OLT / ONT Units

GAO’s OLT (Optical Line Terminal) / ONT (Optical Network Terminal) units are networking devices used in the deployment of fiber optic networks, specifically in the context of Passive Optical Networks (PON). Our OLT units are the central devices in a fiber optic network located at the service provider’s central office or data center. It manages the distribution of data and services to subscribers, converts electrical signals into optical signals for transmission over fiber optic cables, and performs various network management functions. Our ONT units are the devices installed at the subscriber’s premises in a fiber optic network. It receives optical signals from the OLT and converts them back into electrical signals that can be used by the subscriber’s devices.  

GAO’s OLT / ONT units are composed of a central processing unit (CPU), optical line interface, uplink interfaces, downlink interfaces, management interfaces, electrical interfaces, and power supply. 

The other common names of OLT/ONT units are optical line terminations, optical line gateways, optical access nodes, central office terminals, fiber aggregation nodes, optical network units, fiber access terminals, optical hubs, optical network units, network termination units, optical network gateways, customer premises equipment (CPE), optical network terminations, optical termination devices, customer optical units, and fiber termination units.
