Hi Saku,

I forgot to mention, it also depends how "out" of band your OOB needs
to be. We use Ciena 6500s for our DWDM infrastructure and they have a
wayside channel (like various DWDM vendors), so it's a separate
channel over the same physical fibre. For anything except a fibre cut
it seems to work.

Cheers,
James.
