When 12016s are on ebay for $12,000, even a low budget "tier 3" can
afford proper routing gear... It's not as if the Internet is still
powered by 7507s! (Well, a large part still is. :-)

I am starting to see some interesting long-distance 2.5Gbps CWDM gear
offered by European manufacturers, with 70km and 100km distance ratings.
This stuff sells for a fraction of the price of equivalent
Nortel/Ciena/Cisco ONS gear. Lots of optics companies are making 70km
rated SFPs in 8 or 16 wavelengths now. So far it only runs at OC-48
speeds, but 10Gbps will be coming soon.
