Polarization Extinction Ratio Meter PEM-330

Real Time PER Monitor

PEM-330
The PEM-330 is a high‐performance polarization extinction ratio meter with 50dB dynamic range for per measurement and very high accuracy. The PEM-330 provides a simultaneous display of polarization extinction ratio (PER), optical power and polarization angle.

 

Overview

PER, optical power and polarization angle are the three critical parameters required when aligning polarization maintaining fiber to optical devices. The instrument is thus suitable for component manufacture as well as evaluation. It also has communication ports to allow fully automatic fiber alignment and measurement.
The PEM-330 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.

 

Features

  • Full band 1260-1630nm
  • Simultaneous display of extinction ratio,
              optical power, and polarization angle
  • 50dB dynamic range for PER measurement
  • Wide dynamic range for input power (-40 to +10dBm)
              High input power version (-25 to +20dBm) is available.
  • Direct PD analog output
  • Real-time (up to 10Hz) measurement
  • Option utility software
              (for controlling instrument and acquiring/storing data)

 

Applications

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