Optical communication module and assembling method thereof

摘要

An optical communication module includes a substrate, a lens carrier, and a ferrule. The substrate includes at least two transmitter/receiver chips. The transmitter/receiver chips include plural optoelectronic units with respective alignment marks. The lens carrier includes a frame and a lens array. The lens array includes plural lens units corresponding to respective optoelectronic units of the transmitter/receiver chips of the substrate. The ferrule is coupled with the lens carrier. The alignment marks of the plural optoelectronic units are passively aligned with corresponding lens units, so that the lens carrier and the substrate are precisely aligned with each other and combined together. After the lens carrier and the substrate are combined together, the ferrule and the lens carrier are combined together, so that a precise optical communication path is constructed.
