INSTRUMENTS POLARIZATION TIMING/DELAY SPECIAL POLARIZATION COMPONENTS MANAGEMENT MODULES MANAGEMENT MODULES High-Speed Polarization State Generator – PolaPal™ General Photonics’ high-speed polarization state generator (PSG) module provides the ability to generate 6 states of polarization (-45°, 0°, 45°, 90°, RHC & LHC) across the Poincaré Sphere in less than 250 μs, with an impressive repeatability of less than 0.1 degrees. In addition, it comes as a compact module ideal for integration into systems that require precise generation of these 6 polarization states or precise 90° polarization rotation. Applications include Mueller matrix-based measurements, polarization OTDR, performance monitoring, and swept frequency component measurement systems. The PSG is easily controlled with a 6-bit TTL signal either from a microcontroller or a computer.
