Abstract

The invention discloses an optical module. The optical module comprises a housing upper cover, a housing lower cover, an electromagnetic wave shielding layer and a conversion component, wherein a first groove is formed at one end part of the housing upper cover; a second groove is formed at one end part of the housing lower cover; the electromagnetic wave shielding layer is uniformly arranged on the inner walls of the first groove and the second groove; sections of the first groove and the second groove are of a semicircle shape; the conversion component is arranged in a housing formed by connecting the housing upper cover and the housing lower cover; the conversion component is used for installing a round sleeve for switching in an optical fiber in a cylinder hole formed by connecting the first groove and the second groove; and the electromagnetic wave shielding layer fills up a fit clearance of the round sleeve and the cylinder hole. According to the optical module disclosed by the invention, electromagnetic shielding performance after the housing upper cover and the housing lower cover are connected is ensured, and leakage of electromagnetic waves is prevented.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical module. Background technique [0002] An optical module is a key component in the field of optical communication technology, which is used to convert an electrical signal into an optical signal transmittable by an optical fiber, and / or convert an optical signal transmitted by an optical fiber into an electrical signal. Usually, the optical module consists of a housing upper cover, a housing lower cover, and internal devices covered by the housing upper cover and the housing lower cover. The internal devices mainly include circuit boards, conversion components, etc. The conversion components can be light receiving components, light Transmitting components or light transmitting and receiving components. [0003] In recent years, with the development of semiconductor technology and people's demand for large-capacity data transmission and long-distance trans...
