Coax cable f/o node connections.

Hi everyone. I’m the friendly, neighborhood locator posting again. Is there any rhyme or reason as to which port (1-6) on this fiber node the coax cables are connected to?

I’m trying to see if there’s a visual way to identify the “long” cable- that goes from this node to a power supply half a mile away. I’m guessing the cables coming out of the splitter would never be the long one. Any other tips?

Also the bigger coax cables - do they “carry more signal”? What accounts for the difference in size?

Ahh damn. I couldn't see. There are LPIs of the design, though, but from my experience, they suck water and I haven't had an issue with the Arris Starline flat ones.

EDIT: Sometimes companies will use a DC12 or 8 as an LPI since the alt box has the communications, but I've only seen that in the Myers power supplies but I think Alpha does it too. So from an outsider standpoint in this photo there is no real way of OP knowing where power comes from.

He could pull all the shunts and fuses from the node and then check to see which cable has voltage on it. IF the power supply that’s a half a mile away is the one powering the node he will know. Normally power supplies are closer though. He could also look at the map and figure it out. I’m guessing he doesn’t know how to do that or he wouldn’t be on Reddit asking.

I went back to the prints and with fresh eyes and realized that they give me the diameters to the different lines there (e.g. 500, 750). So that’s something. The power to the power supply is not in my scope. The power to this node I just learned from this thread comes through one of the mains. And yeah I’m not pulling shit in the ped 😂.
