Abstract
The optical module includes a main housing to which the optical fiber can be attached and a light-emitting component and a light-receiving component attached to the main housing. At least a part of a surface of the main housing has an irregular pattern to enhance a thermal dissipation. Because at least part of the main housing comprises a heat sink, so the optical module itself has a very high heat dissipation property, eliminating the type of problems that arise when adhesive or the like is used to attach to the main housing heat sinks constituted as separate parts, such as the increase in the number of parts and the degradation in thermal conductivity to the heat sink caused by the adhesive.
