General Detail
Handhold optical variable attenuator is used for continuously variable optical signal attenuation. As the attenuator is used in the laser system for the on-line testing, there, thereforeJW3303 can be used in the digital system of communication devices (such as:PHD, SDH) and also in the system of adopting analog modulation (CATV)
