Hey,

So this has probably been asked before but its 4:30am and I can barely keep my eyes open, however... I wish to get a 2nd ONT installed, as I have someone moving into our home downstairs. We already have one existing ONT upstairs and they wish for their own separate connection. What would the price look like considering the conduit is already there, just needs to run a new fibre cable down and drill a few holes (installation wise).

I've looked around the net and seen people talking $150-300 and the absurd $1000's of dollars.

Any ideas would be greatly appreciated.

Surely it’s easier to just run Cat6(5e) cabling from the 2nd port of your ONT, no?

freitasm:

A cable from the second ONT port is completely independent from your primary connection.

It would be a separate service, going directly to their router and even on a different ISP if they want.

It would not interfere with your connection.

Tjey wpuld have to be clear when connecting that this is on the second port. If the ISP doesn't have this on the signup form, try a different one. Can't stress this enough.

As ~~the~~ a resident Chorus guy, I can confirm that the above is correct. There is no negative speed affect from having 2 connections on the same ONT on separate ports because Chorus runs a 100% uncongested network. So it's entirely feasible to have 2 x ports on an ONT both connected with 900/500Mbps services and you'd get full throughput on both of them at all times*.

Option 2: You can order a second ONT installation (free) which uses the spare fibre strand allocated for your address, but you may be responsible for providing a cable pathway between the primary ONT and secondary ONT locations (or between the external termination point and the secondary ONT location). Note that if the "our home downstairs" in your original post actually means a fully separate & self contained dwelling (eg with a separate power meter and letterbox), then the additional ONT installation may be refused and you'd then be referred to Option 3.

Option 3: If the location of the extra ONT is clearly a separate dwelling, then Infill Build will be required to provide an additional & completely separate connection from the street. This is chargeable and is around $1500 off the top of my head.

All of the above info is based on the assumption you are in a Chorus fibre area.

[EDIT: adding the * in my first paragraph as I realised I didn't account for one variable Chorus does not control - the RSP's handover management. When RSP handover points are near or at capacity, this can negatively affect subscriber speeds, however generally speaking most RSPs are pretty good at proactively monitoring their handover loads/capacities, but it's worth calling out regardless...]

The views expressed by me are not necessarily those of my employer Chorus NZ Ltd

These discussions about - Can you max everything out with zero impact vs. Can I order these services and use them normally - are always interesting.
The later of course, being true.
You can put 4x 900/500 services on an ONT and use them. It is unlikely you would notice any kind of user experience issues across those services when they are used in a normal way.

I also don't think I've seen an ONT in the wild with 3 or 4 900/500's on it (I'm sure they exist, but I've never personally seen one) - well, not outside of test services or someone looking for RSP redundancy...

Way off topic now tho :-D
The OP can get a second ONT or use a second port, the decision is up to them based on their scenario and what they are/aren't willing to pay.
