Todays Challenges

Electrical I/O nearing practical limits

Devices getting smaller, thinner, and lighter

Speed & distance limited

Too many different connectors & cables



4/30

Opportunity: Cost-effective, miniature optical

components for mainstream devices

Electrical wires generate field; photons dont

oLength increased

oBetter interfaces

Light has no mass

o Faster transfer

Light Peak implements this optical technology

Sony is excited about the potential for Light Peak technology that has beendeveloping, and believe it could enable a new generation of high-speed deviceconnectivity.

Nokia believes that Light Peak technology enables new wired connectivitysolutions for Mobile Computers and Smart phones, and looks forward to workingto create a global standard based on Light Peak technology.

"We're thrilled to collaborate with Intel to bring the groundbreaking Thunderbolt

technology to Mac users. With ultra-fast transfer speeds, support for high-resolution displays and compatibility with existing I/O technologies, Thunderboltis a breakthrough for the entire industry and we think developers are going tohave a blast with it."

Bob Mansfield, Senior Vice President of Mac Hardware Engineering,

Apple Inc.
