Seems there is no option here. The QSFP-40G/E-LR4 doesn't have an MPO
connector like its' SR4 counterpart, so there is no MPO break-away

Correct, LR4 is 4 10G CWDM waves over a single fiber
Traditionally most people aren't using those for long reach applications just
higher top of rack density, or within the same datacenter. But now switches
are starting to come with more and more qsfp+ ports.
Good news is optics vendors like Avago, Finisar, etc. are making what you want
Thanks for the heads up on a 4x10 sm breakout, Phil.
Do you happen to have a link for more info? I can't seem to find it in any
online literature, or http://finisar.com/products/optical-modules/QSFP
Probably something I will have to call and ask for. :-)

Yes its possible. No idea if Cisco offer it but certainly other vendors do.
Its not a IEEE 'standard' but it certainly exists,

I seem to have discovered that the QSFP+ standard for 10 gig is not flexible
for long-haul applications.
I am deploying a couple Nexus 6004's (mixed 40gig and 10gig) for various
distances but can't seem
