Optical communication module

Abstract

The invention relates to an optical communication module which comprises a light-permeable lens component, a light-permeable fiber fixed part, at least one fiber and a circuit board. The lens component forms a lens structure body, an opening and a light input surface are formed in the top and bottoms sides of the lens structure body respectively, the light input surface is provided with at least one collimating lens, an inclined relation plane and a light output surface are formed in the opposite sides of the lens structure body respectively, the collimating lens is positioned within the orthographic projection scope in the vertical visual angle of the inclined reflection plane, the fiber fixed part is arranged in the side towards the light output surface of the lens component, a dispensing groove is formed in one side of the fiber fixed part, the fiber fixed part is provided with at least one focusing lens, the focusing lens corresponds to the orthographic projection scope in the horizontal visual angle of the light output surface, the fiber penetrates the dispensing groove of the lens component, a fixing glue is filled into the dispensing groove of the lens component, and thus, the fiber is fixed to the lens component, and one end of the fiber is aligned to the position of the focusing lens.

Description

technical field [0001] The invention belongs to the technical field of optical communication modules, in particular to an optical communication module that can effectively improve assembly tolerance tolerance. Background technique [0002] Commonly known optical communication modules, such as China's approved patent case No. 103885140 "optical components and assembly methods for passive coupling of chip arrays and parallel optical fibers", please refer to Figure 7 As shown, it is provided with a photoelectric chip array 500 on a chip carrier 50, and a lens body 51 and a fixing seat 52 are provided on the chip carrier 50, and a reflective surface 510 is provided in the lens body 51, and the lens body 51 is relatively reflective The vertical surface of the surface 510 forms a first lens array surface 511, the lens body 51 forms a second lens array surface 512 relative to the horizontal surface of the reflective surface 510, and the fixing seat 52 is provided with a multi-layer...
