[c-nsp] Upgrading to 40G

[Pshem Kowalczyk]

Hi,

We just started planning to upgrade our 10G (and nx10G) links to 40G
(on ASR9k). Quick scan through Cisco website revealed that there are
no 40km optics available from Cisco. That threw a big spanner into the
works as we have a bunch of links definitely over LR budgets.

So the question is - how do you do 40G in metro areas? Deploy some
sort of amplifiers? Go through DWDM or OTN devices?

kind regards
