SiOptical Becomes Lightwire

Name change highlights focus on advanced, low-cost optical interconnect products

ALLENTOWN, PA, November 27, 2007 -- Lightwire, Inc., a Pennsylvania-based provider of advanced ultra-high speed interconnect products, today announced that it has changed its name from SiOptical, Inc. to Lightwire, Inc. effective immediately. Lightwire is in the process of bringing to market its first high-speed interconnect products based on its patented silicon photonics technology.

"This name change is an expression of our singular focus on transforming optical interconnects using our advanced silicon photonics-based interconnect technology," said Lightwire CEO Vijay Albuquerque. "But while we have changed our name in order to better communicate our key values, the company, our technology and our team will remain the same."

Lightwire's ultra-high speed interconnect technology is based on Lightwire's silicon photonics technology. Protected by over 120 patents, it is revolutionary in scope yet is fully compatible with Lightwire manufacturing partner Chartered Semiconductor's current high-volume CMOS process technologies. Lightwire expects to bring to market in 2008 a new silicon photonics-based product line that fulfills the high speed, low power and low cost requirements of high-performance interconnects for computing and communications.
