HOW TO MAKE UTP CAT-5/5e CABLE LAB 1 – straight-through and cross over cable
RECALL: A straight cable is used to connect a computer to a: – switch – Hub – router – (different devices) A cross cable is used to connect: – Computer to Computer (with ONLY the UTP cable). – Network device to network device. For example: router to router, switch to switch – (same devices)
EQUIPMENT: 1.CABLE- CAT5/5e: – Referred as Ethernet cable – consists of four twisted pairs of copper wire terminated by a RJ-45 connector. – Has maximum length of 100m.
EQUIPMENT: RJ-45 connector – Short for Registered Jack-45, – is a 8-pinconnection
EQUIPMENT: Crimping Tools – is a tool designed to crimp or connect a connector to the end of a cable.
EQUIPMENT: Wire stripper – A tool designed to remove the protective covering off of a cable to expose the inner wires. – different wires come in different shapes, there are dozens of different wire strippers available. – strips a cable by placing the cable in-between the blade and one of the ridges and then spun around the cable until the jacket can be pulled off
EQUIPMENT: Cable tester – Use a network cable tester (also known as a patch cable tester) with the remote to test the continuity of individual cable pairs. – In auto mode, the test sequences run automatically
How to Identify an RJ-45 Straight-Through Cable Hold the cables side-by-side with the tab at the back. A straight-through cable wires are in the same sequence at both ends of the cable.

Hold the cables side-by-side with the tab at the back. The first (far left) colored wire (pin 1) at one end of the cable is the third colored wire (pin 3) at the other end of the cable. The second colored wire (pin 2) at one end of the cable is the sixth colored wire (pin 6) at the other end of the cable. How to Identify an RJ-45 Crossover Cable

STEP: Step 1 Use the wire stripper to cut the outer jacket of the wire about 1 inch to 1.5 inches from the end of the cable. When cutting the cable jacket, make sure that you do not damage the wires in the jacket. Step 2 Arrange the wires in the order that you want to install them into the RJ45 connector. The order of the wires is dependant on what type of connection you are making: crossover, rollover, or straight-through. Step 3 After arranging the wires in the correct order, cut them back so there is about 1/2 inch available to install in the connector. Step 4 Push the cable into the connector so that the jacket is past the plastic wedge at the rear of the connector and the wires are at the end of the connector underneath the gold crimping pins. Make sure each wire goes into the appropriate location. Step 5 Use your crimping tool to crimp the cable. Check your connection by tugging slightly on the cable. Recrimp as necessary. When you use the crimping tool, the plastic wedge is pressed into the cable jacket to hold the cable in place and the crimping pins are pushed down into the wires in the connector channels.
