Abstract
An optical transceiver of the present disclosure includes: a first light emitting element configured to perform electric-optic conversion at a first transmission rate; a second light emitting element configured to perform electric-optic conversion at a second transmission rate higher than the first transmission rate; a light receiving element configured to perform optic-electric conversion at a predetermined transmission rate; an optical sub-assembly accommodating the light emitting elements and the light receiving element; a circuit board having a plurality of integrated circuits which are configured to drive the light emitting elements and the light receiving element; a housing accommodating the optical sub-assembly and the circuit board, the housing having a longest dimension in a longitudinal direction thereof and having thermal conductivity; a temperature sensor configured to detect a temperature inside the housing; a temperature control unit configured to determine a control value to be designated to the integrated circuit that corresponds at least one target element among the light emitting elements and the light receiving element, in accordance with a detection temperature …
