New! Polarization Extinction Ratio Meter PEM-340

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 a 1 kHz response time is available. With this addition, both translational and rotational fiber alignments can be controlled automatically.

 

Overview

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 20 dBm and is best suited for PMF pigtailed laser diodes evaluation.

 

Features

  • Full band 1260-1630 nm
  • 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 +20 dBm/High power)
  • Direct PD analog output
  • Real-time (up to 10 Hz) measurement
  • Interchangeable connectors: FC, SC or LC

 

Applications

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