What vendors do you recommend for low cost CWDM / DWDM gear? Assume you
have a fiber ring of 50 miles of fiber, and want to have  POPs evenly
spaced around the ring that you want to jump on and off of. Assume you only
have 2 fiber strands to work with, but can obtain two more at an additional
cost. Does 2 vs 4 fibers make a difference? The goal is to be able to offer
multiple 10G connections to clients on the ring. All ethernet/wave no
support for legacy SONET needed. How do you decide between CWDM vs DWDM?

There are so many manufacturers that make transport gear I do not even know
where to begin. Is there a guide to navigating through the big optical
transport vendors? There are over 20 of them, and they all seem to do the
same thing on paper.
