NBN - HFC Tech Question

Touched on this a few weeks back, still in the dark.

I can’t find a specified separation of cabling for an HFC install to the terminating point. Got the conduit spec and GPO needs, that’s easy.

I want to terminate on a narrow brick nib wall 2800 high. I can either chase up for power and down for coax or both down. This would be easier; less patching overall. But the most spacing I could manage is about 120mm between centre lines. With HFC is there any interference from nearby mains power? Logic suggests not, but I’m interested to hear real world stories and maybe see a reference to the applicable standard or guide.

Hi. The HFC setup is coax cable into your home, the NBN "connection point" will be inside your house next to your modem. It wont need any power to the external NBN utility point. See here https://www.nbnco.com.au/content/dam..._Guide_HFC.pdf . Cheers MD

Hi Michael,

It’s about my chosen location in the house (central and high up). The separation between my conduit for the coax and my conduit for twin and earth, if there is a recommended or mandated minimum distance.

Hi. The NBN installer will run and terminate the coax from the utility point to what he considers is a suitable place. What they call a suitable place is normally a position inside the house against an external wall on the lower level near the run coming in from the street and near an existing GPO. If you have an alternative location with easy access and power the NBN bloke should be able to run the coax to where you want it. Cheers MD
