A fixed attenuator is a precision optical device with a fixed amount of fiber attenuation. The attenuation of optical power is achieved according to the pre-designed attenuation of the line. Products are used in a variety of fiber optic transmission lines.
Flange type fixed attenuators: FC type, SC type, LC type, etc.; attenuation amount: 3, 5, 7, 10, 15dB and other grades.
Yin-yang fixed attenuators: FC type, SC type, LC type, etc.; attenuation amount: 3, 5, 7, 10, 15dB and other grades.
2. Product characteristics
Attenuation accuracy: ±10%
Working wavelength: 1310 and 1550
Return loss: ≥50dB (PC), ≥60dB (APC)

3. The fiber attenuator test system has the characteristics of high attenuation precision, low additional loss and good stability.
Main applications: fiber optic communication systems; fiber optic CATV; high power optical device measurement;
It is used to attenuate the input optical power and avoid the distortion caused by the optical receiver due to the strong input optical power.
