We had some troubles in 40G and 100G DACs on MX204 and MX10003. e.g. 40G 
DAC worked in $old versions and suddenly stopped in $newer versions. It 
seems it stopped working when 100G DAC support was officially 
introduced/supported.

Officially they do not support 40G DAC (regardless of type), but 4x10G 
SR or LR Breakouts are supported and do work in our LAB.

Sometimes it can make a difference whether or not the third party optics 
are coded to the correct SKUs. So it may help to play around with 
different codings, i think FS also offers a Box to change the programming?

Juniper has specific SKUs where they support the 4x10G Breakout (e.g. 
QSFPP-4X10GE-LR and SFPP-4X10GE-SR), but so far Breakout also worked 
fine on other parallel optical transceiver we tried.
