some of the optical transceivers to use. The 40G and 100G modules are working as expected and we don’t have any issues at the moment. We are very happy with the quality of your product.

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.
