Of network cable which is used for wired networks (a Ethernet cable- An Ethernet cable is a very popular type work type which connects devices to the Internet or other networks using cables). They are used to connect devices located on local area networks (LANs), such as routers, PCs and switches.



Components for making Ethernet cable

👉RJ-45 Connector

The eight-pin RJ45 connector is a standardised interface which often connects a computer to a local area network (LAN). This type of connector was originally developed for telephone communications but is now used in a range of applications. The abbreviation, RJ45, stands for Registered Jack-45. 



👉Twisted-pair cables

The pair of twisted is the simplest transmission medium. it consists of one or more pairs of electrical son arranged spiral. This type of support is suitable for transmission both analog and digital.
The twisted pairs may be shielded, metal sheath surrounding completely metallic pairs or unshielded. They can also be “unscreened”. In this case, a metal tape around the son.
Numerous debates take place about the advantages and disadvantages of the shielding of these cables. We can say, simplifying, a shielded cable should be better able to immunize transported signals. The disadvantage of the shield is however that it requires the grounding of the whole equipment, since the physical support to the terminal. This requires that all land connection string is properly carried out and maintained. 

In other words, a shielded network must be very good, otherwise it may behave worse than an unshielded network, much cheaper.

A twisted pair consists of two copper wires about 1 mm thick.




👉Crimping tools 

Crimp tools are a varied collection of devices used to join materials or components by pressing them together and creating a seal or crimp. One of the most common uses of crimping tools is the attachment of connectors to the end of electrical cables.



To do these practical following steps should be done:



1. Strip the cable back 1 inch (25 mm) from the end. Insert the cable into the stripper section of the tool and squeeze it tight. Then, rotate the crimping tool around the cable in a smooth and even motion to create a clean cut. Keep the tool clamped and pull away towards the end of the wire to remove the sheathing.[1]
⦁ The stripping section is a round hole near the handle of the tool.
⦁ The sheathing should come off cleanly, leaving the wires exposed.








2.Untwist and straighten the wires inside of the cable. Inside of the cable you’ll see a bunch of smaller wires twisted together. Separate the twisted wires and straighten them out so they’re easier to sort into the right order.[2]
⦁ Cut off the small plastic wire separator or core so it’s out of the way.
⦁ Don’t cut off or remove any of the wires or you won’t be able to crimp them into the connector.






3.Arrange the wires into the right order. Use your fingers to put the wires in the correct order so they can be properly crimped. The proper sequence is as follows from left to right: Orange/White, Orange, Green/White, Blue, Blue/White, Green, Brown/White, Brown.[3]
⦁ There are 8 wires in total that need to be arranged in the right sequence.
⦁ Note that the wires labeled Orange/White or Brown/White indicate the small wires that have 2 colors.





4.Cut the wires into an even line 1⁄2 inch (13 mm) from sheathing. Hold the wires with your thumb and index finger to keep them in order. Then, use the cutting section of the crimping tool to cut them into an even line.[4]
⦁ The cutting section of the tool will resemble wire cutters.
⦁ The wires must be in an even line to be crimped into the RJ-45 connector properly. If you cut them in an uneven line, move further down the wires and cut them again.







5.Insert the wires into the RJ-45 connector. Hold the RJ-45 connector so the clip is on the underside and the small metal pins are facing up. Insert the cable into the connector so that each of the small wires fits into the small grooves in the connector.[5]
⦁ The sheathing of the cable should fit just inside of the connector so it’s past the base.
⦁ If any of the small wires bend or don’t fit into a groove correctly, take the cable out and straighten the wires with your fingers before trying again.
⦁ The wires must be inserted in the correct order and each wire must fit into a groove before you crimp the connector.







6.Stick the connector into the crimping part of the tool and squeeze twice. Insert the connector in the crimping section of the tool until it can’t fit any further. Squeeze the handles to crimp the connector and secure the wires. Release the handles, then squeeze the tool again to make sure all of the pins are pushed down.
⦁ The crimping tool pushes small pins in the grooves down onto the wires to hold and connect them to the RJ-45 connector.
