# Hacking [RTL960x](https://www.google.com/search?q=rtl9601ci+datasheet)
* 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
* Correction: `CI` not `C1`

# RTL960x Family
| Stick | SoC | NAND |

# Where to buy?
I recommend [ODI DFP-34X-2C2](https://www.aliexpress.com/item/1005003515662920.html) because
* Much cheaper than **VSOL V2801F** & **CarlitoxxPro CPGOS03-0490 v2.0**!
* Using latest SoC **RTL9601D**!
* Support **HEX** PLOAM Password! *<sup>Using [`220304`](https://github.com/Anime4000/RTL9601C1/blob/main/Firmware/DFP-34X-2C2/M114_sfp_ODI_220304.tar) Firmware</sup>*
* Support [2.5GbE](https://github.com/Anime4000/RTL960x/issues/17#issuecomment-1100272965) via **HiSGMII** or **2500Base-X**! *<sup>See [Compatibility](Docs/2.5Gb.md#device-list), [SpeedTest](https://github.com/Anime4000/RTL960x/issues/17#issuecomment-1100272965)</sup>*
* Using newer SFP Body with intergrated heatsink *<sup>See [Picture](https://github.com/Anime4000/RTL9601C1/issues/17#issuecomment-1077681925)</sup>*
* Very efficient, just **45°C** without fan!
* Automatic/Transparent bridge like VSOL V2801F! *<sup>Using [`220304`](https://github.com/Anime4000/RTL9601C1/blob/main/Firmware/DFP-34X-2C2/M114_sfp_ODI_220304.tar) Firmware</sup>*
* Support 4-port ONU Emulation

# VSOL V2801F Alternative
I recommend [TWCGPON657](https://item.taobao.com/item.htm?spm=a1z09.2.0.0.c0552e8d7UBYLF&id=597031866488) with [V2801F Firmware](Firmware/TWCGPON657/README.md) as V2801F substitute
* Limited 2.5GbE Support *<sup>wrong `LAN_SDS_MODE` can lock you out, no auto switch</sup>*
* **HEX** PLOAM Password require modification from [@zry98](https://github.com/zry98/SFP-GPON-ONU#modules-using-rtl8672--rtl9601c-chipset)
* Automatic/Full Transparent
* Support 4-port ONU Emulation

# 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

## Multiple Service
![HG8240H5](Docs/Images/Ports%20Provisioning%20Multi%20Port%20Service.png)

Based on [ru-board](http://forum.ru-board.com/topic.cgi?forum=8&topic=80480&start=1360#2) **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
