Having bought their 10G modules many times and these 40G modules are also satisfactory. Really plug and play. The whole connection is quite easy and stable. I have nothing to complain about. My account manager has been explained very clearly. I trust their team very much.

Worked as expected. Great price and our Cisco switch accepted it without issue. In general, I do believe quality comes at a price. But FS assures me of their high product performance. I bought so many without a problem. So I believe it's absolutely possible to get good quality at a reasonable price. FS has become my must-go place for optics needs.

We planned to upgrade the existing 10G to 40G as our business grew. The 40G was deployed in our data center, and we wanted it to go to 10G. We sent a draft of our link demand to FS team. They were extremely professional and went above and beyond to resolve my issue. A refined connection diagram was the best reply, and the related transmission rate and explanation were noted alongside each link. According to their design, the whole link was: 40G module #36440 - MTP to 4x LC cables - FHD LC fiber adapters - LC fiber. Finally, we made the order of 40G modules, FHD adapters, MTP breakout cables. The items came in a big box. We plugged the modules on our devices, the LED lights on the devices turned on, and dropped 0 packets.
