JDS Uniphase Acquires Photonic Power Systems, Inc. JDS Uniphase Innovates Commercial Markets With Pioneering Power Over Fiber Technology SAN JOSE, Calif., June 6 /PRNewswire-FirstCall/ -- JDS Uniphase Corporation (Nasdaq: JDSU; TSX: JDU) announced today it has acquired privately held Photonic Power Systems, Inc., the pioneering provider of photonic power for the delivery of power over fiber. Photonic power is an inventive power delivery system whereby light from a laser source illuminates a highly efficient photovoltaic power converter to produce electrical power. The acquisition represents an innovative system solution to remote powering for many commercial applications. "JDS Uniphase is acquiring a potentially disruptive technology," said Vincent Lui, an analyst with industry research firm IDC. "The technology is not incremental, it is a completely novel approach to power delivery in specialty applications. Moreover, Photonic Power Systems, Inc. has a proven history, strong intellectual property in the area of fiber optic photonic power conversion, and core technology that aligns well with JDS Uniphase's technology base." Photonic power replaces copper and batteries for remote sensors, coaxial cable in wireless applications, and oil or gas-filled measurement transformers in high voltage applications. It delivers isolated power that is immune to RF, EMI, high voltage and lightning. Photonic Power Systems' technology can be leveraged across multiple markets, including medical, wireless communications, electrical power, industrial sensor, and aerospace applications. More than 10,000 units have been deployed to date, serving more than 50 customers. "We're excited about the expanded market opportunities created by this acquisition," said David Gudmundson, vice president of corporate development for JDS Uniphase. "In the long run, we believe customers will include an attractive mix of existing JDS Uniphase communications customers in established sectors such as wireless, and new, diverse industrial customers in applications like remote power and sensing." "Joining forces with JDS Uniphase provides us with a platform upon which to further build this technology and the opportunity to explore new markets and applications," said Dr. Jan-Gustav Werthen, founder and CEO of Photonic Power Systems, Inc. "In addition to access to its optical technology, JDS Uniphase can help us scale via a strong, well-established manufacturing capability and sales channel." "Photonic power has allowed us to easily transition our TV broadcast facilities from analog to digital transmission," said Mr. Yoshikazu Toba, manager of the Ubiquitous Devices Development Division/Networking Devices Operations Unit of NEC TOKIN Corporation. "We intend to utilize this innovative power source for other applications as well including EMI testing of commercial electronics and automotive systems." "Photonic Power Systems' unique photonic power solution has permitted us to offer our electric power customers a very cost effective, low maintenance alternative for current measurement in high voltage environments," said Mr. Georg Wild, director of Engineering Control & Protection, HVDC Systems, Siemens AG. "We look forward to working with JDSU in offering further improvements to our utility customers." All eight of Photonic Power Systems' employees, currently located in Cupertino, California, will transition to JDS Uniphase's corporate offices in San Jose, California. The group will form the nucleus of JDS Uniphase's Photonic Power Business Unit, led by Dr. Jan-Gustav Werthen. Financial terms of the acquisition, which closed on May 26, 2005, are not being disclosed. The acquisition is not anticipated to have a material impact upon EBITDA on a non-GAAP basis. The photonic power technology will be displayed in Booth #736 at Sensors Expo, McCormick Place, Chicago, June 6 - 8. About Photonic Power Systems, Inc.
