Abstract
An optical line terminal includes an optical network interface having an optical receiver unit to convert an optical signal received from an optical network unit into an electrical signal and output a direct current bias monitoring signal and an error code detector to detect an error code in the electrical signal to output an error code indication signal, a storage to store therein a direct current bias table indicating a direct current bias corresponding to a direct current bias control parameter of the optical network units and a dynamic band allocation information table indicating communication time slot information allotted to each optical network unit and a control unit to receive the direct current bias monitoring signal and the error code indication signal and supply the direct current bias control signal to the optical receiver unit to thereby form one feedback circuit together with the optical network interface.
