Manufacturers : Optoelectronics : Fiber optics : Fiber optic attenuators

Fiber optic attenuators are optical components that induce a calibrated loss between two connectors to dampen an optical signal. Fiber optic attenuators are required in cable television, communication networks such as fiber optic telephone networks and the like, to attenuate light transmitted through fiber optic bundles at selected locations. Optical fiber attenuators may be used to simulate attenuation losses over long distances or to reduce energy levels in a network between a transmitter and a receiver. Fiber optic attenuators reduce the amount of power present in an optical signal. Fiber optic variable attenuators are fiber optic attenuators in which the amount of this reduction may be adjusted. Excessive signal power can cause saturation at the receiver and induce system errors and failures. Fiber optic attenuators induce a calibrated fixed loss between two connectors, which dampens (attenuates) the fiber optic signal. Attenuation is desirable if the optical signal has a power level that exceeds the operating range of the equipment to which the signal is being transferred. Without attenuation, the result can be saturation of the signal and induction of system errors or failures. Attenuation is typically achieved by passing the signal through an absorption filter or an air gap. Conventional fiber optic attenuators are available in bulkhead, in-line and build-out configurations.
