At March 7th, I bought ODI DFP-34X-2C2 from AliExpress (XPON Model)
I going to replace Stock ONU with ODI DFP-34X-2C2.
ODI DFP-34X-2C2 much better than V2801F in many ways! I recommend you to buy this ONU SFP.
Compatible GPON ISP
In 2 years of research, most ISP in the world are compatible with correct and valid OMCI Info.
In my country, Malaysia, confirmed work:
Compatible SFP Host
- Mikrotik RB5009UG+S+IN
- Mikrotik CCR2004-1G-12S+2XS (2.5Gb Support)
- Mikrotik CRS305-1G-4S+IN (2.5Gb Support)
- TP-Link TL-XDR5480
- Ubiquiti EdgeRouter 12
ODI DFP-34X-2C2 support many LAN mode such as:
|2||1Gb SGMII PHY|
|3||1Gb SGMII MAC|
|4||2.5Gb HSGMII PHY|
|5||2.5Gb HSGMII MAC|
Make sure your router/switch SFP are compatible with these!
ODI DFP-34X-2C2 has auto SFP host negotiation, it may take time to establish a link
First of all, plug your new ODI DFP-34X-2C2 into SFP
This setup using default Mikrotik configuration, default Firewall, default LAN Address.
Remove SFP as bridge member
Go to Bridge ➡ Ports Tab ➡ #7
Add SFP as WAN Interface List
This will allow you to access ODI DFP-34X-2C2 WebGUI and Telnet from different subnet
Go to Interface ➡ Interface List ➡ ➕
List: WAN Interface: sfp-sfpplus1
Add SFP IP Address
Go to IP ➡ Address ➡ ➕
Address: 192.168.1.100/24 Network: Interface: sfp-sfpplus1
Now test ping to

Got response, now start configure
Setting ODI DFP-34X-2C2 quite easy when using telnet.
Assume your ODI DFP-34X-2C2 firmware at
Clone OMCI Info
High chance your OLT wont accept or not provision when using illegal ONU, ISP may use Universal ONU deployment, brand and model interchangeable, but ISP can limit which brand and model on their network.
This step are very important to make your ODI DFP-34X-2C2 work!
Login into stock ONU WebGUI, navigate to Device Information like this
This what you need
While you in Stock ONU, get PLOAM Password, usually at ⚙ ➡ ONT Authentication
Login ODI DFP-34X-2C2 via telnet with
admin as username and password.
flash set command in telnet to apply new settings!
Make sure replace example value with yours! *
More user TM-Unifi and TM-Maxis reported minimal setup manage to have Internet.
You only need:
- Hardware Version
- PLOAM Password (in HEX)
flash set OMCI_TM_OPT 0 flash set HW_HWVER 168D.A flash set GPON_PLOAM_FORMAT 1 flash set GPON_PLOAM_PASSWD 31323334353637383930 reboot
168D.A is Huawei HG8240H5, TM have support multiple ONU brand, only valid ONU can be use, using Hardware Version determine which ONU model is authorized
Login into WebGUI, see if you got
O5 ONU Status
If minimal setup failed, you need doing complete clone OMCI Information
Your PLOAM Password in HEX, replace
Use ASCII to HEX to convert your PLOAM ASCII Password to PLOAM HEX Password
flash set GPON_PLOAM_FORMAT 1 flash set GPON_PLOAM_PASSWD 31323334353637383930
For other RTL960x based system XPON SFP (V2801F, TWCGPON657, …) the
GPON_PLOAM_PASSWD only accept ASCII (10 char)
OMCI OLT Compatibility
This make your ODI DFP-34X-2C2 very compatible, it will reply
OK no matter what OMCI is
flash set OMCI_OLT_MODE 1 flash set OMCI_FAKE_OK 1
|0||Default ODI OMCI Value|
|1||Using Huawei MA5671a OMCI Value|
|2||Using ZTE ONT OMCI Value|
|3||Using predefined custom OMCI Value|
|21||Force own OMCI Value by triggering |
OMCI Device Properties
This make your ODI DFP-34X-2C2 like your stock ONU, making OLT authenticate your new ONU SFP!
flash set OMCI_SW_VER1 V5R019C00S125 flash set OMCI_SW_VER2 V5R019C00S125 flash set GPON_ONU_MODEL HG8240H5 flash set GPON_SN HWTC12345678 flash set PON_VENDOR_ID HWTC flash set HW_HWVER 168D.A flash set HW_CWMP_MANUFACTURER 'Huawei Technologies Co., Ltd' flash set HW_CWMP_PRODUCTCLASS HGU
Reboot ODI DFP-34X-2C2 to take effect, usually take 2 or 5 minute to start.
Now you can setup PPPoE internet as usual
Or move VLAN parent Ethernet to
Low Upload Speed
If your upload speed way less, enter
diag utility via telnet and do this:
bandwidth set ingress port all rate 4194296 bandwidth set egress port all rate 4194296
I have been research on this almost 2 years, all troubleshot, firmware, etc… can be found here:
