An FOT(Fiber Optical Transceiver) optical connecter structure for automatically sensing and recovering a ring brake of a MOST(Media Oriented Systems Transport) network is provided to secure a MOST network system with high reliability and to reduce wiring harness by eliminating LIN(Local Interconnect Network) bus-type RBD(Ring brake diagnosis). A MOST network system is composed of a MOST transceiver receiving digital data from a microcomputer and an AV(Audio/Video) signal processing IC(Integrated Circuit), converting the digital data into a MOST format, and outputting an electric signal, and transmitting a transmission channel(Tx) and an input received signal(Rx) to the microcomputer and the AV signal processing IC; a serial damping resistor matching impedance of the transceiver and an FOT optical connecter and coping with EMC(Electromagnetic Compatibility); and the FOT optical connecter comprising two parts converting the transmitted electric signal into an optical signal and the received optical signal into an electric signal. A transmission detecting circuit(1) is installed between the MOST transceiver and a transmission converting unit of an FOT optical connecter module. A reception on/off switch(2) and a buffer circuit(3) are installed between the MOST transceiver and a transmission converting unit of the FOT optical connecter module. The transmission detecting circuit is connected to the reception on/off switch of the buffer circuit. A transmission LED(Light Emitting Diode)(4) of the transmission converting unit of the FOT optical connecter module is connected to the buffer circuit.
