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

Since I am in the middle of doing something similar, I will share my observations. CWDM Advantage:- Passive CWDM Muxes are less expensive than the DWDM counterparts. Short Range optics (CWDM) are favorable priced Long Range optics are not so favorably priced. ( I guess
