[c-nsp] Long range 10G ethernet?

[Frank Bulk]

You generally will save some light if you skip the intermediate patch cords
and splice it through.

A bit of both. :-) I think it's just short of 100 Km in total, but with
several patch cords/ODFs along the way. Some of these can be removed but
removing all would probably make too expensive compared to what we win
by running 10G.

Hadn't thought of the G.709 angle. But since it still requires external
equipment (for a 6500) the amplification path is probably easier.
