General Photonics’ miniature polarization scrambler module, the PSM-002, is specially designed for integration into sensor and communication systems that need to work in extreme environmental conditions. The module uses General Photonics’ patented fiber squeezer technology to effectively randomize polarization states. Unlike that of the PCD-005, the scrambling rate of this miniature scrambler is user selectable via an RS-232 command. Another attractive feature is that the scrambling function can also be enabled and disabled by a TTL trigger signal. The PSM-002 is available either as a standard board for lab applications or fully enclosed in a watertight enclosure for applications in high humidity environments. It also comes in either standard or extended temperature versions.
