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

Good device
I have used several of these and find them to be good quality and easy to install. Never got a bad one...

購入前の質問が多く、カスタマーサービスが辛抱強く答えてくれて、配送プロセスも通知してくれるので安心です。

Great product. The expansion port is very suitable for me, for the possibility of my network capacity increasing in the future.

I have achieved 16-24 x DWDM channels over an existing CWDM link with the help of FS OTN team, perfect!

Arrived as expected, seems to be well made.
