Test and Service Assurance Platforms Keep Pace with Market Needs

MILPITAS, Calif., October 2, 2007 - For the next two months at exhibitions throughout North America and Europe, JDSU will display continually expanding capabilities for the industry's most complete Metro Ethernet test portfolio, including several new products addressing one of the industry's fastest-growing technologies. JDSU's portfolio of products enables manufacturers and service providers to address testing and service assurance challenges throughout the Metro Ethernet lifecycle.

JDSU's Metro Ethernet portfolio will be exhibited at the following shows through November 2007: Light Reading Optical Expo 2007, Dallas, October 2-3 (booth 303); Broadband World Forum Europe 2007, Berlin, October 8-11 (booth 1010); Light Reading Ethernet Expo, New York, October 15-17 (booth 416); and Light Reading's The Future of Carrier-Class Ethernet, Warsaw, November 27.

Carrier-grade Metro Ethernet networks are emerging as key components in the delivery of next-generation Ethernet-based business and consumer services (such as triple-play). These networks facilitate service aggregation and work in concert with methodologies that provide common QoS, traffic engineering, redundancy and scalability across the service infrastructure. The result is a complex mix of parameters and requirements which bring many challenges to network equipment manufacturers (NEMs) and service providers, including those associated with verification of network elements, reduction of installation times and mean-time-to-repair (MTTR), and assurance of service availability. The JDSU portfolio is built to address these challenges, providing an integrated, end-to-end approach to test Metro Ethernet products and services, including development and production, installation and maintenance, troubleshooting and overall service assurance.

"Triple play services, including those carried over wireless, are driving the need for high-performance carrier-grade Metro Ethernet networks," said Dave Holly, senior vice president and general manager of JDSU's field service Communications Test and Measurement group. "JDSU is continually updating, investing in and adding new products to our Metro Ethernet portfolio, and we are dedicated to being the preferred test partner throughout the evolution of Metro Ethernet services."

JDSU's Metro Ethernet Portfolio
JDSU's Metro Ethernet portfolio, the most comprehensive in the industry, includes the full range of Ethernet instruments, systems and software required and provides analysis of all seven layers of Metro Ethernet services. Elements of JDSU's Metro Ethernet portfolio are deployed worldwide by most Tier 1 service providers, including telecommunications, cable and wireless network operators.

JDSU offers the industry's only single-source Metro Ethernet test portfolio that facilitates analysis of all seven layers of Metro Ethernet services - the Metro Ethernet deployment "lifecycle" that includes lab and service verification testing. This unique portfolio of broadband-enabling test solutions includes JDSU's MTS/T-BERD 8000, NetComplete for Metro Ethernet (including the QT-600), HST-3000, DA-3400/3600, SmartClass Ethernet, FST-2802, ONT and TestPoint product lines.

JDSU's Metro Ethernet test portfolio also includes the TestPoint product family, part of JDSU's recent acquisition of Innocor, used by leading network equipment manufacturers for verification test and production test up to 10GigE Ethernet LAN/WAN (with and without FEC).
