I was genuinely impressed by the swift shipment of this order and the outstanding level of service we experienced.

I purchased this product because of its price and performance. It proved to be easy to setup and works great.

I've had this chassis running for about a week now and it's been working great. And setup was a breeze.

Ordering from your company has been amazing so far, getting things quickly in a pinch has saved me twice now!

Our project is designing and planning for optical transport networks. Lacking experiences, we decided to pick FS to design for our solution. The professional technical team offered us a complete DWDM solution including a well-organized deployment plan with topologies, specification details, notes, and product lists, very elaborate and helpful. Highly recommended.

Purchased it to accommodate an optical line protection switch that, together with a pluggable optical splitter, composed BIDI OLP. Both main and backup opt line power can be monitored.
