The PEM-330 provides a simultaneous display of polarization extinction ratio (PER), optical power and polarization angle. These 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.
Features：
- Wavelength range: 1260 – 1630 nm
- Simultaneous display of extinction ratio, optical power, and polarization angle
- 50 dB dynamic range for PER measurement
- Wide dynamic range for input power (-40 to +10 dBm)
- Direct PD analog output
- Analog output
- Real-time (up to 10Hz) measurement
- GPIB and RS-232C interface
Applications：
- Alignment of polarization axis of optical devices
- Connectorized PMF patch cord evaluation
- PMF pigtailed laser diodes evaluation
- PM fiber fusion splicing
