Roll of Cat5 FTP CCA Ethernet Cable

Used in conjunction RJ45 connectors & a crimping tool for:

building Local Area Networks (LANs) for connecting computers, printers etc into a network
connecting the ethernet port on a satellite receiver to the internet
connecting IP security cameras back to a router

Note see 'Wiring Video' tab for detailed guide

NOTES ON Cable & Connectros

The RJ stands for 'Registered Jack'
The RJ11 comes with 4 pin slots
- Only the 2 middle pins are needed
- It is used for dial up internet or voice but not broadband.
- it is used with telephone cables
If the RJ connector has copper pins in all 4 slots
- it is actually an RJ14 but can be used as if it was an RJ11
The other commonly used RJ plug is the RJ45
- it is used with LAN networks, ethernet ports etc
- it has 8 pins
- It is used with CAT5 Cable

Below is documented the correct wiring format for a CAT5 Cable and detailed instruction for making a CAT5 Cable.

WIRING DIAGRAMS FOR A CAT5 CABLE

Cat5 568-B Type Wiring Diagram
Notes

The diagram above is called a CAT5 Type B wiring method which is the one that is almost exclusively used in industry.

Equipment needed

Using a crimping tool remove the outer protective sleeve leaving around 25mm of cable exposed
Next untwist each of the pairs of cables
Line up the wires in accordance with the wiring diagram above
Again using the crimping tool cut the cable leaving about 12-15mm of cable exposed.
Push the cables into the RJ45 Plug
Use the crimping tool to crimp the RJ45 Connector on the the cable
Cut the CAT5 cable to the required lenght
Repeat the process to put a connector on the far end

There is an alternate wiring convention for CAT5 cables called 568-A. See diagram below:

Cat5 568-A Type Wiring Diagram

The most common use of this convention would be use a Type A & and a Type B connector to make a cross over cable.

The most commonly used cat5 cable is UTP (Unshielded Twisted Pair) cable. This is suitable for homes and offices
A more expensive option is to use FTP (Foil shielded Twisted Pair) cable
Which gives greater interference protection when running next to power cables
