Utp & fiber 1

  1. 1. Internet & Network Introduction UTP & Fiber CablingUTP & Fiber Cabling
  2. 2. Internet & Network Introduction UTP & Fiber CablingStructured Cabling Infrastructure • Mounted and permanent • Components: Information Outlet with Face Plate Patch Panel UTP Cable Patch Cord
  3. 3. Internet & Network Introduction UTP & Fiber CablingI/O & Faceplates• Faceplate mounts on or in wall or in raceway• Single or Dual Information Outlet (I/O)• Provide network connectivity to the Hosts through a Patch Cord
  4. 4. Internet & Network Introduction UTP & Fiber CablingPatch Panel• Termination punchdown in back• Patch cord plugin in front
  5. 5. Internet & Network Introduction UTP & Fiber CablingPatch Cord & UTP Connectors
  6. 6. Internet & Network Introduction UTP & Fiber CablingColor codes• Data Tx: 1 & 2• Data Rx: 3 & 6• Crossover 1 3 2 6• PoE +VDC: 4 & 5• PoE -VDC: 7 & 8
  7. 7. Internet & Network Introduction UTP & Fiber CablingCutting, Striping & Crimping Tools• Make your own patch cords• Cuts and strips pairs• RJ45 end crimped onto ends of wire
  8. 8. Internet & Network Introduction UTP & Fiber CablingPunching Tool• Terminates wires to back of patch panels and in Information Outlets
  9. 9. Internet & Network Introduction UTP & Fiber CablingMaking Cables
  10. 10. Internet & Network Introduction UTP & Fiber CablingMaking Cables (cont.)- Function of RJ45 plug New (not yet crimpled) connector Crimpled (without cable) connector Place for wires Place for cable jacket Function of RJ45 plug Contacts cut throughContacts insulation of each wire Triangle locks itself Triangle shaped piece of plastic to make a good electrical inside the place connection for the cable jacket to fasten the cable in
  11. 11. Internet & Network Introduction UTP & Fiber CablingMaking Cables (cont.)- Step 1 Strip about 1” (25mm) of the jacket off Don’t forget to put the boots on the cable first of all, if you are using them
  12. 12. Internet & Network Introduction UTP & Fiber CablingMaking Cables (cont.)- Step 2 Untwist and reorganize the wires to reflect Cut the wires to have ½” to ¾” one of the T568 standards (12 to 18mm) from the jacket edge Place the RJ45 plug on the cable. Be sure to keep the order of the wires!
  13. 13. Internet & Network Introduction UTP & Fiber CablingMaking Cables (cont.)- Step 3 Gently push the plug onto wires. Make sure, that all the wires are on the end of the plug and the jacket is inside the plug’s space for the jacket. Also look at the wires if they are still in the correct order.
  14. 14. Internet & Network Introduction UTP & Fiber Cabling Making Cables (cont.) - Step 4 Plastic triangle fastens the jacket Contacts are gnawed into the wires Push the cable end with the plug into the crimpling tool (usually you can hear gentle click sound) and crimp it hard enough to make good connection.Repeat the same steps on the opposite side of the cable, and then test the cable in the cable tester.
  15. 15. Internet & Network Introduction UTP & Fiber CablingWire Testing Equipment• Test wire for correct termination of 8 wires• Test for speed capabilities
  16. 16. Internet & Network Introduction UTP & Fiber CablingCabling Rules• Try to avoid running cables parallel to power cables.• Do not bend cables to less than four times the diameter of the cable.• If you bundle a group of cables together with cable ties (zip ties), do not over-cinch them. You should be able to turn the tie with fingers.• Keep cables away from devices which can introduce noise into them. Heres a short list: copy machines, electric heaters, speakers, printers, TV sets, fluorescent lights, copiers, welding machines, microwave ovens, telephones, fans, elevators, motors, electric ovens, dryers, washing machines, and shop equipment.• Avoid stretching UTP cables (tension when pulling cables should not exceed 25 LBS).• Do not run UTP cable outside of a building. It presents a very dangerous lightning hazard!• Do not use a stapler to secure UTP cables. Use telephone wire/RJ6 coaxial wire hangers which are available at most hardware stores.
  17. 17. Internet & Network Introduction UTP & Fiber CablingFiber Optic Cabling Infrastructure• Components: Fiber Cable Fiber Pigtail Fiber Connectors LIU/Fiber Patch Panel Coupler Fiber Patch Cord
  18. 18. Internet & Network Introduction UTP & Fiber CablingFiber Optic Connectors• Terminates the fibers• Connects to other fibers or transmission equipment ST Multimode Connector SC Multimode Connector LC Multimode Connector
  19. 19. Internet & Network Introduction UTP & Fiber CablingFiber Patch Cords & Pigtails• Ends are typically either SC or ST• Pigtails have connectors on only one side and Patch Cords have it on both sides.• Pigtails are spliced to the fiber to terminate the fiber Pigtail ST Multimode• Patch Cord connects switches to the Fiber cable Pigtail SC Singlemode Pigtail LC Multimode Singlemode Fiber patch cord SC - LC
