Transmission and Signaling Basics

• Basic arbitration is embedded in standard chips
• Collision detection
• Backoff mechanism
• Retransmits
• Some Industrial Ethernets use special chips to
  alter this basic characteristic
• Wiring and topology choices can cause problems

3
Routing Addressing Enabling Equipment

• Hub connects together two or more computers to
  form one Ethernet segment
• broadcasts packets out to all devices
• low intelligence and cheap
• also known as a repeater, concentrator, bridge
• Switch capable of inspecting packets,
  determining the source and destination and
  greatly reducing traffic
• transmits packets only to intended devices
• prevents collisions from occurring
• Can be used to diagnose network performance

4
Ethernet Switch Basics

• Unmanaged Requires no intervention from the
  user or software configuration
• Also called Store and Forward or auto
  learning
• low intelligence and cheap
• Segments the network and prevents collisions
• Managed Can be setup by the user for
  intelligent inspection of packets and diagnostics
  of through traffic
• Can use rules to change packet pathways
• Abstracts addresses, creates redundancy, filters
  traffic
• Can be used to diagnose network

  45 to 1 10/100 Base T fiber connector

Sell.. .. if a long distance link is
required in a copper based Ethernet .. where
small footprint (25 mm) is required in the
cabinet .. if industrial environment requires
extended temperature

Prices in Euros and USD

• Remember..
• .. Singlemode fiber is much more expensive to
  buy and install dont give the converter away!
• .. MSC population option is stocked and
  standard, other variants may have a 2-3 week lead
  time
• .. An unmanaged switch can be used to accomplish
  the same task but customers may be specifying
  converters

Multimode Fiber

• A multimode fiber has a dimension that affords
  space for several modes in a core
• Multimode cables are available in two categories,
  these are graded index and step index

• Step index modes degrade or attenuate unevenly,
  resulting in lower bandwidth and distance
• Graded index refractive index reduces gradually
  from the cores centre towards the cladding.
  Overall effect keeps the pulse together

The most common dimension of multimode cable is a
62.5 µm core and 125 µm outer cladding (the cable
is then designated 62.5/125).
10
Singlemode Fiber

• A singlemode fiber has such a fine core that it
  only supports one mode, which means that the
  transmitted light pulse is not distorted when
  traveling through the cable

• Long distance lack of attenuation gives superior
  performance
• High Cost glass only, thin core is expensive to
  buy and install

The most common singlemode cable dimension is 9
µm core and 125 µm cladding (9/125)

Some Key Switch Management Functions

• Simple Network Management Protocol (SNMP) a set
  of protocols for managing network performance,
  finding and solving network problems, and
  planning for network growth
• Internet Group Management Protocol (IGMP)
  configures broadcast message behavior
• Virtual LAN (VLAN) a network of computers that
  behave as if they are connected to the same wire
  even though they may actually be physically
  located on different segments of a LAN
• Quality of Service (QoS) Allows prioritization
  of packets to occur to improve performance for
  key channels
• Spanning Tree Protocol (STP) algorithm to
  prevent wiring topology mistakes or create
  redundancy in a network
