  1. Matakuliah : H0451/Praktikum Jaringan Komputer Tahun : 2006 Versi : 1/0 Pertemuan 01Kabel

  2. Learning Outcomes Pada akhir pertemuan ini, diharapkan mahasiswa akan mampu : • Membuat kabel untuk jaringan komputer

  3. Outline Materi • Macam Kabel • Kabel UTP

  4. Cables Twisted Pair • The type depends on: • no. of pairs • no. of twists per unit length • gauge of the wire • type of insulation • Shielded Twisted Pair (STP): • expensive • higher data rate • easy to work with

  5. Cables • Un-shielded Twisted Pair (UTP): • low cost • lower data rate • limited length • easy installation • flexible configuration (when star wired) • supports many LANs and voice communication in the same cable type • easy fault isolation

  6. Cables • UTP Categories: • Category 3 • Up to 16 Mbps • used for 10baseT Ethernet & 4 Mbps Token Ring • Category 4 • Up to 20 Mbps • used for 16 Mbps Token Ring • Category 5 • Up to 100 Mbps • 100baseT Ethernet

  7. Media Other LAN Media • Infrared • modulated infrared signals passed through open space • Laser beam • modulated laser beams passed through open space • Microwave • high frequency radio waves passed by line of sight transceivers • Radio • earlier low speeds (9.6 - 230 kbps) - now 2-10 Mbps • used for mobile LAN stations when cabling is not possible

  8. Connectors • UTP: • RJ-11 (6 pins) • RJ-45 (8 pins) • pin-outs will differ according to LAN type • Thin Coaxial(10base2): • BNC (BayoNet Connector) • Terminator 50 • Thick Ethernet (10base5) • Transceiver • Attachment Unit Interface(AUI) < 50

  9. Interfaces • AUI – Attachment Unit Interface Medium independent attachment for 10 Mbps media systems • MAU – Medium Attachment Unit • MDI – Medium Dependent Interface • MII – Medium Independent Interface • GMII – Gigabit Medium Independent Interface • TBI – Gigabit Ten-Bit Interface To accommodate 8B/10B signal encoding in Gigabit Ethernet if 1000 BASE X is used • GBIC – Gigabit Interface Converter Hot swappable Media signaling components are contained

  10. Baseband Cable Types • UTP – 10 BASE T • Voice grade cabling • RJ-45 jack used • 100m maximum • 300mV signal squelch level (to eliminate cross talk signals) • but after 100m, due to attenuation, data signals also will go below this • 100  impedance (in some implementations 120 )

  11. Baseband Cable Types • 100 BASE T • unshielded or shielded (for Token Ring) twisted pair • 100m, 100, RJ-45 jack • 40 pin MII connector also may be used with an external transceiver (not commonly used) • data is scrambled to eliminate electro-magnetic effects

  12. Baseband Cable Types • 100 BASE FX • 40 pin MII may be used • if transceiver is built-in, fibre optic can be directly connected • Non-Return-to-Zero, Invert-on-Ones (NRZI) encoding is used • Peek optical transmission power is 200-400 W for 62.5/125 m fibre • No data scrambling needed • Two strands of multi-mode fibre optics are used for Tx and Rx

  13. Baseband Cable Types • 1000 BASE T • Gigabit Ethernet twisted pair • UTP all 4 pairs are used – requires CAT-5 or higher quality cables • Each pair has Tx and Rx wires (total of four Tx and four Rx wires in a cable) • hence total of 8bit at a time • 125 Mbaud achieves 1000 Mbps • A combination of signaling and encoding is used to achieve the speed • Digital Signal Processing (DSP) is used to handle cross talk • echo cancellation • near end cross talk (NEXT) cancellation • far end cross talk (FEXT) cancellation • signal equalization for distortion compensation

  14. Baseband Cable Types • 1000 BASE X • Gigabit Ethernet for fibre optic • SX – Short Wave Length • Most widely used • Less expensive • Short distance • Inside buildings • LX – Long Wave Length • 500 m • long haul version – 10 km • extended reach version – 70-100 km • CX – Short Copper Jumper • 25 m maximum • used for linking equipment in computer rooms, racks etc.
