Abstract: An optical transmission and reception connector system includes a cable that has a plug section formed at both ends thereof so as to relay and transmit light and an interfacing module that is mounted on an electronic apparatus and that includes an insertion space into which the plug section is detachably inserted. The cable is provided with a first relay optical path and a second relay optical path. The interfacing module includes a receptacle unit in which a first internal optical terminal and a second internal optical terminal for transmitting and receiving light to and from the cable are separated from each other, an optical transmitter unit, an optical receiver unit, and a main optical transmission unit that includes a first main optical path formed between the optical transmitter unit and the first internal optical terminal so as to transmit light output from the optical transmitter unit through the first internal optical terminal and a second main optical path formed between the second internal optical terminal and the optical receiver unit so as to be separated from the first main optical path and to transmit light received from the second internal optical terminal to the optical receiver unit. The plug section of the cable is formed such that an upper part and a lower part are symmetric with respect to the center thereof without depending on the insertion direction thereof, and the cable or the receptacle unit is formed to divide or switch an optical path so as to enable transmission of light by the optical transmitter unit and reception of light by the optical receiver unit.
