FS.com website is great ! It sparks many ideas. If I have any questions, I'll be sure to reach out.

Thank you for the swift international shipping, seamless order process, and excellent customer service. Much appreciated!

We got them and have them in place. I have 1 customer using the 100gb they wanted and seems to be working fine.

To be honest, FS is new for us, and it's the first time that I cooperated with FS, but I was impressed by the fast shipping and great service. After testing, it works so great, so I purchased other devices that I need in my connection program, I'm pleased with the FS products and their excellent service, and will have more cooperation with FS in the future.

After consultation of tech, I choose this MUX for its Exp port, so it can meet my needs for expansion and upgrade. Hope it works well in the future. Pretty good.

Nice DWDM Mux Demux, beautiful looks, and the product is well-packed inside the carton, it ensures my product is well protected. The mux is perfectly applied in my transmission link.
