In nbn™'s Distribution Fibre Network (DFN) and Local Fibre Network (LFN), Uni-directional testing is performed using an Optical Time Domain Reflectometer (OTDR) to characterise the optical link at both 1310nm and 1625nm wavelengths. An OTDR sends thousands of pulses of light into a fibre at these wavelengths to create a Trace.

2022年9月10日 · apparently there is missing infrastructure (suspect the DJL) and they have only just realized it. So this isn't blocked pits, or difficulty installing – this is looking like someone just 'missed' the fact there is nothing to connect me to.

On completion, learners will have the confidence to build common network attributes including all optical joint enclosures used within the nbn™ optical architectures (TFN,DFN and LFN) as well as splicing ribbon and stranded optical cable types.

2023年2月21日 · can anyone detail (with photos) the route which nbn data typically travels once it leaves the home/pcd? It'd different depending on the platform. Do you have NBN via HFC, Wireless, FTTN. FTTB or FTTP?

NBN是澳洲独有的网络名称，全称是national broadband network，其实就相当于国内的光纤。 根据光纤接入的方式不同，大致分为 FTTP ， FTTB ， FTTC ， HFC 。 接下来给大家一一介绍。

与FTTN不同，FTTC的入户电话线不直接接入WiFi modem，而是先要接在一个由NBN提供的名为NBN Connection Device (NCD)的网络连接装置上，之后再接到WiFi modem上。 一般NCD背后有一个Gateway接口，它可以接WiFi modem。 HFC (Hybrid Fibre Coaxial) HFC：光纤电缆混合技术，光纤铺设到Cable/同轴电缆的分线节点，节点里的设备先将光信号转换成电信号，之后由电缆接入到户。 HFC速度上比FTTN和FTTB更快，已经铺设Cable的区域基本上都可以接入HFC。 …
