XGS1250-12 and SFP+ PM7000-01 XGS-PON transceiver?
Hello,
I am trying to figure out how I can skip my Zyxel AX7501-B0 gateway.
When inserting the Zyxel PM7000-01 SFP+ transceiver into the XGS1250-12 switch, I get no link and the port status stays down. Inserting the transceiver back into the AX7501-B0, I get link again.
Please advice on how to get any kind of debug information from the switch in regards to why it is not able to use the SFP+ transceiver? I expected it to be compatible since all are Zyxel parts, but I don't see it listed in the datasheet but I wouldn't expect XGS-PON transceivers to be listed neither..

Hi @HS1542,Apology for the late reply. I took some time to build the test surrounding.My test result is that the PM7010-R0 can work with XGS1250-12, and the packets can be forwarded.So, you might need to contact your ISP for changing the Serial number of the SFP module.If there have any questions, please feel free to ask.Melen0

Dear @HS1542 ,
The XGS1250-12 is not designed for the G-PON use, so it does not support the G-PON's transceiver.
You can click the link below to have the support list for XGS1250-12:

Hello Ivan,
Thank you for your reply.
I am not familiar with PONs, but do I understand correctly that for instance the PM7010-R0 transceiver could be used as an alternative to connect a layer2 switch and open up for removal of the AX7501-B0 ?

And I don't think that your ISP will allow anyone to connect to their infrastructure without an authorized CPE.

Hi @HS1542,The Zyxel AX7501-B0 gateway cannot be skipped since PON-ONT has a registration process with ISP to enable the link, which the XGS1250 does not support.We recommend you connect the XGS1250 under the AX7501-B0 gateway.

That is fine, but what about the PM7010-R0 transceiver? If I understand correctly, this alone should be able to perform registration, given that the ISP will acknowledge the handshake?0

For me it seems like the PM7010-R0 will act as the gateway and complete the negotiation.
Just look here: https://service-provider.zyxel.com/na/en/products/fiber-oltsonts/xgs-pon/sfus/pm7010-r0 - Under application diagram you will se an applicable configuration with the transceiver connected to a switch.0
