Overview

Motorized variable optical attenuator is a fiber-pigtail component, its attenuation can be fixed at the setting value when the voltage added on the motor is off . Its package is very compact and suitable for installation on PCB.

Applications

  • Fiber Optic Communication Systems
  • DWDM Equipment
  • Fiber Optic CATV
  • Local Area Networks (LAN)

Features
  • ALL fiber construction
  • High Reliability
  • Similar to patch cord
  • High Attenuation Accuracy
