  • Fixed value fiber optic attenuator with index matching material
    Patent number: 5581649
    Abstract: A fiber optic attenuator having a predetermined, fixed attenuation value and low back reflection properties across a broad wavelength spectrum is disclosed. Attenuation is achieved by providing an optical fiber pathway having an attenuation region which causes a predetermined signal loss. The medium defining the pathway is of a substantially constant index of refraction through the device to minimize or eliminate interference caused by Fresnel reflections. An index matching material surrounds the area of attenuation to eliminate or minimize modal or cladding noise.
