2 Task Sheet Unit OBJECTIVE Understand the steps to make and test a CAT5 Straight Through cable. You will be covering the following Student Learning Outcomes (SLO) Assemble a straight through cable. Test a network cable for physical faults Explain the difference between a cross cover and straight through cable EQUIPMENT REQUIREMENTS Pen, Pencil, Laptop or Computer, Paper SAFETY REQUIREMENTS N/A TASK INTRODUCTION Category 5 or CAT5 are used in structured cabling for computer networks such as Ethernet. In this task you are going to write the different steps required and tools used to build a CAT5 cable.. Page 1 of 6

3 Teacher Guidelines: Work Plan Where students response may vary please use your professional judgement. No. Work Steps Step Completion & Values Remarks 1 What does this image shows? After this step what happens to the cable? The cable is cut. After this step the cable will be to the desired length required by the user. Cut the cable to the length needed. Why do you do this step to the cable? Removing the jacket is to expose the wires in the cable. Strip back the cable jacket approximately 3cm 3 1 1) What is done in step 1? Un-twist each of the 4 pairs and straighten each wire as much as possible between the fingers. ) How does the cable look in step after completing step? 1 The wire looks strightened after separated from each of the twist..

4 4 Use the 568-B wiring scheme on both ends for a standard patch cable. Fill up the blanks according to the pin number the color codes for 568-B cable. The first one is done for you. 568-B wiring scheme Pin # Wire Color 1 White / Orange Orange 3 White/Green 4 Blue 5 White/Blue 6 Green 7 White/Brown 8 Brown 5 Why do we have to do this step while cable making? Wires are brought together closely for getting ready to cut desired length and insert into the connector. 6 Bring all of the wires together as closely as possible. Do you see the wires are not straight at the end? Hold the grouped (and sorted) wires together tightly between the thumb, and the forefinger. 1 Cut all of the wires at a perfect 90 degree angle from the cable, approx 0.5cm from the end of the cable jacket. What is done in step 1? Wire is getting cut to desired length. What is the name of the tool? Crimp tool is used for cutting the wire. How the cable appear in Step after completing step 1 process? The wires are arranged in the correct order of the color scheme. Page 3 of 6

5 7 Decsribe what s done to the cable in this step. With the connector pins facing up, carefully the wires are inserted into the connector. 8 Is this cable connected rightly to the connector? Is yes or no explain. Observe the tip of the connector to confirm that all the wires are fully inserted. Yes, the cable is rightly connected to the connector. We can see that the jacket is inside the connector and the pins are in same length, inserted until the end of the connector. 9 Decsribe what s done to the cable in this step. Place the connector into the crimp tool, and squeeze hard so that the handle reaches its full swing. 10 Name the device shown in this step. What is the use of this device? [G This is a cable tester. A cable tester to check for continuity, opens and shorts. What are the differences between a straight through cable and cross over cable? Give atleast two examples of devices connected using each type of cable. Straight through cables connects diiferent networking components together. e.g computers to routers, modems and other pheripherals. Cross over connects devices with the same interface together. e.g switches to switches, peer to peer, hub to hub, access point to access point Page 4 of 6

6 A Check of Dimension and Function No. Points Student Teacher 1. Can identify the work of crimping tool.. Can understand the need of exposing the cable wires, unpairing and straightening the wire. 3. Can identify all the 8 pins wire colors 4. Can explain the need to bring the uneven ends wires together, cut and arrange the wires by the color order. 5. Can explain the wires put in the connector. 6. Can explain the use of wire crimping. 7. Can explain the need for a cable tester and differentiate straight through and cross over cables Maximum Achievable Points 7 Summarization of Actual Points B Visual Checks No. Inspections Explanation Student 1. Cable wires color codes are in the right order of the pin number.. The purpose of use of crimping tool and connector is clear. 3. The purpose of the cable testing is clear. Maximum Achievable Points 3 Summarization of Actual Points Teacher A X 70 % + X 70 % A + B + = X 30 % X 30 % B Page 5 of 6

7 Marking Rubrics A Check of Dimension and Function No. Points Can identify the work of crimping tool. Can understand the need of exposing the cable wires, unpairing and straightening the wire. 3 Can identify all the 8 pins wire colors 4 Can explain the need to bring the uneven ends wires together, cut and arrange the wires by the color order. 5 Can explain the wires put in the connector. 6 Can explain the use of wire crimping. 7 Can explain the need for a cable tester and differentiate different cable types.. B Visual Checks Page 6 of 6 Student can identify the woking of crimping tool. Student can understand the preparation of cable wire for crimping. Student can understand the wire color order. Student can understand the need for wire length Student can understand the correct way to push in the connector. Student understand the need of crimping in the right position. Student understand the different cable types and the need of cable testing to test its working. No. Points Cable wires color codes are in the right order of the pin number. The purpose of use of crimping tool and connector is clear. 3 The purpose of the cable testing and cable types are clear. Student rightly had written the color of the wire. Student rightly had written the use of crimping tool and how connector is used. Student had written the use of a tester and differentiated on cable types and cable making.
