Juniper QFX Models - Port Speed Variations

Hi , 

I am trying to achieve the below scenario with a QFX Model. Can't seem to find the right fit.

I need 4 ports of 100G;- 4 ports of 10G and also need few ports of 1G.

Now with the available models, I see one can either mix 1 & 10GE ports, or 10/40/100 GE ports. Can't see any that has the scale from 1GE to 100GE on the same switch.

Is this achievable?

I'm curious as to what Breakout cables mean as i haven't so much time on Optics form factors. Is any close a solution to what I have described? Or rather, what would be most cost efficient solution.
