Low cost WDM gear

What others vendors do you using? Here in Brazil only PADTEC have this passive solution... Some days ago Digitel contact me to show your multiplex solution... Is a active solution...
We import this from fiberstore, but i don't know others vendors to buy 10G sfp+ cwdm and this mux/demux...

When using 10km optics, I saw a loss of over 5db  with their passive mux inserted into the path which created a total loss of over -20db which is outside of the tolerances for our equipment with 10km SFP+.  Using another vendors low insertion loss mux corrected our issue.  I am sure if you are using an 80km optic, you may be able to tolerate a higher insertion loss to cover < 60km.  I also notice that their CDWM optics averaged about 3db less in power output when compared to other vendors.

The FiberStore gear was a huge disappointment (excessive loss, poor technical support, refusal to issue refund without threatening legal action, etc.). I have had good results from the OSI equipment so far. I run passive muxes for CWDM (8 - 16 channels).
