3
What Is Ethernet?

• Most successful LAN technology
• Operates at the Data Link Layer (layer 2) of the
  OSI reference model
• Acts as an interface between the MAC layer and
  transceivers in Ethernet hardware (Physical
  layer)
• Uses contention based medium access protocol
  CSMA/CD

4
Gigabit Ethernet

• Builds on top of the Ethernet protocol
• Allows data transfer speeds of 1000 Mbps
• Provides reliable communication between
  applications of the Network and Transport layers

5
IEEE 802.3 Gigabit Ethernet Specifications

• 802.3z
• 1000BASE-CX (short-haul copper)
• 1000BASE-LX (long-wavelength optics)
• 1000BASE-SX (short-wavelength optics)

• 802.3ab
• 1000BASE-T (twisted pair)
• 1000BASE-LH (long-haul)

6
Benefits of Gigabit Ethernet

• Higher data transfer rates
• Builds on current Ethernet
• Familiar technology
• Minimal staff training

7
Project Aim

• Main Issue Costs associated with opto-electronic
  module
• Project Aim Cheaper module
• Potential Area for Improvement Alignment
  Tolerance

8
Immediate Goals

• Set up test bed for future use
• Test module on evaluation board to confirm
  Gigabit transfer rates
• Test module with Gigabit Ethernet card to confirm
  successful data transfer

9
Research Goals

• Widespread deployment of Gigabit Ethernet to
  homes and residential areas
• Potential for developing other services like
  Video Conferencing
