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

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

Light Peak
Light Peak is the code name for a new high-speed optical cable technology designed to connect electronic devices to each other. Light Peak delivers high bandwidth starting at 10Gb/s with the potential ability to scale to 100Gb/s over the next decade. At 10Gb/s, we can transfer a full-length Blu-Ray movie in less than 30 seconds. Light peak allows for smaller connectors and longer, thinner, and more flexible cables than currently possible. Light Peak also has the ability to run multiple protocols simultaneously over a single cable, enabling the technology to connect devices such as peripherals, displays, disk drives, docking stations, and more.
Existing electrical cable technology in mainstream computing devices is approaching practical limits for speed and length, due to electro-magnetic interference (EMI) and other issues. However, optical technology, used extensively in data centres and telecom communications, does not have these limitations since it transmits data using light instead of electricity. Light Peak brings this optical technology to mainstream computing and consumer electronic devices in a cost-effective manner.
Light Peak consists of a controller chip and an optical module that would be included in platforms supporting this technology. The optical module performs the conversion from electricity to light and vice versa, using miniature lasers and photo detectors. Over time, the optical components, designed to be small, easy to manufacture and affordable, are expected to enjoy the economies of scale that other components have in the computing and consumer electronics industries.
