I think it's pretty much safe to say that on a 10G wavelength, buying it
as protected on the same fiber route, same glass path is a total waste
of money.  (at least for a trans-Atlantic circuit).  That's some
seriously expensive electronics protection.  For that cost, it'd be
cheaper to hire people to sit and at the box to replace cards when/if
something happens electronically.  ;-)

If you unplug it fast enough, anything is hot swappable!
