PEM 340

Datasheet

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.

Multiple Simultaneous Measurements

Displays extinction ratio, optical power and polarization angle

High Dynamic Range

Up to 50 dB range for PER measurement

Wide Operating Ranges and Spectrums
Full Band Measurements

Measurements can be done from 1260 nm to 1630 nm

Automated Measurements

Analog monitor at 1kHz response time
