Mitsubishi Mnet transmission cable question

[Gaowa]

I would like to ask, can I use control cable -Belden 8760 to connect between outdoor unit and Mnet?

No
Cable size is too small at 0.8mm.

Mitsubishi specification is 2 core screen 1.25mm.
In UK this is non standard size so we use 1.5mm.

If you use smaller section cable you can get all sorts of communication problems & end up replacing it all with the correct type cable.
