I've bought at least 20k in optics from them in the last 2 years, from QSFP DAC, QSFP to 10g breakouts and everything in between and the only thing to fail was 1 QSFP breakout cable. A partner of ours uses their DWDM optics and passive MUXs while I've used their CWDM with no issues.

Subject: DWDM Optics cheaper than CWDM Optics?
fs.com offers DWDM optics that are cheaper than CWDM optics:
CWDM 80km 10G for 600$ http://www.fs.com/c/cisco-cwdm-sfp-plus-2425?70-80km
DWDM 80km 10G for 420$ http://www.fs.com/c/cisco-dwdm-sfp-plus-2485?70-80km
This is significant.
Is this for real? Has anybody bought their DWDM optics?
Going with DWDM and passive Mux/Demux seems to be cheaper nowadays than going with CWDM.
