MARCH 23, 2009 -- CoreOptics Inc. (search Lightwave for CoreOptics), a designer and manufacturer of 10/40/100-Gbps optical networking subsystems, has announced the validation of the company's algorithm implementation and DSP architecture to achieve what the company believes will enable "the most cost-effective 40G transmission systems" compared to currently available technologies.
"We have had extensive discussions with OEM and carrier customers over the past two years, and we are seeing a rapidly-growing consensus building around the coherent approach to 40G transmission as the only viable solution meeting the cost/performance requirements of carriers," says Hamid Arabzadeh, chairman of the board, president, and CEO at CoreOptics.
"Operators do not like to limit themselves by deploying equipment that has a limited life expectancy and providing an economical 10G-to-40G upgrade path is critical for success," says Ron Kline, research director, optical networks at Ovum (search Lightwave for Ovum). "Vendors, like CoreOptics, who develop and implement DSP-based techniques such as electronic dispersion compensation and coherent detection that enable 40G to operate with the same span lengths and system performance specs as 10G, provide a good fit to market needs."
"Our testing has validated that CoreOptics 40G coherent technology offers disruptive performance increase in CD and PMD impairment mitigation for 40G applications when compared to current modulation schemes incorporating DPSK or DQPSK," says Christoph Schulien, CoreOptics CTO.
CoreOptics currently offers 10-Gbps DWDM, 40-Gbps single-channel short reach, and 40/43G DWDM transponder modules. The company's product portfolio also includes 40G SerDes ICs, 43-Gbps Ultra-FEC, 40G mux/demux for 4x10G client signals, and Interface Converter supporting SFI-5s, SFI-4, and XFI to enable building of next-generation open tolerant networks.
