2000nm single mode Mechanical Variable Optical Attenuator

The 780nm In-line Polarizer is designed to pass light with one specific polarization while blocking the other polarization. It can be used to convert no-polarized light into polarized light with high extinction ratio. It can also be used to enhance the extinction ratio of signals with its excellent polarization properties. It is ideal for high-speed communication systems and test instrumentation where high polarization extinction ratio is required.

Features

  • Low Insertion Loss
  • High Extinction Ratio
  • High Power Handling
  • Low Cost
  • High Reliability

Applications

  • Fiber Amplifiers
  • Fiber lasers
  • Fiber Sensor
  • Test and Measurement
  • Communications System

The 2000nm VOA is a useful tool for the optical components and systems test. The SM Manual Variable Optical Attenuator is designed and manufactured to reduce the output optical power, get the power suitable. It is with low insertion loss, high extinction ration, high return loss and low Adjustment Precision, The SM Attenuator is widely applied at fiber laser system.

Both sizes of VOA are available with a hand twist or a flat-blade screwdriver. The standard size VOA uses an aluminum alloy shell, which is lighter. The nut and the screw are of elastic structure, and the adjustment torque is generated to make the mechanism self-lock, completely eliminate the transmission gap, and the transmission process is stable and five-beat. Thereby, the optical attenuation resolution is high, and the continuity, vibration resistance and stability are better.
