SPECIAL POLARIZATION INSTRUMENTS COMPONENTS APPLICATION ACCESSORIES GUIDE FAQS TIMING/DELAY MANAGEMENT MODULES POLARIZATION MANAGEMENT MODULES General Photonics Corporation 909.590.5473 http://www.generalphotonics.com -17- The PolaStayTM polarization stabilizer actively maintains a stable output state of polarization (SOP) against rapid input SOP fluctuations as fast as 2 ms, and tracks against an endlessly rotating input SOP up to 16../s without reset. This unique product is a complete system consisting of General Photonics’ polarization controller, in-line polarization monitor, and proprietary algorithm. The output of the product can either be single mode fiber or PM fiber with the output polarization aligned to its slow axis. When a polarizer is placed at the output, the maximum power fluctuation caused by input polarization fluctuation is less than 0.1 dB. This instrument can be used to suppress noise figure in optical amplifiers, reduce PDL effects, demultiplex polarization division multiplexed channels, and eliminate polarization fading in coherent communication and fiber sensor systems. In addition to the standard configuration, specialized versions are available for low power applications (as low as -30 dBm) and special wavelengths (1064 nm). Specifications: Operating Wavelength Range1 1260 to 1650 nm standard SOP Recovery Time < 7 ms (2 ms typical) SOP Rotation Tracking Speed 16.. /s, endless tracking & reset free SOP Accuracy2 < 0.1 dB Repeatability < 0.1 dB Insertion Loss 0.8 dB typical, 1.2 dB max. Return Loss > 50 dB Isolation in Orthogonal Polarization 20 dB Minimum Optical Input3 -13 dBm standard (low power option available) Optical Power Handling3 20 dBm max. standard (high power option available) Operating Temperature 0 ~ 50 °C Storage Temperature -20 ~ 70 °C Power Supply 100 - 120 VAC, 50 - 60 Hz, or 200 - 240 VAC, 50 - 60 Hz Communication Interfaces RS-232, USB, Ethernet, GPIB Dimensions 2U 19 inch half rack width 3.5” (H) x 8.5” (W) x 14” (L) Notes: Specifications listed above are for the standard configuration; specs may be different for instruments with different wavelength or input power ranges. 1.
