Few months ago, we purchased some equipment from M6200 series to use for some 10G wavelengths. We are happy with the deployment of this platform, and we decided to use FS equipment going forward.

We always praise FS quality and superb performance, as well as great customer service.

Since our switches can't directly use WDM SFP+, this OEO is a must. It is the same as that displayed on the website, and also works smoothly after connecting to other devices. Fair prices, the delivery is also very fast. I am very satisfied with it.

I compared several suppliers and finally found that FS's price and features are satisfactory. They asked me about my application scenarios, including link loss, distance, and some others. After that, they provided a diagram for my network solution, also the quotation. Best of all, these thoughtful tech services are totally free! I'll come back for my next project in the second half of the year!

I am impressive with the design. It is easy to install.

There was a little accident with shipment. My account manager resolved it efficiently. The first order went very well. I will definitely buy more through FS.COM.
