<p>[Problem] To provide an optical transceiver and others that allow for easy performance of timing adjustment between SDA and SCL signals without loss of removability. [Solution] An optical transceiver (10) comprises: an I2C slave circuit (11) that is connected to an I2C master circuit (21) via an SCL line (31) and an SDA line (32) when the optical transceiver (10) is mounted on an optical communication apparatus (20); a variable delay circuit (12) that is inserted between the I2C master circuit and the I2C slave circuit and that causes a delay in signals transmitted via at least one of the SCL and SDA lines; a control signal generating circuit (13) that generates a control signal to set a delay amount of the delay caused by the variable delay circuit; and a nonvolatile storage circuit (14) that has already stored numerical values of the control signal. The control signal generating circuit outputs the control signal on the basis of a numerical value read from the storage circuit.</p> |
