Fixed Attenuator
As an optical passive device, the optical fibre attenuator is used for debugging the optical power performance in the optical communication system, debugging the calibration and correction of the optical fibre instrument, and attenuating the optical fibre signal. The product is made of attenuated fibre doped with metal ions, which can adjust the optical power to the required level.
The fixed attenuator is an optical device that can reduce the energy of the optical signal. It is used to attenuate the input optical power and avoid the distortion of the optical receiver due to the super strong input optical power. YOSC's fixed attenuator products include six types: 2dB, 3dB, 5dB, 7dB, 10dB, and 15dB.
