FS's after-sales service is always responsive and satisfies me.

When I didn't know how to use it properly, FS's technical support provided me with timely assistance and solutions. It has been a great shopping experience.

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.

The transmission rate is stable, making it suitable for high-demand environments such as data centers and enterprise networks.
