OBJECTIVES

The implemented design which supports bandwidth from

10Gb/s up to 100Gb/s

To confirms its performance, simplicity, and flexibility

This technology is compatible with all communicating devices

It has fast mechanism compare to USB 3.0

5

INRODUCTIONLight peak is the code name

for the high speed optical cable technology

Developed by Intel to connect computing and consumer electronic devices

It allows computers to connect peripheral devices or other computers via an optical connector

6

CONTD…. It is a high-bandwidth, inexpensive optical interconnect

technology

Delivers bandwidth of 10Gb/s with a potential to scale to 100Gb/s

This kind of speed are even sustained over a 100-meter distance, which is really impressive.

LIGHT PEAK TECHNOLOGY

Light Peak is a new high-speed optical

cable technology designed to connect

electronic devices to each other in a

peripheral bus

Light Peak will have fewer and smaller

connectors, longer and thinner cables,

higher bandwidth, and can run multiple

protocols on a single cable

Fig.1: Light Peak Cable

8

CONTD….

The Light Peak cable contains pairs of optical fibers that are used

for upstream and downstream traffic

This means that Light Peak offers a same transmission data rate

in both directions at the same time

The maximum length of the Light Peak cable is 100 meters & it

is made up of plastic layer coating for protection

Intel's Peak light technology interconnect a PC and other

devices, transmitting and receiving data for both PCIe and

Display Ports

11

CONTD….

Peak Light cable is bidirectional.

By this technology, users get the benefit of full bandwidth in

both directions, over a single cable

COMPONENTS OVERVIEW Major components in Light Peak Technology are

1) Optical Module

2) Controller Chip

3) Connector

Fig.6: Components Overview

14

1) OPTICAL MODULE

An optical fiber module is also

called fiber optic transmitter and

receiver

The role of the optical module is

photoelectric

Optical Module is two way chipFig.7: Optical Transceiver Module

15

CONTD….

Either a light emitting diode (LED) or a laser diode is used as

the light source

Consists of photo detectors

In the fiber optics, information is end in the form of pulses of

the light

16

CONTD….

Light Source: The light source is often the most important element

of an optical communication system

There are two types of light sources in widespread use: the Laser

Diode (LD) and the Light Emitting Diode (LEDs)

Light Detectors: Light detectors convert an optical signal to an

electrical signal

The most common light detector is a photodiode

17

2) COTROLLER CHIP

A chipset is a set of electronic

components in an integrated

circuit.

It manages the data flow between

the processor, memory and

peripherals

Chipsets are usually designed to

work with a specific family of

microprocessors

18

DATA TRANSFER SPEED COMPARISION

1) Wireless Network : The Light Peak compare with the latest

technologies, the slowest is wireless

Wireless (802.11) can reach 160 Mb/s in the real world. Light

Peak is about 60 times faster

2) USB 3.0: USB 3.0 is rated at 4.8 Gb/s It will be only half the

speed of Light Peak

9 Copper WiresSpeed-3 Gb/secOnly USB ProtocolMax Cable Length-9m

20

ADVANTAGES

It supports data transfer speed of 10Gbit/s over optical cable (up

to 100 metres in length)

It connects to multiple devices at the same time

Bi-Directional transfer of the data

Cable length can be extended upto 100m

Hot Pluggable

21

DISADVANTAGES

Light Peak technology would required complete new set of

peripheral devices to achieve its parameters

Difficulty of transition from electric to optic & vice versa.

22

APPLICATIONS

Used in the industries to obtain higher data transmission rate

Used to connect peripheral devices with computer for quick data

exchange

23

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.”

24

CONCLUSION

LIGHT PEAK is an high speed optical i/o architecture for the

next decade and beyond
