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.


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.
