The ONT (Optical Network Terminal) box in electrical and architectural design is typically located in a utility room, communications closet, or near the main electrical panel of a building. It is positioned where the fiber-optic cable enters the structure, ensuring a central and accessible point for internet distribution.
In residential buildings, the ONT is often placed in the garage, basement, or a low-traffic area to avoid interference while maintaining easy access for maintenance.
In commercial settings, it is installed in a dedicated IT or telecom room to integrate with the structured cabling system. Proper ventilation, power supply proximity, and adherence to service provider guidelines are key considerations in its placement.
