Ubiquity has their new SFP's on the market at a good price. And they have SFP's with BiDi. Has anyone had the opportunity to test these on a CCR/hAP? I'm particularly interested in the 1Gb variant, UF-SM-1G-S.

Current SFP modules price on the market is much lower than before, especially 3-rd party optics. I have bought ubnt devices, but never tried optical modules, fs,com is the only place I got transceivers.

No, I haven't used the Ubnt modules, I always purchase optical modules from fs.com, their 1G SFP modules are around $6.
In this situation, you can order the https://www.fs.com/c/customized-sfp-2985 based on your switch brand.

I have UF-SM-1G-S (3km BiDi) working flawless on my CCR1009-7G-1C-1S+ in the combo port connected to an old gen. RB260GSP.
It does NOT work in the SFP+ slot though (module is recognized, but no link).
