What Are the Common Fiber Optic Attenuators?
Fixed optical attenuator is an optical device that can reduce the energy of optical signal. Through the attenuation of input optical power, it can avoid the distortion of optical receiver due to too strong input optical power. As an optical passive device, fiber attenuator is usually made of attenuation fiber with metal ions. It can adjust the optical power to the required level. It is mainly used in optical communication system to debug the optical power performance, calibrate the calibration of optical fiber instrument and reduce the attenuation of optical fiber signal. 1. Why use fiber optic attenuators? The intensity of optical signal received by various optical receiving equipment is limited, and the equipment can not work normally if the optical power is too weak or too strong within a certain range. When the optical power is too strong, the optical power will be adjusted by light attenuation to reduce it to an appropriate range, otherwise even if the equipment can be...
