SEPTEMBER 19, 2007 -- CoreOptics (search for CoreOptics), a provider of design and manufacturing of 40- and 10-Gbit/sec optical networking subsystems, has announced application of 10-Gbit/sec maximum likelihood sequence estimation (MLSE) technology for metropolitan WDM platforms.
According to president and chief executive officer Hamid Arabzedah, next-generation metro platforms based on MLSE will offer an adaptive compensation capability that will enable reconfigurable optical add/drop multiplexer (ROADM)-based installed networks to achieve faster service activation time, as well as significant capex/opex savings. "Our company's 10G MLSE equalization technology, 40G IC and transponder solutions will further enable metro WDM platforms to provide more capacity, higher speeds, longer reach, and a greater utilization of optical networks," he says.
"Service providers are continuously looking for higher performance and lower cost in the converged next generation of metro optical networks, says Georg Roell, chief technology officer and cofounder of CoreOptics. "Using advanced digital signal processing technology based on MLSE, CoreOptics has been in the forefront of delivering innovation to help advance the transformation to packet-oriented optical networking and increase the efficiency of existing network infrastructure."
According to the company, system vendors and carriers using CoreOptics tunable DWDM transponders based on dynamic MLSE concept in metro, regional, and long-haul networks can reduce the first-in deployment cost by up to 30% by no longer investing in optical compensators and related amplifiers.
CoreOptics currently offers 10-Gbit/sec DWDM, 40-Gbit/sec single-channel short reach, and 40/43G DWDM transponder modules. The company's product portfolio also includes 43-Gbit/sec Ultra-FEC, 40G multiplexer/demultiplexers for 4x10G client signals, and interface converters supporting SFI-5s, SFI-4, and XFI to enable building of Open Tolerant Networks.
