The brand reached out to provide guidance after purchase. Exceeding expectations, the first trial was a success right.

It's a rare find to come across something both affordable and of such high quality. The detailing of FS's packaging is unexpectedly exquisite.

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.

Thanks for the concern, and your always quick and polite responses to orders and questions. I really love your products, quality, prices, and delivery. And especially the perfect guide for ordering exactly what you need.

I have put the two transceivers to work, and they are working well. I’m using these in a personal environment rather than professional, but I will likely be buying more in the near future.

I got the modules. It's works perfectly. Super happy with the whole ordering process.

So far I’ve tested it in switches and it seems to work great.

all good thanks for the attention.
