  • Fiber optics signal attenuator
    Patent number: 6222656
    Abstract: An attenuator for use in a wavelength division multiplexer (WDM) uses an opaque knife-edge as a light attenuator. The attenuator is moved along a single axis for controllably blocking the light output of an optical fiber whose light output is to be attenuated. By selectively moving the edge of the attenuator in front of the optical fiber, the attenuator can block any amount of the light output. Multiple attenuators are incorporated in a WDM, each attenuator being used in a channel associated with a particular narrow band of wavelengths.
