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.
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
Today’s Challenges
Electrical i/o nearing practical limits
- speed & distance limited
Devices getting smaller,
thinner, and lighter
Too many different
connectors and cables
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
MAJOR COMPONENTS
OPTICAL MODULE
VCSEL
CONTROLLER CHIP
OPTICAL MODULE
Two way chip
Consists of photo detectors and miniature lasers(VCSEL)
Does conversion from Light to Electricity Vice-Versa
OPTICAL MODULE
VCSEL
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.
Controller chip access the FIS packets from memory
sends these Packets to destination over Optical link
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
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
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.”
CONCLUSION
“ LIGHT PEAK is an high speed optical i/o architecture for the next decade and beyond ”
