About Ethernet Cables

• Common Ethernet cables that are used are either
  Cat 5 or Cat 6. Both are mediums that are used to
  transmit data over a network between various
  network devices and computers.
• Crossover cables can also be used to connect
  similar devices to each other, such as two
  computers or two routers for connecting multiple
  networks.

Wiring Color Schemes

• There are two different standards set for
  punching down the various color combination wires
  within the actual Ethernet cable. Several wires
  are used for transmitting as well as receiving
  data that is being sent over.
• If the color schemes do not match properly, there
  is a high chance that the data will not transmit,
  or will corrupt that information that is being
  sent through them.
• The wires must have their outer casing removed in
  order to be exposed, but it is important to not
  remove too much of the shelling because their
  could be crosstalk, or interference, between the
  cables if exposed.

Wiring Color Schemes (cont.)

• Either standard can be used for a basic straight
  through cable
• A cross between the two is used when making the
  previously mentioned crossover cables. This
  requires that one end of the cable is 568B, and
  one 568A

Putting it all Together

• It is important that all of the cables are
  untwisted before attempting to put them into the
  RJ-45 plug
• Using a crimping tool is best suited for
  attaching the cable and the plug.
• Make sure that an ample amount of wiring is cut
  when removing the desired amount from the spool
  to ensure that you are not short handed when
  using the cable.
