Abstract: An optical transceiver includes a single-fiber bidirectional optical transmission/reception device, a circuit board, a transmission-side FPC, a reception-side FPC and a separation wall. The optical transceiver includes a single-fiber bidirectional optical transmission/reception device includes an LD stem that converts an electric signal into an optical signal and transmits it, and a PD stem that receives the optical signal and converts it into an electric signal. The transmission-side FPC electrically connects the LD stem and the circuit board. The reception-side FPC electrically connects the PD stem and the circuit board. The separation wall is formed between the transmission-side FPC and the reception-side FPC, and grounded to the chassis of the optical transceiver. The reception-side FPC is folded and set between the chassis and the separation wall such that the board front surface is an inner side, where the micro-strip line is formed on the above board front surface.
