1) What is Cable Crimping
Cable crimping means to create an cable via crimping tools. There are many
types of cables which are use in Ethernet connection. Their cables are known as RJ45.RJ11,
etc.
The RJ45 cable is a standard cable which has four twisted pairs of colors. It is easy
to crimp a RJ45 cable and make it into a straight cable or cross the cable as required. To make a
straight cable, the ends must be crimped in the same way at each end. When making a crossover
cable, some wires of certain colors have to be reversed. Learning how to crimp a RJ45 cable and
making straight and cross cables prove to be useful as different types of wires of varied lengths are
required to build a network.

1) Types of Cable
You should know that not all Ethernet cabling is the same. If you go to a
store you may find a variety of “categories” of cabling. These categories tell you
the quality of the cabling. The quality determines, essentially, how much the
cable can handle. Here are the categories that you need to know:
Cat 3 – used for voice cabling and 10Mb Ethernet
Cat 5 – used for 10/100Mb Ethernet and works for voice as well
Cat 5E – Enhanced Cat 5 cabling that helps to prevent cross-talk, works for
10/100Mb and 1000Mb (or Gigabit Ethernet)
Cat 6 – Like Cat 5E but with larger gauge wires, works for 10/100/1000Mb. This
cable is better than Cat 5e for Gigabit Ethernet.
Cat 7 – Also called Class F, this is fully-shielded cabling and supports up to 600
MHz. This is a relatively new type of cabling and isn’t used much.
Most companies today are still using and even installing Category 5e as it
works for the 100Mb Fast-Ethernet in use on almost every desktop PC. Plus, it is
economicalcompared to the higher categories of cabling. If you go to a
computer store and buy an Ethernet cable, 99% of the time it will be a Cat 5e
cable.
Category Data-Rate Signal Frequency
Cat 5 100 Mbps 100MHz
Cat 5E 100 Mbps – 1 Gbps 100MHz
Cat 6 1 Gbps – 10 Gbps 250MHz
Cat 7 1 Gbps – 10 Gbps 500MHz

Ethernet cable contain mainly 4 type of wire.

There are sub color also of 4 type of cable. That are as follows:
i. Brown
ii. White-Brown
iii. Green
iv. White-Green
v. Blue
vi. White-Blue
vii. Orange
viii. White-Orange

Here,the cables which are inserted into pin 1 & 2 will do the work for data transmission
and pin 3 & 6 will receive data.

2) How to wire
Begin by stripping the outer covering from the end of the cable. Remove about an
inch of covering.
Eventually you'll have to cut down the amount of exposed cable, but the process of
installing the RJ-45 connector will be easier if you have plenty of exposed cable to work with.
Once you remove the outer cover, you'll see that some of the pairs of wire are twisted
together (hence the name twisted-pair cable).
Untwist these wires. Once all the wires have been separated,pull them backward,as
shown below, so you can cut off the exposed plastic core, as shown below.
Remove as much of this core as you can. Be carefulnot to accidentally cut the wires in
the process.
Now that the core has been removed, your next task is to straighten the wires that were
previously twisted.
Once you've straightened the wires, your next task is to arrange them in the order they'll
be placed into the RJ-45 connector. Working from left to right, the order of the wires is:

You'll want to make the cut so that the ends of the wires line up evenly.
When the cable is finally cut to the correct length, you should check a few things
before crimping the cable.
Make sure you see copper in eachwire slot
You should also verify that the wires are still in the correct order.

Assuming the wires are in order, you can go ahead and crimp the cable. When you've
finished crimping both cable ends, you can use a cable tester to verify that the ends were
installed correctly.
At last Cable is Ready to Use:
