Fujitsu Introduces Second Generation 40 Gbps Interfaces for its FLASHWAVE® 7500 ROADM

Industry-Leading ROADM Platform Enhanced with Transponder, 4:1 Muxponder, and Regenerator Units

Fujitsu Network Communications Inc.

Richardson, TX, June 08, 2009

Fujitsu Network Communications, a leading supplier of innovative optical and wireless networking solutions, announced today the general availability (GA) of second-generation 40 Gbps interfaces for its market-leading FLASHWAVE® 7500 Reconfigurable Optical Add/Drop Multiplexer (ROADM). Utilizing an innovative Adaptive Differential Phase Shift Keying (ADPSK) modulation scheme and Fujitsu patented Variable Dispersion Compensation (VDC), the second generation units enable network growth up to 1.6 Tbps of capacity to help customers meet ongoing demands for increased speed and bandwidth.

“40 Gbps is one of the highest Optical Networking (ON) growth areas as consumer demand, driven by video, is stressing network capacities,” said Ron Kline, research director of network infrastructure at Ovum. “The 40 Gbps market will grow nearly 90% in 2009 as a new generation of integrated muxponders becomes available and 4x10 Gbps applications dominate deployments.”

Three new 40 Gbps units are now available for the FLASHWAVE 7500 ROADM, including the 40 Gbps Transponder, 4:1 Muxponder, and 40 Gbps Regenerator. Primarily intended for 40 Gbps core router inte rconnection services, the 40 Gbps Transponder provides a full-band tunable network interface and an OC-768 client interface. Supporting four 10 Gbps client interfaces, the 4:1 Muxponder provides an efficient method for aggregating 10 Gbps traffic and quadrupling the capacity of existing 10 Gbps-based networks. The 40 Gbps Regenerator provides electrical signal regeneration for long spans, eliminating the cost and complexity involved with the use of back-to-back transponders.

“As a leading researcher and systems developer in the photonics industry, Fujitsu continues to advance high-speed optical technology and innovation,” said Bill Erickson, senior vice president of planning and development at Fujitsu Network Communications. “With the introduction of our second generation 40 Gbps units we’re improving optical performance and reducing the physical size of the 40 Gbps units by 50% as compared to our first generation 40 Gbps cards previously announced in June 2007. Our sizeable investment in core optical R&D provides Fujitsu with a substantial advantage in the development of high speed photonics.”

All units support ITU G.709 Optical Transport Network (OTN) standards for mapping client signals, optical layer performance monitoring, alarm indication signals, and Enhanced Forward Error Correction (EFEC) for improved optical performance. A Fujitsu-patented VDC device is incorporated into each module, permitting 40 Gbps transmission over wavelengths originally designed to have a maximum speed of 10 Gbps. With this flexibility, network planners who face capacity shortages on existing networks can now effectively increase wavelength capacity fourfold and offer new 40 Gbps services without requiring changes to their existing 10 Gbps wavelengths and networks.

The market-leading FLASHWAVE 7500 ROADM is a complete optical hubbing and transport solution widely deployed in traditional telecom carrier and cable operator networks to support core network consolidation, metro/regional capacity relief, and triple-play service delivery. Globally deployed in North America, Europe, and Asia, the FLASHWAVE 7500 platform is available in ANSI and ETSI configurations. Network topology support spans from simple two-degree (2D) ROADM ring networks to advanced 8-degree optical hubbing/mesh applications. The system supports network sizes of up to 1000 km, up to 24 add/drop nodes per network, and a capacity of up to 1.6 Tbps.

“The explosion of video on demand, advanced multimedia applications and high-speed Internet access are driving new requirements for the network,” added Erickson. “Today’s announcement reflects the surge of video services and high bandwidth applications, and delivers a framework for continuous network evolution to support additional traffic and network demands.”
