Optical Network Unit (ONU)

An Optical Network Unit (ONU) is a device that connects your home or business to a fiber optic internet service. It receives high-speed light signals from a fiber optic cable and converts them into electrical signals your devices can use, like Wi-Fi, Ethernet, or phone lines. Essentially, the ONU acts as a translator and distribution point, enabling fast, reliable internet access from the main fiber network to all your connected devices. It’s a key component in fiber optic networks, providing the interface between the outside high-capacity fiber lines and your internal network.
