NEC Chooses Xilinx Virtex-4 FPGAs for 40 Gbps WDM

NEC is using Xilinx's Virtex-4 FX FPGA for its SFI-5-compliant 40 Gbps WDM optical communications systems.



NEC's SpectralWave DW4200 series of WDM reconfigurable optical add/drop multiplexers (ROADM) achieves 40 Gbps over existing fiber and is capable of multiplexing of up to 80 wavelengths.



The Xilinx Virtex-4 FX60 device chosen by NEC supports all major serial standards including PCI Express, Serial RapidIO, Ethernet and Fibre Channel, enabling the design of multiple applications using the same device, thereby reducing total solution cost. Virtex-4 FX RocketIO transceivers provide advanced equalization features, such as 3-tap Transmit Pre-emphasis, Linear Receive Equalization, 6-tap Decision Feedback Equalization (DFE), and Integrated AC-coupling capacitor, to enhance signal integrity at all speeds over the most stringent channels.
