Enhancements deliver tools for Next-Generation Networks, including Agile Optical Network (AON), OTN and NewGen field testing

Milpitas, Calif., March 14, 2007 – JDSU today introduced an innovative set of new features for its widely adopted T-BERD/MTS-8000 fiber optic test instrument.  The additions include an in-band optical spectrum analyzer (OSA) that tests Agile Optical Network (AON) performance with a high degree of accuracy; an enhancement for testing Optical Transport Network (OTN) interfaces, enabling users to turn-up and troubleshoot OTN circuits in the field; and a module for testing Ethernet transported over SONET or SDH (EoS), also known as new or next-generation SONET/SDH (“NewGen”) services.  The new features will be showcased at CeBIT 2007 in Hannover, Germany, March 15-21 (hall 13, booth B20) and OFC/NFOEC 2007 in Anaheim, California, March 27-29 (hall C, booth 2425).

In use by every major telecommunications operator worldwide, the JDSU T-BERD/MTS-8000 helps communications service providers and equipment manufacturers meet the fundamental challenges inherent in bringing new network technologies to market, beginning in labs – where verifying network element reliability, interoperability and quality of service (QoS) are paramount – and in the field where the need to reduce installation times, decrease mean-time-to-repair (MTTR) costs, enable efficient maintenance and reduce the overall technology learning curve are a priority.

“The on-demand broadband experience is driving the need for network operators to provide services that are reliable and uninterrupted despite the constantly-changing network environment,” said Dave Holly, senior vice president of JDSU’s Field Service Communications Test and Measurement division.  “JDSU’s T-BERD/MTS-8000, as the industry’s most innovative fiber field test platform, is addressing this need by providing the market with optical test solutions that enable the effective delivery of broadband services.”

The new additions include:

• Optical Transport Network (OTN) capabilities for the T-BERD/MTS-8000 Transport module that enable users to turn-up and troubleshoot OTN circuits in the field that are frequently used as a handoff between operators.   To further ease customer testing procedures, this release also performs monitoring and troubleshooting tasks with Multi Service Transport Platforms (MSTPs) and/or high-end routers, delivers enhancements for lab and production environments including an SCPI interface (remote control) for automated test applications and provides multi-port SONET/SDH/OTN test capability.  These additions strengthen the Transport module’s market leadership position by making it the industry’s most integrated field tester for next-generation services, including OTN technologies for 2.7-11.1G rates. 
• A NewGen module that enables operators to cost-effectively deliver Ethernet-based services.  This all-in-one module provides testing from SONET/SDH to Ethernet layers and complements existing Transport modules in the field by providing virtual concatenation (VCAT) and generic framing procedure (GFP) test functionality.  In addition, link capacity adjustment scheme (LCAS) can be tested using this new module, enabling reliable on-demand increases or decreases in bandwidth.  Inherent in the NewGen module is JDSU’s experience with the technology via the JDSU ONT product line, which has provided these capabilities to the market for over two years.
• The OSA-320, an in-band optical spectrum analyzer (OSA) for the T-BERD/MTS-8000 that incorporates a new method for true optical signal-to-noise ratio (OSNR) measurement in ROADM networks, making it able to test optical performance in the AON.  An AON is a dynamically reconfigurable DWDM network that is designed to accelerate triple-play service deployment, simplify network management, and enable advanced wavelength applications at significantly reduced costs.  In the AON, each channel may traverse different routes, optical amplifiers, and add-drop filters, resulting in different OSNR for each channel.  Conventional OSA measurements are unreliable, as they indicate OSNR values that are too high – up to 10dB above the true OSNR.  JDSU’s OSA-320 follows a new optical polarization splitting (OPS) method for measuring OSNR inside the optical channel (in-band OSNR), providing the highly accurate, true OSNR.

About the JDSU T-BERD/MTS-8000
Combining multiple test capabilities with unprecedented levels of field modularity, JDSU's T-BERD/MTS-8000 is a scalable field platform for provisioning and maintaining short-haul, long-haul, FTTx, Metro, CWDM, transport, data and DWDM networks. Advanced modularity enables the T-BERD/MTS-8000 to integrate options for video microscope, VFL, light source, power meter, and optical talk set with application modules for SONET, SDH, Ethernet, multi-mode and single mode OTDRs, PMD, spectral attenuation, CD, WDM, and single-port and dual-port OSA. Compatibility with more than 10,000 field-proven units already deployed worldwide by every major telecommunications network operator enables easy migration to new network technologies while continuing to reduce expenses.
