Large-offset optical contact, optical interconnection assembly and long-distance space optical communication system

Abstract

The invention relates to a large-offset optical contact, an optical interconnection assembly and a long-distance space optical communication system, and the large-offset optical contact comprises a lens which is arranged at the front end and is used for focusing or expanding a received light beam, and a positioning hole which is arranged at the rear end and is used for coupling and positioning a pin part. And further included is a prism used for realizing light path conversion between the pin component and the lens. When the two large-offset optical contacts realize large-offset active optical transmission, the pin parts in the tail positioning holes are connected through an optical cable, and the front-end lenses are respectively arranged corresponding to the spatial light emitting module and the spatial light receiving module to realize emission and receiving of spatial light; when the two large-offset optical contact pieces realize large-offset passive optical transmission, the tail pin parts of the two contact pieces are respectively connected with the optical transmitting device and the optical receiving device through cables, and the front-end lenses are oppositely and coaxially arranged to respectively perform beam-expanding transmitting and receiving focusing of light. According to the contact piece, the axial distance is shortened, the structure is flattened, the space is saved, and the contact piece is applied to a limited environment.

Description

technical field [0001] The invention belongs to the technical field of optical transmission, and in particular relates to an optical interconnection assembly of a large offset optical contact and a long-distance space optical communication system. Background technique [0002] When existing active modules or passive devices transmit spatial light, the distance between the transmitting end and the receiving end is often limited by the distance between the transmitting end and the receiving end, which cannot meet the requirements of long-distance transmission. Moreover, there are strict requirements on the relative position and angle of the transmitting end and the receiving end. Therefore, how to realize the long-distance transmission of spatial light and how to realize the large-scale adjustment of the transmitting and receiving ends in terms of distance and angle are urgent problems to be solved. . Contents of the invention [0003] In order to solve the above problems, ...
