Does anyone have any recs for GPON/XGS-PON SFP/SFP+ ONTs-on-a-stick that run cooler than average (say 50-65 °C)?

Speaking of modules that lie about themselves, unifi has an interesting little device called the "SFP Wizard" that can reprogram sfp modules.

I tend to use fs.com optics, but I’ve heard in high rates (100g plus) that flex optic tend to be more reliable

FS has a reprogrammer, called the FS Box. Works well.

fiberstore has them as well, plus you can buy modules, DACS and everything programmed to the vendor of choice, including different vendors on each end

Especially handy for specific Intel NICs where they refuse to link up if the module isn't in the driver-allowed list and those modules are hard to come by

I am in the market for an SFP+ module and was looking at this exact model! The serendipity made me smile. Cheers mate.

why not use fiber directly and use whatever sfp for much cheaper without worry of heat
