OPTICAL DEVICE ( VERSIONS ), MODULE OF LASER DIODE, OPTICAL CONNECTOR AND PROCESS OF MANUFACTURE OF OPTICAL CONNECTOR Russian patent published in 1999 - IPC

FIELD: fiber-optical communication lines. SUBSTANCE: proposed optical device includes optical fiber for signal transmission set is lug, optical fiber absorbing scattered light rays, focusing lens and sleeve for precise matching of lug and lens. Butt of absorbing fiber can be polished with inclination. Fibers are set in lug at specified distance multiple of wave length of light signal. EFFECT: reduced noise and losses caused by multiple reflections of light rays in device, simplified manufacturing process and decreased cost of optical device. 21 cl, 11 dwg
