The robust build and exceptional performance of FS modules have truly boosted my productivity.

When it comes to reliable and efficient switching, FS modules are second to none.

I really appreciate your help and the high-quality products FS provides.

Good news! I got the parcel today and all is well! I’m officially operating at 25G! You’ve got some fantastic products and unbeatable customer service.

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

I just received the shipment, and the transceiver modules worked right out of the box.
Thanks for good service and fast handling.

Scalability is the name of the game with FS modules, making them an obvious choice.

FS's cost-effective approach to network management is a game-changer.

I didn’t recognize this brand so at the very first beginning, I hesitated. But I was pleased that they had good quality and worked so well on the sfp28 ports of my cisco switches.

We have been using the Cisco compatible 25G ER modules for the last 4 months to connect two Cisco switches via LC fiber optic patch cables. They worked flawlessly. When we inserted them into the SFP28 ports, they were recognized immediately by the switches and allowed us to configure the interface settings as we expected. No packet errors or interface issues. Perfect modules for us!
