Abstract
An optical transceiver according to an embodiment includes: a housing having inner sides defining an inner space inside the housing; an optical module including a package, a semiconductor device, and a sleeve, the package being configured to house the semiconductor device, the semiconductor device generating a Joule heat, the sleeve being attached to an outside of the package, the sleeve being fixed to the housing with keeping the package away from the inner sides; a heat-conducting material filled between the package and one of the inner sides, the heat-conducting material including an oily component; and a sheet member being placed between the heat-conducting material and the package, the sheet member covering the heat-conducting material to prevent the oily component from reaching the optical module. The Joule heat is conducted from the package to the housing through the sheet member and the heat-conducting material.
