ONT lights and their meanings
An Optical Network Termination (ONT), also known as Client Premises Equipment (CPE) is the Fibre connection box installed inside your house. The ONT device connects your fibre router to the fibre network. We will look at the different ONT devices that our Fibre Network Operators (FNOs) use, how they work and what the signal lights on each device means.
Here are a few ONT devices we will cover:
We have grouped the ONTs based on their brand names and the FNOs that use them. There may be multiple FNOs using the same or similar ONT brand and model.

| 2. CTC & Raycore | Vuma Trench or Vuma Core. | ||
| 3. CTS | TT Connect. | ||
| 4. DASAN | Octotel. | ||
| 5. Huawei | Vuma Reach, Vuma Aerial, Mitsol, Evotel, & Openserve. | ||
