Fixed fiber optic attenuators are used to reduce the optical power signal in communication links. They work analogous to a step-down transformer. As the signal approaches a device or node in a communication link the power is reduced to a level that is suitable for its application. They are used to control the power level of optical signals at the outputs of light sources and electrical-to-optical (E/O) converters. Measured in decibels (dB), loss degrades signal quality, limits distance, increases bit-error rate, and escalates infrastructure cost. Understanding and managing it is critical to. The Fiber optic attenuator is an optical device that reduces the energy of the optical signal—used to attenuate the input optical power to avoid the distortion of the optical receiver due to the input optical power being too strong. It works by dissipating a portion of the optical power passing through it, thereby lowering the overall power level. Fiber optic attenuators.
