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.

In this guide, I using TM–Maxis fiber and Mikrotik RB5009UG+S+IN.

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:

1. TM-Unifi
2. TM-Maxis
3. TIME
4. Allo

Compatible SFP Host

1. Mikrotik RB5009UG+S+IN
2. Mikrotik CCR2004-1G-12S+2XS (2.5Gb Support)
3. Mikrotik CRS305-1G-4S+IN (2.5Gb Support)
4. TP-Link TL-XDR5480
5. Ubiquiti EdgeRouter 12

ODI DFP-34X-2C2 support many LAN mode such as:

LAN_SDS_MODE	Type
0	1000base-T
1	1000base-X
2	1Gb SGMII PHY
3	1Gb SGMII MAC
4	2.5Gb HSGMII PHY
5	2.5Gb HSGMII MAC
6	2500base-X

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

Setup

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

Change Interface to ether1

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

Test

Now test ping to 192.168.1.1 from 192.168.88.1 network.

Got response, now start configure

Settings

Setting ODI DFP-34X-2C2 quite easy when using telnet.

Assume your ODI DFP-34X-2C2 firmware at V1.0-220304

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

PLOAM Password

While you in Stock ONU, get PLOAM Password, usually at ⚙ ➡ ONT Authentication

Setup ODI

Login ODI DFP-34X-2C2 via telnet with admin as username and password.

Enter flash set command in telnet to apply new settings!

Make sure replace example value with yours! *

Minimal Setup

More user TM-Unifi and TM-Maxis reported minimal setup manage to have Internet.

You only need:

• Hardware Version
• PLOAM Password (in HEX)

Like this:

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

Hardware Version 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

Full Setup

If minimal setup failed, you need doing complete clone OMCI Information

PLOAM Password

Your PLOAM Password in HEX, replace 31323334353637383930

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

OMCI_OLT_MODE value	Description
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 segmention fault duing rc

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

Reboot ODI DFP-34X-2C2 to take effect, usually take 2 or 5 minute to start.

reboot

Internet!

Now you can setup PPPoE internet as usual

Or move VLAN parent Ethernet to sfp-sfpplus1

That’s it!

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
