Avanex Introduces Next Generation Chromatic Dispersion Compensation Module.New In-Line DCF DCF See: Discounted Cash Flows Solutions Feature Ultra Low Polarization Mode Dispersion Polarization mode dispersion (PMD) is a form of modal dispersion where two different polarizations of light in a waveguide, which normally travel at the same speed, travel at different speeds due to random imperfections and asymmetries, causing random spreading of optical pulses. (PMD (Polarization Mode Dispersion) The type of dispersion that occurs in singlemode fiber due to a lack of perfect symmetry in the fiber and from external pressures on the cable. Light travels over singlemode fiber in two polarization states. ) Making Them Ideal for Emerging High Speed Networks FREMONT, Calif. -- Avanex Corporation (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :AVNX), a pioneering provider of intelligent photonic solutions that enable next-generation optical networks, today introduced a family of new fiber-based dispersion compensation solutions with ultra low PMD, making them specifically tailored to the requirements for emerging, high data rate network applications. "Dispersion compensation fiber (DCF) continues to be the technology of choice for in-line compensation in high data rate networks--for both 40 Gbps and beyond," said Dr. Sanjai Parthasarathi, Senior Director, Product Line Management at Avanex. "For such applications customers want a technology platform that is future proof--channel spacing, bit rate, and modulation format independent. These attributes combined with low group delay and phase ripple make DCF uniquely suited for in-line compensation. With the addition of this low Polarization Mode Dispersion (PMD) family, Avanex is now delivering a new generation of DCF that address causes of impairment beyond the basic inter-symbol interference penalty." Along with the basic pulse spreading impairments that DCMs must compensate, PMD is also a major limitation on high speed transmission (40 Gbps and higher). Since fiber allows two orthogonal modes to propagate at the same time, a speed difference between the two modes results in the receiver detecting a broader pulse, thus leading to impairment. "Given that emerging high data rate applications are very sensitive to PMD, our ultra low PMD dispersion solutions will be highly competitive," Dr. Parthasarathi added. "These new products, with PMD as low as 0.1 ps, represent a significant PMD improvement over other typical industry solutions. We have indications of interest in this product from network system designers at our tier 1 customers."
