OPTICAL NETWORK TERMINAL AND METHOD FOR DETECTING TRANSMISSION ERROR IN OPTICAL NETWORK TERMINAL

摘要

Provided are an optical network terminal (ONT) and a method for the ONT to detect an optical transmission error. The ONT is connected with an optical line termination (OLT) and constituting a passive optical network (PON), and includes an optical transmitter configured to transmit an optical signal to the OLT, an error detector configured to detect an error of the optical transmitter; and a controller configured to transmit an error message to the OLT through the optical transmitter when the error detector detects an error of the optical transmitter.
