Abstract:
1. A network device of an optical network terminal (ONT), which transmits an optical signal to an optical line terminal (OLT); the network device comprising: an optical communication interface, which transmits the optical signal according to a transmission power; an input interface, which is operated for inputting a distance between the ONT and the OLT; a memory, which stores a plurality of distances and a database corresponding to the distances; a processor, which electrically connects to the optical communication interface, the input interface and the memory, and accesses the database corresponding to the distance, and then determines the transmission power of the optical communication interface according to the database; and a temperature sensor, which detects a working temperature in surroundings; the each database further comprising a plurality of working temperature, and a plurality of parameters respectively corresponding to the working temperature; wherein the processor obtains the parameter in the database according to the working temperature, and then sets the transmission power of the optical communication interface based on the parameter.
