How The Fiber Attenuator Works
Jan 07, 2019

Fiber optic attenuators typically generate light by absorbing light, such as sunglasses, absorbing additional light energy. Similarly, fiber optic attenuators have an operating wavelength range that absorbs light energy, at which point it should not reflect light because This can result in unwanted echo reflections in the fiber system. Another type of fiber attenuator uses a length of high loss fiber to reduce its input optical signal power and operate in this manner.

Its output signal power is less than the input signal power. The optical power is reduced by absorption, reflection, diffusion, scattering, deflection, diffraction, and dispersion of optical signals.
