  3. Media on PC • Ethernet • Modem • PC Card (WLAN) • DVB

  4. Ethernet - Architecture

  5. Ethernet • [ ] [ ] [ ] • Contoh 100BaseT • Kecepatan : 10, 100, 1000 • Type : Base/Broad • Model : 5, 2, T, Fx,

  6. Ethernet – IEEE 802.3 • 10Base5 – Thick wire coaxial • 10Base2 – thin wire coaxial / cheaper net • 10BaseT – Twisted Pair • 10BaseF – Fiber Optics 100BaseT – Fast Ethernet

  7. Ethernet – 10Base5

  8. Ethernet – 10Base2

  9. Ethernet – 10BaseT

  10. NIC Connector type • Coaxial Cable • Bayonet Nut Connector (BNC) • Twisted Pair Cable • RJ-45 (8 wire) • Fiber Optics • SMA connectors

  11. Apa sih NIC? • An Ethernet 10/100 PCI

  12. BNC COMBO

  13. PENGKABELAN BNC

  14. Dummy load Pengkabelan

  15. Pasang LAN card ke PC

  16. Modem • Allows modems of different vendors to operate together • Define How modems operate: • Modulation techniques • Data compression technique • Error detection strategy

  17. Modem – Analog vs Digital • Analog • Infinite number of levels • Conform to voice pattern • Times from highest to lowest and back to the highest point in one second is the frequency • Can be transmitted over long distance • Digital • Only two levels (high and low) • Conforms to how computers operate • Cannot transmitted over long distance

  18. Modem - Connection

  19. Modem – Internal/External

  20. PC Card (WLAN) - 1

  21. PC Card (WLAN) - 2

  22. PC Card (WLAN) – Indoor Antena

  23. PC Card – WLAN (802.11) • Bypassing last mile

  24. DVB – DVB/IP Tech • The Digital Video Broadcast over Internet Protocol (DVB/IP) system is functionally an IP-over-Ethernet simplex satellite service that incorporates frame-relay type traffic management. At its core, DVB is a modem-on-a-chip, plus an intelligent multiplexer. The antenna is typically a CATV dish, 2.4 - 3.8 meters in diameter (for C-band), or 0.6 -1.8 meters (for Ku-band).

  25. DVB – DVB/IP Routing

  26. DVB - Adaptability

  27. DVB – DVB Card

  28. Media • Wired • Twisted Pair – UTP • Coaxial • Fiber • Wireless • Microwave • Satellite

  29. Twisted Pair • Two wired wrapped in a twisted fashion • Designed to reduce cross-talk due inductance • Still subject to interference from stray signal • Primarily used for local loop connections and LANs • Comparatively narrow bandwidth

  30. UTP – Unshielded Twisted Pair • Pair 1 • White/blue • Blue • Pair 2 • White/Orange • Orange • Pair 3 • White/Green • Green • Pair 4 • White/Brown • Brown • RJ45 Connector

  31. Kabel Twisted-pair Rj-45 connector

  32. UTP – Straight Cable Wo/O Wg/B Wb/G Wbr/Br

  33. UTP – Cross Cable Wg/G Wo/B Wb/O Wbr/Br

  34. Aturan Pengkabelan (1)

  35. Aturan Pengkabelan (2)

  36. UTP - Category

  37. Coaxial • Center lead conducts the signal • Protected by insulation and braded wire • Used mostly for television and connections to antenna • Larger Bandwidth but large in size

  38. Jenis Medium Panjang max tanpa cacat Coaxial cable RG-58 (10BASE2) 10 Mbit/s BASEBAND

  39. Fiber Optical • Signal transmitted by photos rather than electrons • Dramatically higher bandwidth • Used mostly for backbone communication connections, very high speed LANs and fast network connections

  40. SC ST FO Connector

  41. Microwave – Antenna (1) • Omni • 2.4GHz 8dBi

  42. Microwave – Antenna (2) • Sectoral • 14dBi 180deg
