10Mbps Ethernet

  • Legacy Ethernet
    • 10BASE5, 10BASE2, and 10BASE-T
  • Four common features:
    • timing parameters
    • frame format
    • transmission processes
    • basic design rule

10BASE

  • transmitted 10 Mbps over a single link coaxial cable bus
  • part of the original 802.3 standard
  • uses Manchester encoding
  • runs in half-duplex with a maximum transmission rate of 10

10BASE

  • exists in legacy networks
  • uses Manchester encoding
  • uses half-duplex with a maximum transmission rate of 10 Mbps
  • up to 30 stations on a 10BASE2 segment

100Mbps Ethernet

  • Known as Fast Ethernet
  • 100BASE-TX (copper UTP)
  • 100BASE-FX (multimode optical fiber)
  • Both Share:
    • timing parameters, the frame format, and parts of the transmission process
  • encoding uses a technique called 4B/5B
    • Converts each set of 4 bits into a 5 bit pattern
    • Improved error detection
    • Simplified transmitter and receiver design

100BASE-TX

  • using Category 5 UTP cable
  • Uses 4 wires (2 pair)
  • uses 4B/5B encoding, which is then scrambled and converted to Multi-Level Transmit (MLT-3) encoding
  • 100Mbps of traffic in half-duplex mode
  • 200 Mbps of traffic in full-duplex mode

1000BASE-T

  • IEEE 802.3ab
  • Cat 5e
  • provided more throughput for devices such as intra-building backbones, inter-switch links, server farms, and other wiring closet applications as well as connections for high-end workstations
  • Uses all 8 wires (4 pairs)
  • 4D-PAM5 line encoding is used on Category 5e, or better, UTP

1000BASE-SX and LX

  • IEEE 802.3 standard recommends that Gigabit Ethernet over fiber be the preferred backbone technology
  • 1000BASE-X uses 8B/10B encoding
  • Gigabit Ethernet permits only a single repeater between two stations

10 Gigabit Ethernet

  • full-duplex protocol that uses only optic fiber as a transmission medium
  • IEEE 802.3ae was adapted to include 10 Gbps full-duplex transmission over fiber optic cable
  • can provide increased bandwidth needs that are interoperable with existing network infrastructure

10 Gigabit Ethernet Architecture

  • rely on exact bit timing to separate the data from the effects of noise on the physical layer
  • By using codes to represent the user data, transmission is made more efficient
  • most 10GbE products are in the form of modules, or line cards, for addition to high- end switches and routers
