### Feature
* 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 via [**HiSGMII** or **2500Base-X**](Docs/FLASH_GETSET_INFO.md#lan_sds_mode-min-1-max-6)! *<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

# 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
* [Modern WebGUI](WebGui#example)

# 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](http://forum.ru-board.com/topic.cgi?forum=8&topic=80480&start=1360#2), xPON Stick with **4-Port Emulation** support is limited!

### ONU LAN Port Binding example
If you using 4-port ONU like [Huawei HG8240H5](https://www.google.com/search?q=HG8240H5), [Nokia G-240G-E](https://www.google.com/search?q=G-240G-E) and Router connected to ONU LAN 2/3/4, you have limited option, I recommend [ODI DFP-34X-2C2](https://www.aliexpress.com/item/1005003515662920.html) with `220304` or newer firmware.

> `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
