CHINO, Calif., May 9, 2011 — General Photonics has announced its PCD-005 fiber optic polarization scrambler module, which uses advanced digital circuitry to deliver a uniform state of polarization distribution, now over a much wider operating temperature range that makes it more suitable for sensor field applications. It features all-fiber technology to effectively randomize polarization states. Designed to be easily plugged into sensor equipment or measurement instruments, it can be remote controlled via RS-232 to set the operation wavelength or enable/disable the scrambling operation. While retaining dimensions and interfaces identical to those of the PCD-004, the PCD-005 delivers low insertion loss, back reflection, and residual phase and amplitude modulation. It can be effectively used for eliminating polarization sensitivity in fiber optic sensor, communication and measurement systems. Insertion loss is <0.05 dB. The center operating wavelengths of 980, 1060, 1310, 1480, 1550 and 1600 nm can be set by remote control via RS-232. The operating wavelength range for each wavelength setting is >100 nm. Output degree of polarization is <5% at a 500-Hz detection bandwidth.
