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.
