Don't fully understand why, but I suspect that even though 100G is still relatively expensive, it's still less expensive than 10x 10G DWDM LH.  This fact is driving the take up on 100G, not just the higher data rates etc.  If you're leasing pairs on a long haul system (as is possible in, say, the USA) then the data rates are important as you don't want to lease another pair and have to put amplifiers in the huts along the path as it adds considerably to the cost, where as AU has a very different market arrangement with just a few players.

That's interesting to hear - in the (albeit limited) space we play (intra-DC, minimal amplification/re-gen, 70-80% of customers under 80km), this tipping point hasn't really occurred yet.

Spectrally it's 4 lambdas vs. 10 so the amplification difference is marginal in these shorter hauls, but it's the 100G transponders that still seem quite astronomical compared to the standard 10G transponder/dense-wave XFP combo.
