Fiber optic attenuator is an optical device that can reduce the energy of optical signals. It is used to attenuate the input optical power to avoid damage to the receiving equipment due to excessive input optical power. Yingda Optoelectronics can provide fixed attenuators and online adjustable attenuators of different wavelengths.
