SFP+ DWDM transceiver module worked successfully on Calix E7. We found by accident a 120km transmission solution advertised on FS website, which took the use of SFP+ DWDM 80km transceiver, preamplifier, output booster. It was exactly what we were looking for in the next project. Copied the whole components by confirming the feasibility, we succeeded in the establishment and operation of the 80km+40km point to point DWDM system.

I've ordered these to replace the previous h3c transceivers and I am happy with the fact that they are an excellent replacement. All the transceivers just worked as soon as they were plugged into the interfaces.

Very nice products. All of my orders were delivered very quickly with nifty and securely sealed packaging. I am quite satisfied that I get a solid 10Gbps link of my switches. To sum up, I am happy I got these modules.

Our new project includes 1G and 10G long-haul interconnect among multiple sites. FS technical guys recommended us to deploy the DWDM and CWDM systems at the same time, and help us solve lots of problems when choosing the suitable products. One of that was, to avoid later network maintenance and upgrade troubles, my boss required to use 10G DWDM H3C transceiver on the 1G port, I was not sure whether it could work or not. The FS guys helped us test the module working status on their switches and offered us the video, no issues of the connection. Thanks. All products have arrived on time, and we will start our project deployment this week.

We plan to build a passive 10G DWDM system in our project to link three sites. FS technicians have formulated a DWDM solution according to our requirements, which contains detailed loss values for each link, as well as DWDM transceivers and List of multiplexer products. Other problems we encountered also gave very professional explanations. Thanks for the patient technical service, we are very satisfied with this purchase.
