Finally, here are all the bits.

No thermal interface in this module, which was a little unexpected. If I remember correctly, the GPON modules I've opened had it... 80km is definately further, but perhaps 100Mbit/s is the key factor here for power dissipation.

Look at the laser weld marks on the TOSA!

@attie ah c’mon you’re not going to take those apart?

@attie do I really only count two pins on the TOSA?? I guess they must be doing direct modulation on the laser.

@psistarpsiii No, it's 4x pins total - 2x pins on each side of the PCB.

@psistarpsiii 😂 I'd love to, but sadly these need to stay operational! 😭
