New rule. Share your own data before asking others to share theirs.

IN DC, SP markets 100GE has dominated the market for several years
now, so it rings odd to many at 'more common'. 112G SERDES is shipping
on the electric side, and there is nowhere more mature to go from
100GE POV. The optical side, QSFP112, is really the only thing left to
cost optimise 100GE.
We've had our share of MSA ambiguity issues with 100GE, but today
100GE looks mature to our eyes in failure rates and compatibility. 1GE
is really hard to support and 10GE is becoming problematic, in terms
of hardware procurement.
