Tenda G103 ONU works on HUAWEI OLT


Today a friend from India an FTTH subscriber of RailWire ISP share the thoughts of his Tenda G103  ONU (Optical Network Unit) as a replacement to Huawei ONT (Optical Network Terminal).


Looking for serial port pin header very easy to guess just like the other wireless router that has Ground TX RX and VCC.


The good news firmware is base on opensource OpenWrt image_name=openwrt-lantiq-falcon-EASY98020

The Tenda ONU G103 is equip with 400MHz Falcon-D Lantiq Chips, with 64MB DDRAM and 8MB Flash.


Another interesting command line interface

To be continue will see the command line interface of this Tenda G103, this is absolutely applicable on PLDTHOMEFIBR, we can now replace our HUAWEI ONU/ONT with this device.
