Variable Fiber Optical Attenuator are mainly used in fiber optic to debug optical power performance & optical instrument calibration correction & fiber signal attenuation to ensure the optical power in a stable and desired level in the link without any changes on its original transmission wave.
Low insertion loss
Low PDL
Wide attenuation range from 0dB to 60Db
High stability and high reliability.
LAN
Telecommunication
CATV system
Digital multimedia transmission system
