Optical module

Abstract

The embodiment of the invention discloses an optical module. One side of a shell is provided with an optical receiving adapter and an optical transmitting adapter and the shell is internally providedwith a laser array, a transmitting-end optical multiplexing module and a first displacement prism; one end of a PCB is arranged in the shell, and the laser array is electrically connected with the upper surface of the PCB; the lower surface of the PCB is provided with an optical receiver array; the first displacement prism propagates light from the optical receiving adapter to the lower surface ofthe PCB, and the light then passes through a receiving-end optical multiplexing module and is reflected to the optical receiver array through a reflecting surface; the laser array and the transmitting-end optical multiplexing module are arranged in the shell and corresponding to the upper surface area of the PCB; the received light is propagated to the lower surface of the PCB through the first displacement prism. A component at the receiving end and a component at the transmitting end are located at different sides of the PCB, when the optical module works, no crosstalk happens between the component at the receiving end and the component at the transmitting end, and according to the above layout mode, the utilization ratio of the shell is improved.

Description

technical field [0001] The present application relates to the technical field of optical communication, and in particular to an optical module. Background technique [0002] In the field of optical communication, an optical module is an important device for realizing photoelectric conversion. Such as figure 1 As shown, the optical module generally includes an optical receiver, an optical transmitter and a PCB board.
