Milpitas, Calif., June 17, 2010 – JDSU (NASDAQ: JDSU and TSX: JDU) today announced the introduction of additional Optical Transport Network (OTN) capabilities to the industry’s most robust 100GE test suite.  With its long history of expertise in OTN, JDSU now offers advanced OTU3 (43GE) and OTU4 (112GE) test features to help transport Ethernet over longer distances for high speed networks.

Optical Transport Networks running on OTU3/4 add the framing, management layer and forward error correction (FEC) on top of Ethernet that is needed for longer distance transmission and for OTN management in a carrier network.  JDSU offers a complete suite of test solutions that gives service providers the confidence to successfully unlock the performance and revenue potential of 40GE/100GE technology. These solutions enable service providers to adopt and install 40GE, 100GE, and OTU3/4 equipment at critical aggregation points to ensure full and seamless validation and verification of interoperability with current equipment and OTU3/4.

JDSU’s fully comprehensive OTU3/4 feature set:

• Provides overhead and payload manipulation as well as monitoring;
• Complements the 40GE/100GE product lines to give complete test coverage;
• Supports comprehensive test features for the new OTL (Optical Channel Transport Lane) layer; and;
• Aligns with JDSU’s existing, industry leading OTU1/2/3 products so customers can easily migrate to the faster speeds.

“With the rapid growth of broadband intensive applications such as cloud computing, more service providers are looking to increase network capacity to 40G and 100G,” said Lars Friedrich, vice president and general manager in JDSU’s Communications Test and Measurement business segment.  “The JDSU OTU3/4 feature set will help network equipment manufacturers seamlessly develop, test and produce their next generation long distance transport products to address these critical issues.”
