Abstract
Official abstract text for this publication.
A photoelectric conversion module includes a substrate, a photoelectric conversion component mounted on the substrate, a wiring pattern formed on the substrate and electrically connected to the photoelectric conversion component, the wiring pattern having a power source line for supplying power to the photoelectric conversion component, a shield cover for covering the photoelectric conversion component, and a first filter inserted into the power source line in series.
First claim
Opening claim text (preview).
What is claimed is: 1. A photoelectric conversion module including only one of an optical transmitter and a photoreceptor, the module comprising: a substrate; a photoelectric conversion component mounted on the substrate; a wiring pattern formed on the substrate and electrically connected to the photoelectric conversion component, the wiring pattern including a power source line for supplying power to the photoelectric conversion component; a shield cover for covering the photoelectric conversion component; and a first filter inserted into the power source line in series for canceling noise on the power source line, wherein the first filter is covered with the shield cover, wherein the photoelectric conversion component has only one of a function of converting an electric signal to an optical signal in the optical transmitter and a function of converting an optical signal to an electric signal in the photoreceptor, and wherein the shield cover is mounted on the substrate and is made of metal, thereby preventing noise from the outside from adversely affecting the photoelectric conversion component or preventing noise from the inside from radiating to the outside, wherein the wiring pattern includes a grounding line for grounding the photoelectric conversion component, the module further comprises a second filter inserted into the grounding line in series, and the second filter is covered with the shield cover for canceling noise on the grounding line. 2. An active fiber-optic cable connected to the photoelectric conversion module according to claim 1 to be optically coupled to at least one end of an optical fiber.
