    Abstract: An optical module including a matching circuit and a connector is provided. The matching circuit of the optical module achieves an impedance matching with the active elements. The connector of the optical module includes two electrical contact points with inner active elements and an external circuit board. One contact point to be electrically connected to the external circuit board protrudes from the back surface of a package parallel to an optical axis. The optical module of the present invention is easily attached and detached to and from an optical communication system, and has a high-frequency characteristic of minimizing signal loss and interference between signals.
