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

All the goods deliveryed on time in good package. The instruction manual is really helpful and I install the eauipment by myself easliy. The FMU housing is an amzaing design because it is convient to add more channels to the Mux&Demux. Perfect!

I know FS.COM from reddit, many customers are talking about this company on there. At first, I purchase some optics and fiber patch cables from them, the performance are good. Good service and fast delivery impressed me a lot. Then I try to buy DWDM Mux Demux for my new project and I find that I made the right choice. They also have this DWDM Mux Demux in stock. It really help me a lot on my new project due to emergency circumstances. Amazing.:)

I could customized all of the exact detail. really enjoy purchasing mux from FS.COM. When I have urgent need, I could purchase those mux that have stock, I can't believe that they could arrange so many stock for mux. When I have specific and special need, I could order this customized mux. The quality is really great as we don't have any quality issue from my first shopping in 2015 till now.

I need to purchase some DWDM Mux for new project, but I didn't find the Channels I need on the website. Fortunately, my Account Manager helped me get the customized channels for my need, really appreciate this customizing service, which helped me a lot. I will buy again if needed.

Everything from the quality of the items to the quality of service has been amazing. Thank you so much.

Received my MUX on time. Keep up the good work. Excellent service.

As always, excellent service and rapid shipping! The Mux i ordered is great.

Bought some fiber cables together with this DWDM Mux/Demux. Everything went well, and I received them on time.

This MUX is looking great when I got it at the first time. Great quality and well made. Insertion loss is satisfied. If need, will come back.
