This DCM is made in high quality, very suitable for our long haul point-to-multipoint systems. We use it together with the EDFA to maintain signal quality. The services staff is friendly and paitent to answer my questions, and the delivery is also quickly. Thanks.
It was impressive, purchased a product over a live chat and delivered it to my company on the same day. Saved time and cost. Really fast service and postage, very happy. If there is any need, will buy here again.
It makes a considerable difference, the better quality components you use with it...the more difference it makes. That's what I want to say after deploy the dispersion compensation module in our systems.
Having caculate the singal loss for our new networks, our techinical staff think we'd better use a dispersion compensation module. Recommended by a cooperate partner, I bought sereral pcs from FS, products looks very nice, if no problems occur, would buy more in the future.
