90% attenuation filter

90%Attenuation filters are like sunglasses, which protect the eyes from strong light by absorbing excess light energy. The optical fiber attenuator can protect the optical fiber by working in a specific wavelength range like sunglasses. The standard for a good fiber attenuator is to replace the reflective fiber by absorbing additional fiber. Because in optical fiber communication, it is necessary to use low optical power without damaging the optical fiber attenuator.
