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.
