Abstract
In an optical link apparatus of the present invention, a hybrid IC which is a main amplifier of a receiver circuit, and a hybrid IC which is a transmitter circuit are mounted on an island of a lead frame. An OEIC in which electronic devices and a light receiving device which constitute a preamplifier of the receiver circuit are integrated is housed in a light receiving device unit. A light emitting device is housed in a light emitting device unit. Sleeves which are optical link components are installed at the light receiving device unit and the light emitting device unit, and one ends of the sleeves are protruded from a plastic molding to the outside. As wires are connected to lead pins, the hybrid ICs are electrically connected with the light receiving device unit and the light emitting device unit. The lead pins, the hybrid ICs, the light receiving device unit, the light emitting device unit, and the sleeves are integrally sealed by a plastic molding which is superior in productivity and processability. Therefore, the optical link apparatus which is small and superior in productivity can be achieved.
