Abstract
An optical transmission module includes a light source element for emitting a predetermined light signal transmitted through an optical fiber, the light source element having lower characteristics in a low-temperature state than those in a high-temperature state, a driver circuit for driving the light source element, and a heat transfer member connected to each of the light source element and the driver circuit to transfer heat between the light source element and the driver circuit. The optical transmission module with such configuration can stably operate in a wide temperature range while achieving power saving and cost reduction.
