1. According to the interface type, it can be classified into SC fiber attenuator, LC fiber attenuator, FC fiber attenuator, ST fiber attenuator.
2. Other categories are online optical attenuators, fixed optical fiber attenuators, and yin and yang optical fiber attenuators.
The optical fiber attenuator can attenuate the input optical power, avoiding the distortion of the optical receiver due to the super strong input optical power
Optical fiber attenuators can be used for debugging optical power performance in optical communication systems, debugging calibration correction of optical fiber instruments, and optical fiber signal attenuation.
In a fiber system with multiple wavelength channels, the optical signal power of each channel needs to be roughly the same, so fiber attenuators are used to equalize the power of each channel.
