That can transfer large amounts of data, such as UHD-quality video at a high speed, it discloses a wireless optical transceiver. Wireless optical transmission and reception device according to the present invention is formed such that the insertion fastening to be communicated to the terminals of the terminal, the power supply in the power supply via the terminals of the device can be supplied; Receiving service data through the terminal of the terminal, a conversion signal for converting a data signal format in the form of a single signal (TXDi), and send a single signal (TXDi) of the converter; Control section for storing the data of a single signal (TXDI) to form the signal converting part to transmit and convert them to form a differential output signal (TXO +, TXO-) output; An optical signal generator for emitting converts the output differential signal (TXO +, TXO-) to the control unit outputs the optical signal; Sort lens which can adjust the angle of the light signals emitted are converted from the optical signal generator; And it includes an alignment to align the respective positions transceiver, and with an optical transmitting and receiving apparatus comprising a component as described above as a pair of data transmission may also be received.
