Abstract:
(EN) Disclosed are a method for detecting a disconnection and a disconnection location in an optical communication network system having a ring network structure, and an optical communication network system using the same. According to an embodiment of the present invention, provided is a method for detecting a disconnection location in a wavelength division multiplexing (WDM) optical communication network system, in which a central office terminal and a plurality of remote terminals are connected in an optical ring network structure, comprising the steps of: allowing the central office terminal to generate a disconnection monitoring signal having a predetermined disconnection monitoring frame; converting the disconnection monitoring signal into an optical signal through a digital optical element of the central office terminal; allowing the central office terminal to bidirectionally transmit the disconnection monitoring signal, which has been converted into the optical signal, through an optical line of the optical ring network; and allowing the central office terminal to calculate a disconnection location by analyzing a frame of the optical signal bidirectionally received through the optical line of the optical ring network.
