Abstract

Provided is a photoelectric conversion module group which comprises a photoelectric coupling piece, a bridge-connecting device and multiple optical fibers. The photoelectric coupling piece can be detachably installed on the bridge-connecting device. The photoelectric coupling piece is provided with multiple first coupling lenses. The bridge-connecting device comprises a first external side surface, a second external side surface, a first end surface and a second end surface. The second external side surface extends towards the first external side surface so that multiple aligning holes are arranged, and the multiple optical fibers are respectively accommodated in the multiple aligning holes. The first end surface extends towards the first external side surface so that an inclined surface which is inclined is formed. One angle is formed by the first end surface and the inclined surface. The second end surface is also provided with a groove. The bottom part of the groove is provided with multiple second coupling lenses which are corresponding to the first coupling lenses. Each second coupling lens is arranged on an optical path which corresponds to the optical signal of the corresponding optical fiber and is reflected by the inclined surface. Each second coupling lens is correspondingly aligned with one first coupling lens. According to the photoelectric conversion module group, the optical path is easy to align.

Description

technical field [0001] The invention relates to a conversion module, in particular to a photoelectric conversion module. Background technique [0002] The photoelectric conversion module is used to connect the optical signal transmitting device and the optical fiber or between the optical fiber and the optical signal receiving device to realize the coupling of the optical signal and the mutual conversion between the optical signal and the electrical signal. Existing photoelectric conversion modules are used to bend the surface-emitting laser by 90 degrees to transmit energy to the optical fiber, or to bend the light transmitted by the optical fiber by 90 degrees to be received by the photodetector. The photoelectric conversion module is usually realized by using a lens made of high refractive index material with an angle of 45 degrees. This approach can effectively deflect the light and make the module smaller. However, in this structure, the lens is difficult to manufactur...
