I recently upgraded to 2000/2000 internet with MyRepublic [insert BS justification here]

I got to reading after they installed the Nokia ONT and it sounds like you can replace your ONT with a regular SFP module as its not using the same underlying fiber technology as regular 950/450 plans, If you inspect the Nokia modem there's actually a SFP Cage inside with an SFP+ module in it connected to the fiber input.

I got in contact with my ISP asking if i purchased a gpon if i could use it and they got back to me with this response from chorus:

"It would not commission in the network due to the mismatch in config to what is provisioned and the network is expecting verse what the customer has done themselves. Ideally in these scenarios we would ask the customer to leave “chorus network untouched” as the ONT remains property of Chorus and then if it goes missing it is a lost asset." - Chorus

has anyone had any experience or success in doing this that aren't on a business plan?

So you just said it's not GPON but rather XGS-PON and now you want to use a GPON SFP module. How would that work??

Spark Max Fibre using Mikrotik CCR1009-8G-1S-1S+, CRS125-24G-1S, Unifi UAP, U6-Pro, UAP-AC-M-Pro, Apple TV 4K (2022), Apple TV 4K (2017), iPad Air 1st gen, iPad Air 4th gen, iPhone 13, SkyNZ3151 (the white box). If it doesn't move then it's data cabled.

What is wrong with the Nokia ONT provided by your HyperFiber connection?

Thanks for your condescending response.

I didn't mention XGS-PON anywhere, though from your comment clearly you understand what technology I'm referring too and could infer my ultimate objective.

I came for insight and shared what I had observed, I do apologize for not having or knowing the exact terminology.

It doesn't fit in my network cabinet nicely and is "just another thing" I need to have plugged in.

I did try and use it as a router for a bit but every night it would wipe my port forwards and address reservations, you also can't specify the IP subnet at all so i asked them to change it and went back to my vyos box.

Been discussed on here and the answer is simply no.

I've attempted to go down this route myself and even with me having contacts within Chorus the answer was no.

You're stuck with the Nokia ONT I'm afraid...

I believe they were looking into it but that's probably what they are still doing . Eventually it might happen

There is no ability to use 3rd party PON SFP modules with UFB. These have to be supplied by Chorus.

There is no way to have a Hyperfibre connection delivered to a XGS-PON SFP module - but this is possible with higher end GPON bitstream plans.

Understood. I think in the back of my mind bitstream plans and hyperfiber were the same thing.

baffles me when I read "no, you can't do that with an SFP module" when the fiber is literally supplied via a SFP module to the nokia unit. is it a, "no it can't be done because the communication to your ONT is all Nokia proprietary" or "no because we don't wanna share the config info with the peasants"

Or maybe they don't want to deal with faults that arise from people using their own equipment?

did you pull that out of your ONT ?

The strange thing is that Chorus haven't struck the right formula for this yet. That is to say charging or able [legally] to charge the right amount for equipment or support of, for this service. Would a one off fee of $200 or $500 for the equipment to be provisioned be unreasonable?

Do like the rest of us plebs do and plug back in the 'ISP' supplied router for support of a broken connection then reconnect actual equipment.

@BMarquis is the expert here..

At purely a technical level though, it would honestly depend on what chrous are physically delivering over that GPON service.

Given this is being done with other services, most recently hyped up in canada.. It's no surprise it's being tried here. I'd recommend taking caution with going outside of what chorus have deployed.

You also likely will break the tests RSP's run before logging faults, which could result in false positives etc.

At risk of being set on fire by the community. Yes.

Likely get more if you had removed the fibre itself, since then you're risking it getting dirty etc.

It's always fun to yank a SFP, see how quickly a fire starts ;)

Lots to unpick here! Thanks for the tag @Hio77.

So, @gazzaspins the elephant in the room... Please don't pull the ONTs apart. The Hyperfibre ONTs are expensive and I cant guarantee what the outcome will be in the future when/if you have a fault and we find the ONT has been opened. It is quite possible you will be charged for the ONT if it has been damaged.

Now, onto SFPs...

Most importantly - What you have pulled out there is a transceiver - that means it is just the optical driver. The transceiver, in itself, is not an ONT. it contains no software. you could plug that into an SFP+ slot on a router and nothing will happen, it will not work.
Transceivers are, relatively to ONTs and SFP ONTs, cheaper. That's expected, they do less.

We have a bitstream service (BS3A SFP) which does have a full ONT SFP as part of that product.

SFP ONTs are more expensive than a standard ONT. Personally, for standard GPON, I've seen them push the limits of SFP+ power capability. Heat dissipation can be an issue. I'd hate to think what that looks like for XGSPON

XGSPON SFP modules are being investigated. The technology is relatively new, pretty expensive and we're keeping an eye on it with our vendors. See above comments about SFP+, heat dissipation, etc which is all even harder with XGSPON.

Cheers,
Brent

As you can tell, actually, neither of those.

There is an element of the former, not necessarily proprietary, but we have to have a network that is supported by our vendors.
Note that the GPON standard is, inherently, not totally open. There are some pushes in the industry for GPON interworking, but that hasn't flown despite being worked on for many, many, many years.

I can't talk commercials here, but we have SLA's to meet, we have to have a network which is supported, can be managed by our technicians, our provisioning, management, alarm systems, etc, etc.
