CHICAGO -- NEC America, Inc.(NEC), a leading provider of carrier-class communications products for optical networksannounced today, the SpectralWave™ DW4240 Core/Edge reconfigurable optical add/dropmultiplexer (ROADM). The new network device delivers dynamic bandwidth allocation ofnetworked wavelengths with integrated transport, switching and multi-layer management at boththe wavelength and SONET/SDH layers. Easy to deploy, and offering an efficient, reliablenetwork operation system with advanced end-to-end wavelength provisioning, the NEC 4240saves carriers on operational and capital expenditures (OPEX/CAPEX) and helps increaserevenues by bringing high-speed services quickly to market.

As the first solution in NEC’s new-generation optical networking platform, the NEC 4240 helpsnetwork operators overcome the design limitations of conventional metro dense wavelengthdivision multiplexing (DWDM) systems. As an intelligent, automated solution, the NEC 4240provides the support and network reliability necessary to deliver Gigabit Ethernet and completevoice, video and data triple-play services, including: Internet Protocol Television (IPTV) andVideo on Demand (VOD) applications. Network operators will realize benefits in operationalsimplicity and lower operational expenses, as well as CAPEX savings in initial deployment andsparing costs.

“NEC is truly treating the ROADM as a market segment, and is delivering, as promised, aplatform that is not a simple extension of legacy DWDMs, but the base for the next generationoptical add/drop applications at all line rates,” said Rocky Kler, general manager, OpticalNetwork Systems Division, NEC. “We see the 4240 as the first of several steps in our newgenerationoptical networking plan, designed to meet carriers’ desire to optimize their networkboundaries.”

Specifically, the NEC 4240 is a very compact system that offers full ROADM capability forflexible multiplexing and transport of up to 40 C-Band or L-Band optical wavelengths. The NEC4240's feature set includes full add-drop capability at any node, full-band tunable transponders,integrated SONET-on-a-blade multiplexers, and upgradeability to wavelength cross-connect(WXC) configuration. Transport topologies supported by the NEC 4240 include optical rings,point-to-point, and linear-chain.

The NEC 4240 uses a single universal ROADM shelf type to support ROADM, Terminal, and In-Line Amplifier configurations. Both the Terminal and In-Line Amplifier configurations can beupgraded in-service to full ROADM configuration by simply adding units.

The NEC 4240 is the first available product in NEC’s new-generation optical transport system.NEC plans to rollout additional products, services and software throughout FY2005 and FY2006.The NEC 4240 is generally available, with pricing approaching SONET mux levels in a basicconfiguration.
