Fujitsu Introduces New Multiservice Access Options for its FLASHWAVE® 4020 ESP

Separate Interface Modules Support Long Reach, Intermediate Reach and CWDM Requirements for Converged Broadband Access Networks

June 14, 2005

Fujitsu Network Communications Inc., a leading supplier of IT and wireline/wireless networking solutions, today announced an upgrade to its multiservice FLASHWAVE® 4020 Ethernet Service Platform (ESP) to support Small Form-factor Pluggable (SFP) interfaces. New SFP-based OC-3 and OC-12 base unit shelves are now available, and each can be equipped with matching-rate SFP modules to support Long Reach (LR), Intermediate Reach (IR) and Coarse Wavelength Division Multiplexing (CWDM) requirements for converged access networks. Since these SFP modules can be easily interchanged, networks can be upgraded and maintained more conveniently than with traditional optic modules, resulting in substantial Operating Expense (OPEX) cost savings.

The updated FLASHWAVE 4020 ESP will be showcased and discussed this week along with other scalable and reliable triple-play solutions in Fujitsu Booth No. 527 during the Society of Cable Telecommunications Engineers (SCTE) Cable-Tec Expo 2005 tradeshow. The exhibition runs from June 15 through June 17, 2005 at the Henry B. Gonzalez Convention Center in San Antonio, Texas.

“Today’s small-to-medium business customers require solutions that offer both DS1 and Ethernet services to support today’s most popular services,” said Bill Erickson, senior vice president of sales and marketing at Fujitsu Network Communications. “DS1 services are the most commonly used access method for PBX voice services and Frame Relay data services, while Ethernet offers the best option for router interconnection. With the FLASHWAVE 4020 ESP, carriers can deliver both of these dominant services simultaneously from the same device, while offering all the proven reliability of SONET.”

The addition of SFP interfaces gives service providers more options for flexible access networks. The new CWDM capabilities allow carriers to get additional capacity from their fiber plant and add services to business customers along existing fiber routes.

For CWDM applications, up to eight separate OC-3 or OC-12 SONET signals can be transported over a single fiber pair, offering an 8x increase in the capacity of existing optical access networks. Individual SFP-based optics for the FLASHWAVE 4020 ESP support wavelengths that are compatible with the standard International Telecommunication Union (ITU) G.694.2 CWDM grid to allow full interoperability with standards-based CWDM equipment. This capability allows the FLASHWAVE 4020 ESP to be connected to commercially available CWDM passive couplers such as the FLASHWAVE 7120 optical extension system or FLASHWAVE 7410 CWDM access system. The FLASHWAVE 4020 ESP can also utilize commercially available aerial mount CWDM couplers to support easy connections to MSO master headends and primary/secondary hubs.

The FLASHWAVE 4020 ESP supports both seven DS1 and four 10/100Base-T Ethernet services over a protected or unprotected OC-3 or OC-12 SONET network interface. The device’s compact 1U (1.75″) height, low cost, minimal power requirements and advanced protection options, make the FLASHWAVE 4020 ESP a popular choice for delivering today’s next-generation voice and data services. The two new base unit configurations with SFP optic options support highly flexible designs, easy installation, and a simplified inventory process.
