Fujitsu launches new Metro DWDM products

May 13, 2002--Fujitsu Network Communications Inc. today launched two new products that it claims will significantly reduce the strain on existing carrier network fiber facilities-the FLASHWAVE 7410 and FLASHWAVE 7420 DWDM platforms.

Fujitsu Network Communications Inc. today launched two new products that it claims will significantly reduce the strain on existing carrier network fiber facilities-the FLASHWAVE 7410 and FLASHWAVE 7420 DWDM platforms. These new metro DWDM solutions can reduce infrastructure costs through capital and operational savings and simplification and dramatically increase bandwidth at a fraction of the cost and time of laying new fiber cable, claim company representatives.

The FLASHWAVE 7420 DWDM platform
The FLASHWAVE 7420 DWDM platform is specifically optimized for metropolitan service providers requiring a flexible, cost-effective system that will multiplex, transport, and switch high-speed voice, video, data, and storage applications. The FLASHWAVE 7420 platform, featuring 32 protected or 64 unprotected DWDM channels, is used for metro core networking, the interconnection of Central Offices (COs), and Points-of-Presence (PoP).

A key differentiator is that this system will directly connect 10-Gbit/sec interfaces without additional equipment--saving space, power and cost. The FLASHWAVE 7420 platform optimizes existing fiber infrastructures and gives carriers a competitive edge says Fujitsu.

The FLASHWAVE 7420 DWDM platform can be used to dramatically increase bandwidth and service flexibility, while supporting new revenue-generating opportunities for high-speed Local Area Network and Storage Area Networking services. The modular architecture of the FLASHWAVE 7420 system comprises a rack-mountable shelf and hot-swappable modules, which perform specific network element functions such as conversion, multiplexing, protection, and network management. The FLASHWAVE 7420 hardware design, coupled with the benefits of DWDM technology, enables the system to support point-to-point, linear add/drop, rin, and meshed network topologies with up to ten nodes.

With the addition of optional optical amplifiers, distances of up to 200 miles (300 kilometers) can be reached. The feature-rich FLASHWAVE 7420 platform allows carriers to deploy broadband optical services over a shared, survivable infrastructure. Individual wavelengths can be provisioned with or without protection to offer multiple Quality of Service (QoS) guarantees at competitive prices.

The FLASHWAVE 7420 protocol independent system is easily adjusted to respond to service changes or network growth, while keeping operational costs down. The system supports all services from 100 Mbits/sec through 10-Gbits/sec. The provisioning of any service at any speed is made more cost-effective by the system's muxponder cards. By removing typical limitations that require dedicated wavelengths for each service, up to 128 services can be transported over a single fiber pair.

The FLASHWAVE 7410 DWDM platform
The FLASHWAVE 7410 DWDM system is a managed wavelength access platform optimized for service providers requiring a network-edge or premises system for delivering voice, data, and high-speed storage applications. Providing a very cost-effective solution, the FLASHWAVE 7410 device is used for managing fiber services between metropolitan area networks and customer premises facilities for business applications, such as LAN and SAN extension, co-location, managed dark fiber services, ATM or SONET/SDH-type circuits, and ASP/ISP metro links. The FLASHWAVE 7410 platform provides a demarcation point between an enterprise local network and the service provider network.

The FLASHWAVE 7410 modular architecture comprises 3 shelf options for holding one, two or 16 hot-swappable modules that can be selected to meet the specific network and application requirements.

The FLASHWAVE 7410 hardware design supports point-to-point and point-to-multipoint network topologies. A 4-channel Coarse Wavelength Division Multiplexing (CWDM) option is also available allowing up to four separate data streams to be carried on a single fiber pair. Many of the card types are available in hot-standby variants allowing operation over a second fiber back-up pair for data-sensitive applications. The sideband management feature monitors and maintains up to 16 separate service links from a common shelf using a single IP address and dramatically reduces the costs associated with multiple management cards, remote connections or maintenance visits.

Fujitsu is currently updating its NETSMART 1500 element management system to fully manage its new FLASHWAVE 7410 and FLASHWAVE 7420 optical transport platforms. To support its focus on optimizing metro optical networking solutions for the North American carrier market, Fujitsu has already submitted these products for Telcordia Technologies' Operations Systems Modification of Intelligent Network Elements (OSMINE) certification--the required certification for installation into COs of incumbent RBOC carriers.
