The provided document is a troubleshooting guide for an Optical Network Terminal (ONT), also known as a fibre box, which is a crucial component for connecting homes and businesses to a fibre broadband network. The guide is published by Tuatahi First Fibre, a New Zealand-based fibre network provider.
An ONT serves as the interface between the fibre optic network and your home or business network. Its primary function is to translate light signals from the fibre optic line, which comes from the External Termination Point (ETP) on your property, into electrical signals that your modem or router can understand. This enables your devices to access fibre broadband internet services. The ONT, along with the ETP and associated power cables, is owned by Tuatahi First Fibre and should remain at the property if you move.
The guide covers four main types of ONT models: HG8240, HG8240H, HG8240H5, and HN8250Ts (Hyperfibre). While the specific models vary in appearance and some features, their core function remains the same: to facilitate the conversion of optical signals to electrical signals for internet and, in some cases, telephone services.
The ONT typically features several indicator lights (LEDs) that provide visual feedback on its operational status. These include:
For Hyperfibre plans (2GB or more), the HN8250Ts model includes a dedicated 10G LAN port, which requires a CAT6A or higher standard network cable for optimal performance over distances up to 100m.
The ONT typically has an On/Off switch to power the device and multiple ports for connectivity:
The guide emphasizes several key maintenance and troubleshooting steps:
The guide also includes visual diagrams of the various ONT models and their ports, along with detailed explanations of what each indicator light signifies in different states (off, steady, blinking) for effective self-troubleshooting.
