Can you name optic only available in X2 casing, not XFP? I'd be surprised
to find one.

When I asked years ago in San Jose EBC from BU guy about their love for X2
the simply stated because it's most deployed/common 10GE switch optic in
the market.
I don't know if he was being funny or serious, considering Cisco was (still
is?) at that time shipping most 10GE ethernet ports in the world. So even
if their optic was techno goblins flickering glowsticks in a rave, it would
still be factually true statement.
