Miniature Polarization Scrambler Card
General Photonics’ miniature polarization scrambler module is designed specifically for hand held and
field instruments. It uses fiber squeezer technology to effectively randomize polarization states.
Unlike the PCD-003 and PCD-004, the scrambling rate of this miniature scrambler is user
selectable from a few hertz to tens of kilohertz via a push-button switch. Its low power
consumption, as low as half a watt, enables the module to be powered by batteries. Its
miniature size (3” x 4” x 0.8”) allows it to be easily integrated in the tight spaces typical
of handheld instruments. Finally, the scrambler has a superb scrambling uniformity
enabled by an on board microprocessor and proprietary codes.
