Little update on this.
While a lot of people reported excellent result with the same FS
model, while we're very confident in FS products, I can get that link
stable...
Here our lab notes so far....

Our 2 Fiberstore QSFPP-40GBASE-LR4.
Connected back to back
With -10db/-12db pads to make sure to not burn them
(still required? we had auto-adjusting 10Gb in the past)
And 0 traffic.

Hi,
Beside Juniper, anyone have some successful experience to share
about a second source of QSFP+-40-LR4?
All the optics tested from our usual rock solid providers ended up
flapping or spamming log message :(
Thank you for your time.
PS: Our QFX5100 VCF Fabric (6) is finally stable with the
preferred release of Junos, TLDR: You cannot get out of the Spine/Leaf
paradigm (contrary to initial documentation which also showed full
mesh and linked routing engines). Also there was an issue with 1
forwarding-options.
