JW3303 Handheld Optical Variable Attenuator
JW3303 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).
Key Features and Applications of JW3303 VOA
Attenuation step: 0.05dB | dB and dBm attenuating value can be displayed |
Auto-off within 10 mins no-operation | Attenuation value and step can be memorized after off the instruments |
Protable | Rugged |
Lightweight | Easy to use |
With the above excellent characteristics, the JW3303 handheld optical variable attenuator can be used for maintenance in telecom system and CATV system. It can be applied to optical instruments research and development, optical communication education and lab testing and other optical project.
