I opposed 40GE, but since physics is a lot of the problem here, I think 400GE is favorable over 1TE. Already now we're sitting with platforms with forwarding performance per slot that doesn't really match 100GE nicely, imagine the equivalent problem for 1TE. By the time this is ready, will platforms be at slightly over 1T per slot, perhaps it then makes more sense to have 3x400GE instead of 1x1TE per slot.
1Tb/s per slot is a reality that will be here sooner than many might realize. I think the bonded vs. native argument can come down to optical bandwidth. If you are limited to N number of wavelengths on a segment having faster native interfaces becomes desirable (assuming similar optical bandwidth per unit). -Steve
