Somewhat bizarre scenario... (Fiber distance)

Given this 40G/100G topic, I figured I'd bring this up given the topics. I've got a link that is testing out at 29.5db loss @ 1550. Its 107km. I seem to remember a few good solutions for 1Gb/s or 2.5Gb/s that can handle a link like this, but its been a while and I can't seem to remember. I can put a regen in there if I have to, but that or an EDFA both seem like ugly solutions since I just need 1 wave. Shoot me a few suggestions? Thanks in advance, Deepak
