Optical-electrical module

Abstract

An optical-electrical module includes a base board and an optical transmitting unit fixed on the base board. The optical transmitting unit includes an edge-emitting laser transmitting optical signals parallel to the base board, a driving integrated circuit for driving the edge-emitting laser to transmit optical signals, and a first lens unit for transmitting and converging the optical signals. Furthermore, the optical-electrical module can also include an optical receiving unit used to receive the optical signals transmitted by the optical transmitting unit and convert the optical signals into electrical signals. The optical receiving unit includes a photo diode, a transimpedance amplifier, and a second lens unit.
