Product information "PSG-001 Polarization State Generator"
1260-1620 nm; IL 1.0, 1.2 dB; WDL ≤0.3 dB; Switching Speed ≤250 µs; Repeatability ±0.1°; RL ≥55 dB
General Photonics’ PSG-001 high-speed polarization state generator (PSG) module generates six states of polarization (-45°, 0°, 45°, 90°, RHC & LHC) across the Poincaré sphere in less than 250 μs, with a repeatability of less than 0.1 degrees.
In addition, PSG-001 comes as a compact module ideal for integration into systems that require precise generation of these six polarization states or precise 90° polarization rotation. The PSG-001 polarization state generator is easily controlled with a 6-bit TTL signal either from a microcontroller or a computer.

PSW-002 Polarization Switch
1310, 1550 nm; IL <0.5 dB; Switching Speed 100 µs; Polarization Rotation 45°, 90°; ER >18 dB; RL >55 dB
General Photonics’ PSW-002 is a solid-state polarization switch that can quickly and repeatably rotate the state of polarization (SOP) of incoming light by a fixed angle, either 45° or 90°. Both single mode (SM) and polarization maintaining (PM) fiber pigtailed versions are available.
With the PM option, the PSW-002 device functions as a TE to TM converter, switching the SOP between being aligned with the slow and fast axes of the PM fiber, or between the slow axis and 45° from the slow axis. With the SM option, the device simply rotates the polarization ellipse either 45° or 90°.
The device can be used for polarization sensitive OCT, polarization sensitive OTDR or OFDR, PMD monitoring, polarization modulation, polarization detection, and polarization metrology. An optional driver board simplifies switch control by allowing the user to control the output SOP using TTL levels.
