OPTICAL TRANSCEIVER, AND METHOD OF MANUFACTURING OPTICAL TRANSCEIVER

PROBLEM TO BE SOLVED: To maintain a predetermined impedance while suppressing crosstalk between transmission and reception in single fiber bidirectional transmission.SOLUTION: An optical transceiver 1 includes a single fiber bidirectional optical transceiver device 30, a circuit board 4, a transmission side FPC5, a reception side FPC6, and a separation wall 7. The single fiber bidirectional optical transceiver device 30 includes an LD stem 31 which converts electric signal to optical signal for transmitting, and a PD stem 32 which receives the optical signal and converts it to an electric signal. The transmission side FPC5 electrically connects the LD stem 31 to the circuit board 4. The reception side FPC6 electrically connects the PD stem 32 to the circuit board 4. The separation wall 7 is formed between the transmission side FPC5 and the reception side FPC6, and is grounded to a case 2 of the optical transceiver 1. The reception side FPC6 is provided by being bent such that a substrate surface is inside, between the case 2 and the separation wall 7, and a microstrip line is formed on the substrate surface.
