I concur. I have also used CWDM and DWDM optics and they are fine. I have had one QSFP+ optic go bad. On Mon, Feb 18, 2019 at 07:47:10PM +0000, Brian R wrote:
Samir,
I have purchased over a thousand SFPs from Fiber Store. I can recall less than 5 having problems when we received them (not all even DOA) and I know less than 10 dead even after deployment. Some we have ad running for 4+ years. We have done very little with their SFP+ equipment, really only testing and a few lower priority links. The only downside to the SFPs that we found was the variance of power. Say an Adtran, Cisco, Juniper, HP SFP is rated from -3dB to -8 db (all units I have used them with), the equivalent FS direct SFP we have seen as hot as 3dB and as weak as -15dB. These extremes are fairly rare but we have still seen them. Distribution (approximate): 80% SM single fiber SFPs (mostly 10km - 40km, some 60km & 80km) 7% 1Gb Copper 5% MM SFPs 5% SM dual fiber SFPs 3% others (SFP+, GPON, testing, etc)
I have not used them for any DWDM applications and only used them a few times on an older CWDM link that used standard SFPs into a MUX. This was not over great distances (less than 40 miles). With WDM SFP power consistency was important so we did not play much with it, granted most of the SFPs I am purchasing are in the $10-$25 range so take the extremes with a grain of salt.
Their sales has always been very responsive and helpful. The support/engineering, the few times I worked with them, were helpful but the language barrier was harder here.

Hello All,
Does anybody have experience with fs.com<http://fs.com dwdm equipment in their production environment? Are you they working without any issue? How's their warranty support if the issue arises?
Thanks in advance for all the answers and help.
