JW3303 handhold optical variable attenuator is used for continuously variable optical signal attenuation. It supports the 1310/1490/1550/1625nm quad-wavelength and has wide attenuation range from 2.5~65dB.
As the attenuator is used in the laser system for the on-line testing, therefore, JW3303 can be used in the digital system of communication devices (such as: PHD, SDH) and also in the system of adopting analog modulation (CATV)
