This presentation covers the topic Connecting media tells us about what cables and connectors do we need in in establishing connections in our network.A practical source is also displayed here covering what tools are used in making up of a cable.how Cabling and clamping is done. This ppt was used byu me to deliver inbound training for my office staff.

1. L E A R N T O E S TA B L I S H C O N N E C T I O N S
CONNECTING MEDIA

2. OVERVIEW
• What cable types are available?
• How do cables work?
• How are cables used in networking?
• How are connections made?

3. LEARNING OBJECTIVES
• List common cable types used in networking
• Describe how UTP cables are made
• Explain how UTP cables are used in Ethernet
networks
• Demonstrate the ability to make a working patch
cable
• Name the two wiring standards used for wired
Ethernet networks and their uses

4. COMMON NETWORK CABLE TYPES
Coaxial cable
Unshielded
twisted pair
Fiber optic

5. UTP CHARACTERISTICS
• Unshielded
• Twisted (why?) pairs of insulated conductors
• Covered by
insulating sheath

6. UTP CATEGORIES

7. CAT-5E CABLE
• 1000Mbps data capacity
• For runs of up to 90 meters
• Solid core cable ideal for structural installations (PVC
or Plenum)
• Stranded cable ideal for patch cables
• Terminated with RJ-45 connectors

8. MAKING CONNECTIONS - TOOLS
• Cat5e cable
• RJ45 connectors
• Cable stripper
• Scissors
• Crimping tool

9. MAKING CONNECTIONS - STEPS
1. Strip cable end
2. Untwist wire ends
3. Arrange wires
4. Trim wires to size
5. Attach connector
6. Check
7. Crimp
8. Test

10. STEP 1 – STRIP CABLE END
• Strip 1 – 1½” of insulating sheath
• Avoid cutting into conductor insulation

11. STEP 2 – UNTWIST WIRE ENDS
• Sort wires by insulation colors

12. STEP 3 – ARRANGE WIRES
• TIA/EIA 568A: GW-G OW-Bl BlW-O BrW-Br
• TIA/EIA 568B: OW-O GW-Bl BlW-G BrW-Br

13. STEP 4 – TRIM WIRES TO SIZE
• Trim all wires evenly
• Leave about ½” of wires exposed

14. STEP 5 – ATTACH CONNECTOR
• Maintain wire order, left-to-right, with RJ45 tab
facing downward.

15. STEP 6 - CHECK
• Do all wires extend to end?
• Is sheath well inside connector?

16. STEP 7 - CRIMP
• Squeeze firmly to crimp connecter
onto cable end (8P)

17. STEP 8 – TEST
• Does the cable work?

18. COLOUR CODING
LETS NOW IDENTIFY IT !!

19. COLOR CODES
Data Tx: 1 & 2
Data Rx: 3 & 6
Crossover
1  3
2  6
PoE +VDC: 4 & 5
PoE -VDC: 7 & 8

20. IMPLEMENTATION OF COLOR CODE

21. IMPLEMENTATION OF COLOR CODE

22. WHICH CABLE ?WHERE ?
Straight through
• Switch-To-PC.
• Router-To-Switch.
Cross over
• Switch-To-Switch.
• Router-To-Router.
• Router-To-PC.

23. STRUCTURED CABLING
LET’S GET SET TO WORK !!!

24. STRUCTURED CABLING
INFRASTRUCTURE
Mounted and permanent
Allows patching
Comfort that infrastructure is OK
Components:
Information Outlet with Face Plate
Patch Panel
UTP Cable
Patch Cord

25. I/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.

26. PATCH PANEL
Termination punch down in back.
Patch cord plugin in front.

27. PATCH CORD & UTP CONNECTORS

28. CABLING RULES
SOME DO’S AND DON’T’S

29. CABLING RULES
• Avoid running cables parallel to power cables.
• Bending of cables
• Do not over-cinch.
• Avoid stretching UTP cables
• Do not run UTP cable outside of a building.
• Do not use a stapler to secure UTP cables.
• Use telephone wire/RJ6 coaxial wire hangers
which are available at most hardware stores.
