Overviews

HD4104 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, therefore, 4104 can be used in the digital system of communication devices (such as: PHD, SDH) and also in the system of adopting analog modulation (CATV)

Feature

  • Portable, rugged, lightweight; Easy to use.
  • displaying dB and dBm attenuating value
  • Attenuating step 0.05dB by circumgyrated dial
  • After off the instruments, the system will have the memorizing of the attenuating value and the attenuating step, in order to restore the system back to the previous shut down state when open the instruments next time
