In reply to a post by Eeeps:

Does anyone have any real figures (measurements) for the power consumption of ONTs?

I assume that if these are XGS-PON versions then there is a significant increase in the power required.

I remember some years ago seeing a 10Gb/s ethernet card fitted to a server and was surprised to see a large heatsink attached to it.

Measured some years ago a bog standard Huawei GPON and it was very low - less than 3 watts. If memory serves, closer to 1-2 watts in steady state passing traffic. I wouldn’t expect an XGSPON version to pull more than 5 to 7 watts, even with a thirsty-ish 2.5/5/10G copper port hanging off the back end….
