Hope you had a great weekend. I have received the package and put some of the optical transceivers to use. The 400G 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 just received the shipment, and the transceiver modules worked right out of the box. Thanks for good service and fast handling.

They perform well, and seem to be reliable, and great value.

We can talk, learn from, select, and order from FS non-proprietary components and parts. FS is basically a really good vendor of many suppliers for ground commercial applications.

Very quick shipping and got what i ordered.

We tested the module, it works very well, it is much higher quality than other competing products.
