HIGH SPEED OPTICAL CABLE TECHNOLOGY HIGH BANDWIDTH UNIVERSAL CONNECTOR SUPPORTS MULTIPLE PROTOCOLS  10Gb/s to 100Gb/s  single universal replacement for current buses  multiple devices can be connected simultaneously

 TYPES OF BUSES  serial bus and parallel bus  internal bus and external bus  EVOLUTION OF BUS  connects computer components  CONCEPT OF BUS  single shared bus to specialized buses

 SCSI (Small Computer System Interface) used for hard disks and tape drives connects computer and peripheral devices serial bus  FIREWIRE(IEEE 1394 interface ) ( 1995) network cards, sound cards connect hardware devices  CONVENTIONAL PCI (1993) personal computers, digital audio, digital video

 USB (1996)  SATA(Serial Advanced Technology Attachment) (2003)  PCI Express (Peripheral Component Interconnect Express )  HDMI (High-Definition Multimedia Interface)  Display Port serial bus, connects mass storage devices standard connection method serial bus, connect computer peripherals

Today’s Challenges  Electrical I/O nearing practical limits  Devices getting smaller, thinner, and lighter  Speed & distance limited  Too many different connectors & cables

Opportunity: Cost-effective, miniature optical components for mainstream devices  Electrical wires generate field; photons don’t o Length increased o Better interfaces  Light has no mass o Faster transfer  Light Peak implements this optical technology

 SPEED 10Gb/s to 100Gb/s Multiple connection channels  MUTIPLE PROTOCOLS Connect multiple devices simultaneously Universal connector  BI-DIRECTIONAL TRANSFER For upstream and downstream Reduces complexity and cost

 QUALITY OF SERVICE IMPLEMENTATION  Different priority to different applications  HOT PLUGGABLE  Add components without restart  OPTICAL FIBRE BUNDLED WITH COPPER  To power devices

LIGHT PEAK SYSTEM COMPRISES  A fiber optic cable  A controller  An optic module  A connector on each device
