I just got these but so far they work great on my Juniper Switches. I was a little worried about using off brand SFP transceivers but these work fine.
We need to build a network between two sites. And the distance between the two sites is about 100km. A lot of sites between them are needed to be connected to this network. To build a DWDM network is the best solution for us. We emailed them our design of the network and they also offer us suggestions. This C21 DWDM SFP+ module can only support up to 80km in fiber optic network. Thus, we also added an EDFA to enhance the signal. The network is running well with these products from fs.com. Coco helped us a lot. Thanks a lot!
Very pleased with the bundle order. Transceiver works great on the switch.
