Does anyone have any pics of the internals of a Chorus ONT?

I'd like to understand what the fibre terminates to.

I'm hoping that someone has some pics from an install and shows what the techie does with the fibre within the ONT.

thanks in advance.

Hi, the Chorus Tech's do not open the ONT, on the rear of the ONT is a SC/AP fibre connector, they simply terminate the fibre from the street in the fibre containment that holds the ONT with a mating SC/AP connector and using a short SC/AP patch lead connect the two together.

I'm curious to know exactly what you are after and why - maybe I can help.

Note that physically opening the ONT case voids the warranty and, I believe, you are liable for damage and could be liable for future failures of the device

similar to...?

Not even close - that is an OLT end transceiver.

I *think* - as you haven't said why you are after the info - I should probably refer you to this thread:

Hi, Brent will be able to clarify more, but unless the SFP is certified to operate on Nokia/ALU's ISAM its not going to fly. Regardless you can order an SFP format GPON terminal via your RSP that is supplied by Chorus and compatible with their ISAM.

Thanks Brent, just to clarify that I'm not going down a rabbit hole - I'm not after reverse engineering the Chorus equipment. I can't go into detail, sorry NDA/Confidential.

As a 'just asking in principle' what the optic spec is to cost a similar product that could one day be submitted for approval.

We don't have any kind of "ONT approval" for 3rd party ONTs at all - it's not something we do. Even new Nokia ONT introductions are not necessarily straight forward WRT integration with our products/services and systems.

I guess you might want to pm or email me if you want to carry on the discussion if it is sensitive.

Cheers,

Brent

Thanks Brent, I'm in Auckland (Grafton, under the Chorus Lab 🤣 )
It's early days, so not ready to pick up a conversation as yet. Would be useful at a later date I expect.

If you're thinking of connecting your own ONT to the Chorus network and running your fibre connection over that, I would say your chances would be slim to nil.

When I worked at TCL, people weren't allowed to connect their own personally-supplied cable TV boxes/cable modems to their network either (although some did try).

Something that hasnt yet been said is the technical reason why it wont work:

The OLT at the exchange configures the end ONT device -and- transmits the VLAN packets to a specific serial number.

Unless your ONT and its serial number is a chorus owned device, it wont be getting approved or recognized by the OLT at the exchange.

Once the ONT serial number is known to the chorus provisioning system, then it needs to be the same brand as the OLT for compatibility.

Thanks for the pics. Curious that Nokia have what looks like a custom transceiver, but there is a pinout for what looks like a SFP module. I guess either will work, and it's a cost reduction method.

Thanks again.
