Optical fiber attenuator is a kind of optical device which can reduce the energy of optical signal. It is used to attenuate the input optical power and avoid the production of the optical receiver due to the input optical power being too strong
The distortion of birth. As an optical passive device, it is used in optical communication system to debug optical power performance, debug optical fiber meter calibration, optical fiber signal attenuation. The product is made of damped optical fiber doped with metal ions, which can adjust the optical power to the desired level.
