ABSTRACT:
An optical device comprises a signal transmission optical fiber for transmitting an input light signal to an output port, a scattered light rays absorbing optical fiber for absorbing multiply reflected light rays generated in the optical device, a ferrule for fixedly holding the signal transmission optical fiber and scattered light rays absorbing optical fiber, a lens for focusing the input light signal transmitted through the signal transmission optical fiber, and a sleeve for fixedly aligning the ferrule and the lens, thereby preventing the reflected light rays from being fed back to the signal transmission optical fiber.
