Abstract

The invention discloses an optical module. The optical module comprises a shell, a substrate arranged in the shell, an optical device arranged in the shell, and a plurality of light emitting elementsand a plurality of light receiving elements which are arranged on the substrate; the plurality of light emitting elements and the plurality of light receiving elements are arranged between the opticaldevice and the substrate; the optical device is arranged above the plurality of light emitting elements and the plurality of light receiving elements; the optical device comprises a device body, andan optical transceiving interface and a lens array which are arranged on the device body. Optical signals emitted by the plurality of optical emitting elements are transmitted to the outside of the optical module through the optical transceiving interface. Optical signals transmitted from the outside of the optical module reach the plurality of optical receiving elements through the optical transceiving interface, the lens array can enable the plurality of optical transmitting elements and the optical transceiving interface to be optically coupled and the optical transceiving interface and theplurality of optical receiving elements to be optically coupled, and an auxiliary lens is arranged on an optical coupling path. The light divergence angle is reduced, and higher coupling efficiency is obtained.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical module. Background technique [0002] In recent years, optical interconnection technology has been widely used, which is a technology for transmitting signals at high speed within system equipment and between equipment or between optical modules. That is, optical interconnection is a technology that treats optical devices as electrical components and mounts optical devices on motherboards or circuit substrates, such as those used in personal computers, vehicles, and optical transceivers. [0003] With the rapid development of technology, optical communication modules are required to have faster transmission rates and lower costs, requiring modules with the same density to have several times the communication rate and communication volume. At present, multi-mode is mostly carried out in multi-channel parallel mode, but its cost is high, and the transmissi...
