PURPOSE: An optical communication multiplex device for a vehicle and a method thereof are provided to comprise a data transmitting line among plural loads to be mounted in a car by using a multiplexing technique, thereby simplifying a complicated communication network to raise the reliability of a car communication system. CONSTITUTION: Plural loads(1,2,3,4,5,6) have transmission units(Tx) and receiving units(Rx) which are connected with one optical communication line respectively. A control unit(10) receives communication paths for data communication from the plural loads(1,2,3,4,5,6), and outputs a control signal for changing a length of a specific optical communication line to activate communication between a transmission unit and a receiving unit of a corresponding load. A distribution unit(22) connects plural optical communication lines in order to pass a phase signal identical with the optical communication line connected to the transmission unit. A union unit(24) unites optical communication extended from the distribution unit(22) in order not to be overlapped with the receiving unit. A multiplex unit(20) includes contact resistance to be mounted in the plural optical communication lines to generate heat according to a control signal of the control unit(10). |
