Passive DWDM in Production Service

["Vincent J. Bono" <vbono () 2nplus1 com>]

Hey Everyone,

If anyone is using, in production, passive DWDM muxes / shelves with colored 1GigE or 10GigE optics in standard 
switches or routers drop me a private note?  I'm looking for real world examples for a white paper.

Thanks in Advance,
Vin
