Thanks for the tip. 👍

I mean I know that !homelabsales@lemmy.world exists but including my post there are two submissions. I guess I was wondering if there was a more active community that I missed. So far things have been really inactive.

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 depending on what ethernet card the client is using. 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.

Yes. There is also an adapter that would allow me to use a SFP+ in a QSFP+ port. But I’m trying to work out if I can make an easily interoperable system where a wall jack fed from a 40G switch can act as a both a 10G or 40G port as needed. Hence the question.

QSFP+ to SFP+: MTP/MPO-LC Breakout Cable

This is almost the setup I’m looking for. Except example is using MMF. I want to know is this setup can be done to one SFP over SMF.
