  3. 3. INTRODUCTION <ul><li>Light peak is the code name for the high speed optical cable technology </li></ul><ul><li>It connects electronic devices to each other </li></ul><ul><li>Delivers bandwidth of 10Gb/s with a potential to scale to 100Gb/s. </li></ul>
  4. 4. Features <ul><li>Provide a standard low cost optical based interconnect </li></ul><ul><li>- support for key existing protocols (USB, HDMI, DP, PCIe , etc) </li></ul><ul><li>- scalable bandwidth, cost, power to support broad base for </li></ul><ul><li>10+years </li></ul><ul><li>- support wide range of devices(handhelds , laptop , pc’s) </li></ul><ul><li>Common optical i/o architecture for the next decade and more </li></ul><ul><li>- single flexible cable that can carry any platform i/o </li></ul><ul><li> - economies of scale from a single optical solution </li></ul>
  5. 5. Today’s Challenges <ul><li>Electrical i/o nearing practical limits </li></ul><ul><li>- speed & distance limited </li></ul><ul><li>Devices getting smaller, </li></ul><ul><li>thinner, and lighter </li></ul><ul><li>Too many different </li></ul><ul><li>connectors and cables </li></ul>

  9. 9. MAJOR COMPONENTS <ul><li>OPTICAL MODULE </li></ul><ul><li>VCSEL </li></ul><ul><li>CONTROLLER CHIP </li></ul>
  10. 10. OPTICAL MODULE <ul><li>Two way chip </li></ul><ul><li>Consists of photo detectors and miniature lasers(VCSEL) </li></ul><ul><li>Does conversion from Light to Electricity Vice-Versa </li></ul>
  11. 11. OPTICAL MODULE
  12. 12.
  13. 13. VCSEL
  14. 14. VCSEL <ul><li>The geometry of the dielectric mirrors provide wavelength </li></ul><ul><li>Thickness of alternating layers d1 and d2 with refractive indices of n1 and n2 if the following equation is satisfied: </li></ul><ul><li>n1d1 + n2d2 = 1/2 λ </li></ul>
  15. 15. CONTROLLER CHIP <ul><li>Manages multiple protocol </li></ul><ul><li>It Identifies which protocol is to be transmitted </li></ul><ul><li>API helps to determine the different protocols </li></ul><ul><li>API places the FIS packets in memory. </li></ul>
  16. 16. <ul><li>Controller chip access the FIS packets from memory </li></ul><ul><li>sends these Packets to destination over Optical link </li></ul>
  17. 17. Future Client Usage Models <ul><li>Fast external storage </li></ul><ul><ul><li>SSD or HDD arrays transferring at 10Gbs and faster </li></ul></ul><ul><li>Advanced docking </li></ul><ul><ul><li>High-performance docks, With a single cable, connect to dock with: </li></ul></ul><ul><li>PC-to-PC high-speed connection </li></ul><ul><ul><li>Transfer files, PC migration, etc </li></ul></ul><ul><li>Simplified home connectivity </li></ul><ul><ul><li>Connect multiple PCs and portable CE devices </li></ul></ul>
  18. 18. ADVANTAGES <ul><li>10 Gbit/s over optical cable (up to 100 metres in length) </li></ul><ul><li>Connect to multiple devices at the same time </li></ul><ul><li>Multiple protocols </li></ul><ul><li>Bi-Directional transfer </li></ul><ul><li>Quality of service implementation </li></ul><ul><li>Hot Pluggable </li></ul>
  19. 19. Industry Perspective <ul><li>“ Sony is excited about the potential for Light Peak technology that has been developing, and believe it could enable a new generation of high-speed device connectivity.” </li></ul><ul><li>“ Nokia believes that Light Peak technology enables new wired connectivity solutions for Mobile Computers and Smart phones, and looks forward to working to create a global standard based on Light Peak technology.” </li></ul>
  20. 20. CONCLUSION <ul><li>“ LIGHT PEAK is an high speed optical i/o architecture for the next decade and beyond ” </li></ul>
