What Is a Fiber-Optic Attenuator?

Fiber optic attenuator is an optical device that can reduce the energy of optical signals. It is used to attenuate the input optical power and avoid distortion caused by the optical receiver due to the excessive input optical power.
Attenuator is like
Parameter unit index < br Working wavelength nm 1310 or 1550
Return loss dB 50
Attenuation and accuracy dB 1 ± 0.5, 2 ± 0.5, 3 ± 0.75, 5 ± 0.75 8 ± 0.8, 10 ± 1, 15 ± 1.5, 20 ± 2.0
Input / output form FC, SC, ST, LC
Temperature range -40 + 80
