PEM-340偏振消光比測試儀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.

• 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
