Polarization Extinction Ratio Measurement

Polarization Extinction Ratio Meter

PEM-340

Rapid & Accurate measurement for PER, Angle, and Power

  • 50 dB Dynamic Range for PER Measurement
  • Wide Dynamic Input Power Range
  • Interchangeable Connectors: FC, SC or LC
PEM-340

Our PEM-340 polarization extinction ratio (PER) meter enables rapid and accurate polarization axis alignment of optical components to a Polarization Maintaining Fiber (PMF). In addition, to facilitate automatic alignment of diode lasers to optical fibers, an analog power monitor with a 1 kHz response time is available.

  • Full band 1260 to 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
  • Alignment of polarization axis of optical devices
  • Connectorized PMF patch cord evaluation
  • PMF pigtailed laser diode evaluation
  • PM fiber fusion splicing
