GAOTek Optical Fiber Tester Variable Attenuator

GAOTek optical fiber tester variable attenuator is used for continuously variable optical signal attenuation.

GAOTek-OPA-120

Description

Overview

GAOTek optical fiber tester 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, VOA-M1 can be used in the digital system of communication devices and in the system of adopting analog modulation (CATV).

 

Features

  • Stepwise attenuating by circumgyrated dial attenuating step 0.05 dB
  • Provide with the function of displaying dB and dBm attenuating value
  • 10 minutes Auto-off function can be activated
  • Deactivate with keypad operation.
  • The system will have the memorizing of the attenuating value
  • Portable, rugged, lightweight and Easy to use
