D-Link DPN-FX3060V GPON Router
A GPON WiFi Router (All in One) based on Realtek SoC Processor that given by TM for Unifi Ultra Subscriber,
it share same Realtek LUNA SDK as my PON Stick Project. So I quite familiar with the layout.

Specification
SoC: RTL9607DQ (Cortex A55), 4 Core @ 1GHz, AArch64, ARMv8
RAM: 512MB DDR3L @ 1866MT/s
MEM: 256MB SPI Flash Winbond
OS: Realtek ASDK64, Linux Kernel 5.10.70 (glibc v2.30)
MB: Realtek Taurus ENG Board

A1 (White)
WiFi6: RTL8852CE (2.4GHz & 5GHz)

B1 (Black)
WiFi6: RTL8192XBR (2.4GHz) + RTL8832CR (5GHz)
LAN1: RTL8221B Switch Chip (HiSGMII to 2500Base-T)

Discovery 10G
I found stock firmware has 10G PON (XGPON, XGSPON). Maybe TM have planning to migrating


Known Issue
1. Prior to B1 Hardware @ V2.0.2 have issue to set bridge mode on certain OLT, temporary fix is by accessing UART at change FwdOp to 0x02
2. Prior to B1 Hardware @ V2.0.2 when in bridge mode, LAN side management such as WebGUI, SSH, Telnet being killed by deep ME 171 (ex: Alcatel-Lucent/Nokia OLT)
3. Both Hardware has so called "Cloud IoT" for D-Link Air, it always running and always watching, other considered this as Backdoor

Backdoor
D-Link security track record is not that great, even both hardware shipped with Cloud IoT for D-Link Air by default! UART Log
If you concern about security of your network, you can use old ONU or PON Stick for 2Gbps

When use of PON Stick to avoid backdoor, can re-use this D-Link as ATA Device, I recommend get own ATA or Desktop SIP Phone

Management Entities Issue
OMCI ME can be very complex and total control of your ONT even without TR069! This mean TM can disallow Bridging and Force creation of PPPoE inside the Router!

Example of Simple OMCI Stack

* based on Alcatel-Lucent/Nokia OLT

ME Point
The RLT9607DQ has HiSGMII which can be paired with RLT8221B for 2.5GbE Access, but it use wrong ME Point, this can be fix by adjusting the OLT or Hack


Nijika Firmware A port form PON Stick Project


I have ported my PON Stick Project to both hardware, In my spare time, I manage to add OLT Info page and bug fix!

As you can see, even on same OLT, the way VLAN is being push, set and manage is different, for example my fiber VLAN400 (VoIP) doesn't exist on LAN1 UNI but only exist on VEIP UNI
This discrepancy among OLT's make many user unable to bridge!

HWTC	48575443
UBNT	55424e54
ZTEG	5a544547
-	0x00**

* FHTT send 0x00 to ONT as allowing other ONT work on FHTT OLT
** Sometime TM use off-brand OLT on Kampung/under-develop area

OLT Issue
On my experience during PON Stick deployment, there are many ME 171 to map. Rank from top (most troublesome)

1. Fiberhome (FHTT) (most troublesome)
2. Alcatel-Lucent/Nokia (ALCL)
3. Huawei (HWTC)
4. ZTE (ZTEG) (least troublesome)
If you ask me, FHTT is crap to work with! I hate FHTT Priority Queue so much!

Share OLT Status Page
Please update the firmware to correct Hardware A1 or B1, and share your OLT Info just like screenshot above,
This way we here can know which OLT are you on, either troublesome FHTT or awesome ZTEG

Firmware download can be found on next post
