Abstract
An optical module for two-way transmission includes a lens for converging a received light from an optical fiber, and a photodiode for sensing the converged received light. A laser diode outputs a transmitted light, and a prism shifts the optical path of the transmitted light converged by the lens, and inputs the transmitted light to the optical fiber.
