GPON - Modem-ID

Hey guys,

I finally got my fiber optic internet connection.
Now I would like to continue using my RB3011 as a router and "modem".

I bought a GPON transciever from AVM and installed it in the SFP port.
My provider now requires a so-called "modem ID".

In the case of a Fritzbox, this can be found on the router's type plate and consists of 12 characters.

How do I find out the modem ID of the RB3011?
It is not the serial number of the GPON SFP.

Thanks.

eg. GPON_SN ABCD12345678
You must take serial number from provider (Fritzbox) or make it by yourself. I have Huawei ONT and to have SN must take first half of the number and convert it trough HEX -> ASCII, eg. Huawei: 48575443 -> HWTC and the second half you must use instead of 12345678

I bought a GPON transciever from AVM and installed it in the SFP port.
You need an SFP with integrated ONU, not just an SFP transceiver.

...must take first half of the number and convert it trough HEX -> ASCII
by my mikrotik SN i get x= as ASCII :)
So i think, i have to use HWTC and then the SN of the SFP.

But i think i found a Solution (but i have not tested yet) here:

I have bought a SFP with ONU and MAC, thanks to @nFin1ty fr this information!
