No. From box perspectiver it looks the same, but it is not the same.
Ethernet PHY that is inside 9601D chipset can not go above 1Gbit. There is another interface/port in 9601D that can do 2.5G, but it is not pure ethernet, it is HiSGMII - normally used to connect to SFP port or to another chipset (chipset-to-chipset ethernet link).

And we use this port to connect to additionall ethernet PHY (rtl8221b) - and this extra chipset is connected to LAN port.
In this configuration it can do 2.5G on CAT5e cable.

There is no way to "tune" internal ethernet PHY to run faster, as 2.5G is rather a slower 10G/5G than a faster 1G, so requires some extra DSP operations.

Understood how you trick the chipset to grab more speed !
Ideally a SFP+ interface will be more convenient to satisfy most of the use case where each could choose the adapter to fit (fiber, coper), the question is could be standard speed like 1G/10G ? Because it's not common to have routing/security devices with 2.5Gbps supported speed.

In the same time if you control both hardware and software, is there any chance to have the following feature :
- set the vlan id to 832 (used by Orange in France) on the lan interface, it will be more easy to connect to standard device (router, firewall, etc...)
- set Cos to 6 (Vlan priority to 6) only for DHCP Request IPv4 and DHCP-PD Solicit IPv6 to match Orange France requirements, it will be more easy to connect to standard device (router, firewall, etc...)

If you can do that with a correct price, I think a lot of people in France would purchase your ONT Box because we would easily replace the Orange Box (DSL or Fiber) and put a standard device (router, firewall, Wifi Access Point, etc...).

I forgot some options to add to be fully compliant with Orange in France :
- vlan 832
- Cos 6 for DHCP request and renew (IPv4 and IPv6)
- DHCP Options to sert (IPv4 : 60,61,77,90 with value and IPv6 : 11,15,16,17)

In general all VLAN/Pbits operations are controlled by OLT. So if Orange uses VLAN 832, you would like to do what ? Pass it as tagged to LAN port ?
Overwriting vlan operations is possible, but it is a violation of OMCI protocol.

Is it possible in your case (as Orange customer) to officially connect your own ONT to their optical network, or you do it on your own risk ?
There are several aspects of such swap:
- if you change RGU to signle port ONT, the device might not work, as Orange will provision so called VEIP port but signle port ONT has so called EthernetUni.
So it is necessary, to switch to VEIP mode (pretent you are FunBox from config perspective)
- you need to clone GPON_SN and some others maybe (like PLOAM password) from original device.
- I'am not sure how about hardware version and model
- and I'am not sure if orange will not try to overwrite your firmware (automatic update)

Do you have working cases with SFP modules ?

No Orange does not allow to replace their Box provided by default.
It's our own initiative with no support.

There is a lot of people who replaced they default Box with their own hardware.
To give you a quick summary :

1) ONT
You have an external ONT (Huawaei) or recent Box with ONT built-in into the Box where you connect directly the Fiber into the box without any SFP ONT !
The following SFP ONT are working well if you clone your default ONT :
- Huawei MA5671A
- Nokia G-010S-A
- Alcatel G-010S-P
Carlitox Firmware are used to have an easier setup and configuration to clone the orignal ONT.

2) Device replacing the Orange Box

You should use the expected settings :
- vlan 832
- Cos 6 for DHCP request and renew (IPv4 and IPv6)
- DHCP Options to sert (IPv4 : 60,61,77,90 with value and IPv6 : 11,15,16,17)

There is different hardware used for this and some users are using a virtual machine with a dual SFP+ BMC57810 to link the HSGMII speed on the SFP ONT to a 10Gbps speed device like a Mikrotik CCR2004-1G-12S+2XS because you need power or hardware assistance to set the Cos 6 for DHCP request only !!!

Maybe we could talk over the phone if you need more details....?

Ok, drop an email to marcin.kuczera@leolabs.pl, I will send you my phone.

Hi Marcin, I have a few questions that will probably interest some of us here:

-> does it come with a GUI?
-> does it come with a root ssh shell?
-> what parameters will it be possible to modify via GUI / SSH (SN/SLID/ManufacturerID/HardwareVersion/SoftwareVersion/...?) I understand that you will set all this up for the client but it still can be useful if one changes Internet Access Provider.

Yes, it has a GUI, but it is better to do modifications via shell.
In this model, linux shell (root) is normally available, as it works as L2 converter so there is no access to device in normal usage conditions.

SN/SLID/ManufacturerID/HardwareVersion - possible to be changed with CLI commands, about software Version - you can also overwrite/enforce presentation of required software version - to be presented towards Orange as I suppose.

But sofware version after each upgrade is updated, so if you upgrade firmware, you need to update also software version parameter..

So your goal, is to pretend to be same view/look as original ONT provided by Orange ?

Exactly, my goal is to spoof as best as possible the ONT from the ISP. As it was said before, Orange probably enforces a whitelist of equipements on their OLT side.

Doable.
The basic check/authorization is GPON serial number. Sometimes also PLOAM /SLID.
But this is just to authorize. If OLT will try to enforce software upgrade (automatic) and it fails, ONT might stuck in non-working state (this depends on OLT vendor), or might reboot periodically.
About hardware description (model, version, CLEI code etc) - it is used to recognize device model in case of new provisioning and software upgrade.
