September 7, 2004 Nuremberg, Germany--CoreOptics and Marconi announced their cooperation in the launch of a 10-Gbit/sec adaptive distortion tolerant transponder platform with a Maximum Likelihood Sequence Estimator (MLSE) as key building block.

Building on the company's expertise in the development of high capacity optical transport subsystems, CoreOptics' 10-Gbit/sec adaptive distortion tolerant transponder provides performance and cost effectiveness for the next generation of converged networks. The key feature of this product platform is enabled by CoreOptics' MLSE electronic equalization engine that acts adaptively as part of the receiver to compensate for both optical and electrical distortions accumulated along the transmission link.

"Our company's mission is to deliver innovative products to overcome optical layer impairments using advanced digital signal processing techniques" said Hamid Arabzadeh, CoreOptics president and chief executive officer." CoreOptics has been in the forefront of developing highly integrated Electronic Distortion Equalization products based on the Maximum Likelihood Sequence Estimation algorithm, utilizing company's vast intellectual property in the high-speed Analog to Digital converter, Automatic Gain Control, Clock/Data Recovery and Adaptive Distortion Tolerant technologies."

Key benefits of this product platform include reduction in initial capital expenditure, by eliminating the need for the conventional dispersion compensation modules(DCMs) and dual-stage amplifiers. The operational expenditure savings include simplification of network planning, installation, and provisioning by enabling a complete set of plug-and-play features. The distortion tolerant transponder will enable transmission of 10-Gbit/sec services on the widely deployed 2.5-Gbit/sec metro networks, enabling service providers to maximize revenue generation from their installed base.

"I am very pleased to announce our partnership with CoreOptics in defining this truly innovative product that is one of the most critical building blocks of the next generation converged networks," commented Dr. Christoph Glingener, vice president of product technology at Marconi. "Having its roots in a joint project started two years ago, the partnership is a very good example of how two companies sharing the same vision successfully converted an advanced technology into a commercial product. CoreOptics' Distortion Tolerant Transponder will further enhance Marconi's universal cost-optimized multi-haul transport platform across the metro and long haul domains and will unleash the full power of configurable optical networks."

A product demonstration is available at ECOC 2004, held in Stockholm, Sweden; Sept. 7-9 at CoreOptics Booth #356.
