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

Guide, Links, Info

  1. Setup SFP XPON ONU Stick
  2. Flash Get, Flash Set
  3. Diagnostic Commands
  4. Hidden Link, Firmware Update
  5. TWCGPON657 with V2801F firmware
  6. V2801F Auto Reboot
  7. Firmware Emulator

With my issue:

  • V2801F
    • Support n-Port ONU Emulation
    • Support OMCI explicit provision override OMCI_FAKE_OK 1
    • Good Firmware, support many ISP (Global)
    • Build not strudy
  • TWCGPON657
    • Not Support n-Port ONU Emulation
    • Not Support OMCI explicit provision override
    • Bad Firmware, limited ISP
    • Silm & Tight build

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

Multiple ISP

HG8240H5

Multiple Service

HG8240H5

Based on ru-board 4-Port Emulation is limited, not many xPON Stick can understand, only V2801F do support it, because my Internet comes at Huawei HG8240H LAN Port 2 (LAN 1 for Main ISP, LAN 2 for 3rd party ISP)

In this table, list of xPON Stick that support 4-port ONU Emulation

Huawei HG8240H LAN Port
xPON Stick Root 1 2 3 4
DFP-34G-2C2 (ZTE) ✔️ ✔️
DFP-34X-2C2 (ZTE) ✔️ ✔️
DFP-34X-2C2 (Realtek) ✔️
TWCGPON657 ✔️ ✔️
V2801F ✔️ ✔️ ✔️ ✔️ ✔️

✔️ Port Emulation Support | Not Supported

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

I strongly recommend to get V2801F or CarlitoxxPro (Realtek), these xPON Stick support 4-port Emulation!

Firmware might interchangable each other, flash it at your own RISK!
