The difference between an ONT and an OTO lies in their function and position in the fiber optic network:
ONT (Optical Network Terminal)
- Function: the ONT is a device that converts optical signals from the fiber optic line into electrical signals for use by your WLAN-Router and other network devices.
- Position: it is located inside your apartment or house and is connected directly to the fiber optic socket (OTO).
- Power supply: the ONT requires its own power source, as it actively processes and converts the signals.
OTO (Optical Termination Outlet)
- Function: the OTO is a passive fiber optic wall outlet that serves as the physical termination point of the fiber line in your home.
- Position: it is mounted on the wall in your home and acts as the interface between the fiber optic network and the ONT.
- Identification: the OTO has a unique identifier (the OTO ID) used to identify your fiber connection.
In short:
- The OTO is the outlet where the fiber line ends.
- The ONT is the powered device that connects to the OTO and makes the fiber signals usable for your home network.
