We did this at $prev_job (actually a national ring, but including Docklands and Williams House), but as you found, it's not widely sold. The challenge is that you're piggy-backing on someone else's optical network, and depending on their amplification and (potentially) regeneration platforms. To not affect the other uses of the optical spectrum, they will need to work with you to balance optical levels on different wavelengths, so as to not unbalance their amps, etc. You're probably better off finding smaller players who have taken leases on dark fibre and running DMDM on that path, and see if they'll work with you. For example, I believe Commsworld (Hi Charlie!) have this path and are running a DWDM on it. Simon
