Lab Manual: Computer Networks Department of Information Technology Experiment - One Objective: Study of different types of Network cables and practically implement the crosswired cable and straight through cable using clamping tool. Straight Over: A straight through network cable acts as an extension enabling a device with a network interface card to be attached to a network. A common form of network media is the UTP Cat5 (Unshielded Twisted Pair Category 5) cable. The cables should have their sleeving trimmed back at each end by approximately 13mm in order to expose the wires for sorting. The wires should then be flattened out and sorted into the following order from left to right; White/Orange, Orange, White/Green, Blue, White/Blue, Green, White/Brown, Brown. At this point it is best to make sure that the wires are the same length and trim them as necessary. It’s a good idea to check the order of the wires before moving onto the next stage to make sure that orange and brown have not been mixed up as some white wires don’t have their markings coloured clearly. Once the wires are confirmed to be in the correct order then it is time to attach the RJ-45 connectors. This is a simple case of pushing the wires in as far as they will go and then using a crimping tool to secure them into place. Once one end is done simply repeat the process for the second end, after that be sure to test the cable with an appropriate device before using it in your network. RJ-45 connectors are the most common form of connectors used on UTP Cat5 cables. The RJ simply means Registered Jack and the 45 designation specifies the pin numbering scheme. The cable itself contains 4 twisted pairs of wires making a total of 8 wires. Roll Over: Crossover wired cables (commonly called crossover cables) are very much like StraightThrough cables with the exception that TX and RX lines are crossed (they are at opposite positions on either end of the cable. Using the 568-B standard as an example below you will see that Pin 1 on connector A goes to Pin 3 on connector B. Pin 2 on connector A goes to Pin 6 Prepared By: Mr. Imran Khan,Associate Profesor,OCT,Bhopal Page 3

Examples would be connecting a computer directly to another computer, connecting a switch directly to another switch, or connecting a router to a router.

Cable & RJ-45 Jack outlet installation Do not strip the insulation off of the individual paired wires. Just remove about 40mm of the jacket as shown below photo 1. The way the stripper tool works is the cable is inserted into the stripper and then the stripper is rotated a couple of times allowing the tools cutting blade to score the cable‘s outer jacket only.
