You can still run passive optics and do 8 channels for the cheap and do up to 80Gbps that way though.

That is correct. We are building a metro ring now and have quotes from all of the major providers. Ciena gear can handle 100Gbps on a single strand (which even though all of the gear providers say is 200Gbps it is still really only 100Gbps redundant)....but it is still a good size hit against capx costs. We got them down to about $240k with their single chassis redundant boxes. Transmode is playing at the bottom of the list doing 40Gbps redundant for about $150k. We are leaning towards the Adva gear because they are between the two but they are located about 8 miles from us and we like having our vendors in our backyard. ;)
