Recognise this power connector?

Hi Team

Just curious as to whether anyone recognises the bottom power connector in this image. I initially thought it was for an ONT, but the top connector in the photo is from my ONT which says on the front it is a Model Type 200. From the side the connectors look the same, but the 'pin' layout is obviously different. Possibly an older model ONT that I've not come across?

Cheers
