http://www.ghipsystems.com/en/Products/SFP-en/SFP-en.html - optics with
30dB margins also. I imagine these are fairly widely available from more
local (to you) vendors.

You could send someone to clean all the connectors too ;-)

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.

30dB. Will do more, we've done ~180km (~36dB) with one of those.

Responding to myself. I've tentatively had it lit with an MRV LR2 type 
optic which is xmitting at 0 db (min rated is -2db) which *should* just 
make it... but I was hoping for a solution that wasn't as... "tight".


I'd hate to have someone have to test through a few spares to find a
replacement optic that was "hot" enough.

Thanks.
