MARCH 14, 2007 -- JDSU (search for JDSU) has introduced a set of new features for its T-BERD/MTS-8000 fiber optic test instrument. The additions include an in-band optical spectrum analyzer (OSA) that tests network performance; 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 over SONET or SDH (EoS).

"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:

  • 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.

  • A "NewGen" module that enables operators to cost-effectively deliver Ethernet-based services. This all-in-one module is designed to provide 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.

  • The OSA-320, an in-band OSA for the T-BERD/MTS-8000 that incorporates a new method for 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 10 dB 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).
