I've bought their DWDM 80km 10gig and they are working beautifully on a couple amplified circuits with both Cisco and Juniper routers. I've also bought gray optics and DACs. The only issue I've noted with some QSFP+ DACs is some kind of programming issue where the serial number is mis-read by some models of our Juniper switches. Another oddity is that each end of some of our DACs have a separate serial number...we just record both in our inventory tracking system.
