The original model is the Ainopol ZH-VOLT, which is a compact GPON OLT SFP.

There are some clones, such as the Pacetech PAC-VOLT, which is a clone commonly sold on AliExpress.

@merbanan you could send photo from sfp module's label?

@merbanan i not found almost information about this module, but it seems to only work with certain devices, and this is a clone of a version only for the Chinese market. From what I found, few people had success with this module only with only chines devices. The bad thing is that they didn't say if it was used with a media converter or a switch with a MAC controller

Yeah, I have another ONT sfp stick that I need to test if it works with this module. My main goal with the device is to find something I can talk ploam with.

This olt stick only has one manufacturer so it should be possible to hack it as long as it is possible to get one device working.

My OLT arrived at the airport here in Brazil today, it will probably arrive by the end of the week or on the 17th

My Olt arrived, I already tested it and managed to get it working on the local network, but without internet access. It must be some kind of sharing problem. I'll take a look at the SFP physically, and as for the Linux software, it's not feasible. We'll have to reverse engineer the program to port it to Linux. With the TP-Link stock software, we can get a connection of 800~959 Mbps.

As for the OMCI, we don't have a log for it, so we'll just stick with the router part to test the PLOAM. @kvn193 and I can test it, but it would be useless because it's the same Xpon

internal photos, it seems to have an FPGA, but I haven't checked to see if it has a UART yet

Fudan Micro FMK50T2ef64.

The 2 testpoints to the right seems like GND and VCC. And the 3 test points to the left looks like IO.

sys wan2lan on 15

This command should mirror the wan onto the lan ports.

This should report some gpon link information.
