General Photonics, manufacturer of dynamic polarization and timing management, has developed a calibration system for the PSGA-101A polarization measurement system and confirmed that the instrument’s accuracy exceeds that of NIST artifacts. It surpasses all known commercial instruments with regard to repeatability and resolution. PMD affects the reliability of fiber optic data when the transmission speed exceeds 10 Gb/s. Polarization mode dispersion affects the reliability of fiber optic data when the transmission speed exceeds 10 Gb/s. Emerging communication systems operate at 40 Gb/s, and future systems will function at speeds beyond 100 Gb/s. At these high data rates, precise measurement of first- and second-order polarization mode dispersion is critical. For more information, visit: www.generalphotonics.com
