DWDM core transport technology

Summary form only given. Dense wavelength division multiplexing (DWDM) transmission systems have been used in commercial networks to transport massive data over long distances. The majority of the backbone DWDM systems that are deployed today are point-to-point with limited reach and capacity. To reduce the transport cost per bit and operating cost, new technologies have been developed to transport more bits per second over longer distances with intelligent network flexibility and performance monitoring features. This talk will provide an overview of evolution from today's point-to-point transport networks to next generation reconfigurable high-capacity and ultra long-haul mesh transport networks. Key elements and enabling technologies to build next generation mesh networks will also be reviewed.
