Each year 1.5 million shelter animals are euthanized (670,000 dogs and 860,000 cats). Source: ASPCA. The solution is not to shelter unwanted pets, but to SHUT DOWN THE PET MILLS. Anyone who wants a pet will just have to adapt a great pet from a shelter.

How to Make a Network Cable

Ethernet Cat 5 cable The steps below are general Ethernet Category 5 (commonly known as Cat 5) cable construction guidelines. For our example, we will be making a Category 5e patch cable, but the same general method will work for making any category of network cables.


1. Unroll the required length of network cable and add a little extra, just in case. If a boot is to be fitted, do so before stripping away the sleeve and ensure the boot faces the correct way.

Remove the outer jacket 2. Carefully remove the outer jacket of the cable, exposing about 1 1/4" (30 mm) of the twisted pairs. Be careful when stripping the jacket as to not nick or cut the internal wiring. After removing the outer case, you will notice 8 wires twisted in 4 pairs. Each pair will have one wire of a certain color and another wire that is white with a colored stripe matching its partner (this wire is called a tracer). Sometimes a rip cord (white thread) is also present.


Inspect wires for any cuts or scrapes 3. Inspect the newly revealed wires for any cuts or scrapes that expose the copper wire inside. If you have breached the protective sheath of any wire, you will need to cut the entire segment of wires off and start over at step one. Exposed copper wire will lead to cross-talk, poor performance or no connectivity at all. It is important that the jacket for all network cables remains intact.


Untwist the pairs so they lay flat 4. Untwist the pairs so they will lay flat between your fingers. The white piece of thread can be cut off even with the jacket and disposed (see Warnings). For easier handling, cut the wires so that they are 3/4" (19 mm) long from the base of the jacket.


Arrange the wires 5. Arrange the wires based on the wiring specifications you are following. There are two methods set by the TIA, 568A and 568B. Which one you use will depend on what is being connected. A straight-through cable is used to connect two different-layer devices (e.g. a hub and a PC). Two like devices normally require a cross-over cable. The difference between the two is that a straight-through cable has both ends wired identically, while a cross-over cable has one end wired 568A and the other end wired 568B. For our demonstration in the following steps, we will use 568B, but the instructions can easily be adapted to 568A.

568B - Put the wires in the following order, from left to right:

  • white orange
  • orange
  • white green
  • blue
  • white blue
  • green
  • white brown
  • brown

568A - from left to right: white/green, green, white/orange, blue, white/blue, orange, white/brown, brown. You can also use the mnemonic 1-2-3-6/3-6-1-2 to remember which wires are switched.
