  • 3. INTRODUCTION
    • Light peak is the code name for the high speed optical cable technology
    • It connects electronic devices to each other
    • Delivers bandwidth of 10Gb/s with a potential to scale to 100Gb/s.
  • 4. Features
    • Provide a standard low cost optical based interconnect
    • - support for key existing protocols (USB, HDMI, DP, PCIe , etc)
    • - scalable bandwidth, cost, power to support broad base for
    • 10+years
    • - support wide range of devices(handhelds , laptop , pc’s)
    • Common optical i/o architecture for the next decade and more
    • - single flexible cable that can carry any platform i/o
    • - economies of scale from a single optical solution
  • 5. Today’s Challenges
    • Electrical i/o nearing practical limits
    • - speed & distance limited
    • Devices getting smaller,
    • thinner, and lighter
    • Too many different
    • connectors and cables
  • 6.
  • 7. LIGHT PEAK VS USB 3.0
    • 4 Optical Fibre Cable
    • Speed-10 Gb/sec
    • Universal
    • Max Cable Length-100m
    • 9 Copper Wires
    • Speed-3 Gb/sec
    • Only Usb Protocol
    • Max Cable Length-9m
  • 8.
  • 9. MAJOR COMPONENTS
    • OPTICAL MODULE
    • VCSEL
    • CONTROLLER CHIP
  • 10. OPTICAL MODULE
    • Two way chip
    • Consists of photo detectors and miniature lasers(VCSEL)
    • Does conversion from Light to Electricity Vice-Versa
  • 11. OPTICAL MODULE
  • 12.
  • 13. VCSEL
  • 14. VCSEL
    • The geometry of the dielectric mirrors provide wavelength
    • Thickness of alternating layers d1 and d2 with refractive indices of n1 and n2 if the following equation is satisfied:
    • n1d1 + n2d2 = 1/2 λ
  • 15. CONTROLLER CHIP
    • Manages multiple protocol
    • It Identifies which protocol is to be transmitted
    • API helps to determine the different protocols
    • API places the FIS packets in memory.
  • 16.
    • Controller chip access the FIS packets from memory
    • sends these Packets to destination over Optical link
  • 17. Future Client Usage Models
    • Fast external storage
      • SSD or HDD arrays transferring at 10Gbs and faster
    • Advanced docking
      • High-performance docks, With a single cable, connect to dock with:
    • PC-to-PC high-speed connection
      • Transfer files, PC migration, etc
    • Simplified home connectivity
      • Connect multiple PCs and portable CE devices
  • 18. ADVANTAGES
    • 10 Gbit/s over optical cable (up to 100 metres in length)
    • Connect to multiple devices at the same time
    • Multiple protocols
    • Bi-Directional transfer
    • Quality of service implementation
    • Hot Pluggable
  • 19. Industry Perspective
    • “ 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.”
    • “ 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.”
  • 20. CONCLUSION
    • “ LIGHT PEAK is an high speed optical i/o architecture for the next decade and beyond ”
