Comment on Can I attach a 10GBase-LR to QSFP-40G-LR4 (CWDM)?

No the 10LR have a to wide of a bandwidth, so it will interference the other channels.
If the switch support QSPF breakout, a CWDM-10LR may work.
but it cheaper to by
Then to by 1 CWDM 10G.

Yes I am aware of that solution. I should have clarified the goal of the exercise. I’m trying to work out if I can make an easily interoperable system where a singlemode fiber wall jack fed from a 40G switch can act as a both a 10G or 40G port as needed. I am using singlemode as I want to avoid using MTP multimode cable seeing how much more expensive it is than simple lc-lc singlemode.

I understand the use case.
I stand by it is easy to get right, if optic is changing for the difference use cases.
QSPF is not build to be hotplug in that manner.
