Milpitas, California, June 1, 2006 – JDSU today announced the industry’s most complete test solution to ensure Metro Ethernet quality of service (QoS) across core and access networks.  By integrating a set of interoperable field test instruments, network probes and management software, JDSU provides the only single-source solution available to the market for cost-effectively and reliably installing and maintaining Metro Ethernet networks.  It will be on display June 4-8 at GlobalComm 2006 in Chicago (JDSU booth 67040 on level 3, Hall A). 

The solution is the most complete available because it addresses the three primary concerns associated with installing and maintaining Metro Ethernet networks:  the ability to rapidly install new connections, the need to dispatch technicians to fix rather than find problems, and the need for a reliable method to maintain networks while simultaneously reducing truck rolls.  In addition, the solution offers unmatched ease-of-use and straightforward repeatability and consistency of testing.

Multiple industry-leading JDSU products, designed specifically for interoperability to dramatically expand the testing capabilities of the service provider, comprise JDSU’s Metro Ethernet test solution and make it the most comprehensive in the industry.  The products include portable testers like the MTS/T-BERD 8000 and FST-2802 Ethernet tester, as well as the NetComplete Metro Ethernet Service Assurance Solution (consisting of the rack-mountable QT-600 Ethernet IP testhead and centralized NetAnalyst Test OSS). 

“In addition to deployment complexities, managing Metro Ethernet networks becomes a complicated task because next-generation IP services such as IPTV and VoIP expose QoS guarantees to greater scrutiny,” said Helmut Berg, senior vice president of JDSU’s Test and Measurement group.  “Our Metro Ethernet solution enables communications service providers to install the service correctly the first time, reduce mean time to repair and reduce dispatches.  The right test equipment can be the difference between meeting and missing these key deployment metrics.”

NetComplete for Metro Ethernet provides continuous QoS and service availability testing, monitoring and analysis; on-demand and scheduled testing; service turn-up verification; rapid fault isolation and troubleshooting; data filtering using extensive triggers and filter criteria; and multi-interface support (10/100/1000 Mbps via the QT-600).

The MTS/T-BERD 8000 and FST-2802 are portable Ethernet test sets that offer an extensive range of capabilities, ranging from Layer 1 BERT up to Layer 3 installation and maintenance, including loopback capabilities that complement NetComplete for Metro Ethernet. Tests performed during the installation and commissioning include connectivity, throughput, frame loss, and round trip delay (latency). Verifying Ethernet services in this way ensures SLA requirements and, of equal importance, creates a baseline of performance against which the network can be subsequently measured.
