  1. Types of Cables Chapter 3

  2. Coaxial Cable - Coax • Cost:Inexpensive • Installation/maintenance:easy to install • Maximum segment length:185 meters • Bandwidth: 10 Mbps • Bend radius: 360 degrees/ft • Connector type:BNC • Interference Rating: Good-higher than TP

  3. Coax make-up • Conducting core • Insulation (PVC, Teflon) • Braided shielding • Sheath

  4. Twisted-Pair Cable • Two or more pairs of insulated strands of copper wire twisted around one another. • The twisting improves resistance to interference. More twists-better • Number of bundles wires ranges from 1-100 pairs

  5. Unshielded Twisted Pair • Also called 10BaseT • Maximum segment length:100 meters • Highly prone to crosstalk – the influence of signals traveling on one wire over another. • Uses RJ-45 connectors (telephone connector is RJ-11)

  6. Unshielded Twisted Pair

  7. UTP Categories • Category 1:standard telephone wire • Category 2:Up 4 Mbps with four pairs • Category 3:Up to 10 Mbps with 4 pairs • Category 4:Up to 16 Mbps with 4 pairs • Category 5:Up to 100Mbps with 4 pairs

  8. UTP/STP • Maximum cable length: 100 meters • Bandwidth: 10 – 100 Mbps • Bend radius: no limitations • Installation/maintenance: Easy to install • Cost: Least expensive of all options • Connector type: RJ45 • Interference rating: Low-most susceptible of all electrical cable types

  9. Fiber-Optic Cable • Data travels as pulses of light • Immune to interference • Highly secure • Most are two strand-

  10. Fiber-Optic • Maximum segment length:2-100 Kilos • Bandwidth: 100 Mbps-1 Gbps • Bend radius: 30 degrees/foot • Installation/Maintenance:Difficult • Cost: Most expensive of all options • Connector type:ST, SC, MIC, SMA • Interference rating: None

  11. Wireless Networking • Can create a hybrid network with traditional cabling and wireless. • Need a NIC that attaches to an antenna • Need an access point device (hub) to serve as an antenna • This devices is actually wired using traditional cabling to the network.

  12. Types of Wireless Transmission • Radio: 10 KHz to 1 GHz • Microwave: 1 GHz to 500 GHz • Infrared: 500 GHz to 1 THz
