PEM-340
The PEM-340 polarization extinction ratio (PER) meter enables rapid and accurate polarization axis alignment of optical components to a PMF (Polarization Maintaining Fiber). The PEM-340 incorporates a powerful GPIB interface enabling full system integration and production line automation. In addition, to facilitate automatic alignment of diode lasers to optical fibers, an analog power monitor with 1kHz response time is available. With this addition, both translational and rotational fiber alignment can be controlled automatically.

 

概要

The PEM-340 has two separate versions: the Normal Power version with 50 dB of PER dynamic range is ideal for PM fiber connectorization and alignment of polarization axis of optical devices.
The High Power version has a high input power range of up to +20dBm and is best suited for PMF pigtailed laser diodes evaluation.

 

特徴

  • Full band 1260-1630nm
  • Simultaneous display of extinction ratio, optical power, and polarization angle
  • 50 dB dynamic range for PER measurement
  • Wide dynamic input power range
    (-40 to +10 dBm/Normal power), (-25 to +20dBm/High power)
  • Direct PD analog output
  • Real-time (up to 10Hz) measurement
  • Interchangeable connectors: FC, SC or LC

 

用途

  • Alignment of polarization axis of optical devices
  • Connectorized PMF patch cord evaluation
  • PMF pigtailed laser diodes evaluation
  • PM fiber fusion splicing
