Automatic Polarization Extinction Ratio Meter
The PERM is a benchtop polarization extinction ratio meter designed for precise measurement of polarization extinction ratio (PER) and polarization angle in polarization-maintaining (PM) fibers, making it ideal for testing PM components and connectors. It supports wavelength ranges from 400 nm to 2500 nm and features a front-panel connection port compatible with FC/PC (narrow- and wide-key), FC/APC (narrow- and wide-key), LC/PC, and SC/PC connectors, with adaptors. Additionally, it has an adaptor option for measuring bare fibers. A push-button operation initiates measurements, displaying PER and misalignment angle, while USB connection enables remote operation and data recording via a user-friendly GUI. The PERM operates using a rotating polarizer in front of a photodiode detector.

System integration
Integration and compatibility
Use these checks to connect Automatic Polarization Extinction Ratio Meter to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optical interface and fiber
- Bare Fiber Adaptor: None, Yes · Connector: FC/PC/APC
- Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
- Wavelength and loss budget
- Wavelength: 900-1650, 1600-2500, 400-900, 357-403, 220-350
- Check the Optical Instruments passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
