Redfern Attacks Chromatic Dispersion

EVELEIGH/SYDNEY, Australia -- Redfern Optical Components, a leading supplier of next-generation fiber-based components and subsystems for the worldwide optical networking marketplace, is displaying test results of a dispersion compensator for 512 x 25GHz spaced DWDM channels in a package measuring 2 inches by 7 inches. This device compensates for dispersion of a 70 km long standard optical fiber link within each of 64 channels on 8 separate fibers. In a multiplexed application this new ROC product is able to compensate for dispersion over a 100nm bandwidthRedfern Optical Components' ROC DirectRite(tm) technology gives it unparalleled ability to manage dispersion. The process has also been applied to its high-end filter products with minimal dispersion over the filter bandwidth. These ROC HiFi(tm) filters set a new benchmark for DWDM filters where performance has traditionally been limited by dispersion. "Redfern Optical Components' dispersion compensating product surpasses its competitors in all of the key operating parameters," said the Company's CEO, Dr Allen Conduit. "Fiber Bragg Gratings (FBGs) have been a compelling enabling technology for DWDM, however inherent limitations in the manufacturing techniques employed by the industry have prevented their widespread use in dispersion compensation and other high performance applications. Our dispersion compensators overcome the two most significant problems faced by traditional FBG manufacturers - managing more than just a single channel, and managing the amount of distortion introduced onto the data being carried."
