Smart remote node optical network unit and operation method thereof

A smart remote node optical network node comprising:

• an optical layer monitoring unit configured to transmit a monitoring light signal to an optical network unit through an optical switch and receive a monitoring light signal reflected from the optical network unit through the optical switch;
• an infra recognition unit configured to recognize whether an optical connector is connected to an output port of a remote node and an identification number of the optical connector when the optical connector is connected thereto;
• and
• a control unit connected to the optical layer monitoring unit and the infra recognition unit and configured to control the optical switch according to a recognition output from the infra recognition unit and to control recognition and monitoring operations of the remote node according to a remote node application,
• wherein the monitoring light signal reflected from the optical network unit is provided to an optical line terminal, which communicates with an optical distribution network integrated management server through an optical splitter.
