Hacking RTL960x

• Hacking V2801F, TWCGPON657 & DFP-34X-2C2 to suite your ISP Fiber
• GPON market is a mess, plus explicit OMCI cause ONU Stick did not work
• 4-port ONU Emulation Table

RTL960x Family

Stick	SoC	NAND	Mode	4-port EthUni
V2801F	RTL9601CI	8MiB (64Mb)	SFU	YES
TWCGPON657	RTL9601CI	16MiB (128Mb)	SFU	NO
UFiber Instant	RTL9601CI	8MiB (64Mb)	SFU	NO
DFP-34X-2C2	RTL9601D	8MiB (64Mb)	Both	YES*

SFU vs IGD

Code	Full name	Meaning
SFU	Switch Fabric Unit	Simple device that just bridge from PON to LAN's, it may have VoIP
IGD	Internet Gateway Device	ONU with routing capability, has wifi, tldr; Router

Where to buy?

ODI DFP-34X-2C2 ^Recommended!

1. HSGQ @ Taobao Mall
2. Fibershow @ AliExpress (Choose XPON)

Feature

• Much cheaper than VSOL V2801F & CarlitoxxPro CPGOS03-0490 v2.0!
• Using latest SoC RTL9601D!
• Support HEX PLOAM Password! ^{Using 220304 Firmware}
• Support 2.5GbE via HiSGMII or 2500Base-X! ^{See Compatibility, SpeedTest}
• Using newer SFP Body with intergrated heatsink ^{See Picture}
• Very efficient, just 45°C without fan!
• Automatic/Transparent bridge like VSOL V2801F! ^{Using 220304 Firmware}
• Support 4-port ONU Emulation

V2801F Alternative

1. TWCGPON657 with V2801F Firmware as V2801F substitute
2. Opton GP801R ^{Found by @AreYouLoco}

Feature

• Limited 2.5GbE Support ^{wrong LAN_SDS_MODE can lock you out, no auto switch}
• HEX PLOAM Password require modification from @zry98
• Automatic/Full Transparent
• Support 4-port ONU Emulation
• Modern WebGUI

Triple Play Multiple ISP Problem, 4-port ONU Emulation

• Majority fiber vendor support multiple ISP
• ISP provide Triple Play service (Internet, VoIP & IPTV)
• Vendor supply 4-port ONU for each service or ISP

4-port ONU Emulation

Based on ru-board, xPON Stick with 4-Port Emulation support is limited!

ONU LAN Port Binding example

If you using 4-port ONU like Huawei HG8240H5, Nokia G-240G-E and Router connected to ONU LAN 2/3/4, you have limited option, I recommend ODI DFP-34X-2C2 with 220304 or newer firmware.

Table 4-port ONU Emulation

Here list of xPON Stick on the market that support 4-port ONU Emulation:

xPON Stick	Huawei HG8240H LAN Port						Firmware
	Root	1️⃣	2️⃣	3️⃣	4️⃣	PVID
Huawei MA5671a	✔️	❌	❌	❌	❌	✔️	OpenWRT
Nokia G-010S-P	✔️	❌	❌	❌	❌	✔️	OpenWRT
ODI DFP-34X-2C2	✔️	✔️	❌	❌	❌	❌	210702, 220527
ODI DFP-34X-2C2	✔️	✔️	✔️	✔️	✔️	❓	220304, 220414
TWCGPON657	✔️	✔️	✔️	✔️	✔️	❌	C00R657V2801F_V1.9.0-220404.tar
V-SOL V2801F	✔️	✔️	✔️	✔️	✔️	❌	Stock Firmware

✔️ Port Emulation Support

❌ Not Supported

Root mean your ONU is All in One where PPPoE/DHCP ended inside ONU (not bridge/route mode)

PVID is VLAN untagging, at router side, WAN connected without VLAN, useful consumer router such as TL-XDR5480 without VLAN support
