is very important thing in doing a network cable connections. Network Color coding are used to specify the kind of connection are you going to do or what devices are going to connect. There are three common Network connections that are using a color coding in order to connect those Hardware and Devices. These are the connections from PC to another PC, the connections from PC to HUB, And the connections from Router to any Devices. These three connections are using different types of color settings of a network cable according to its standard cable color settings of the devices that are going to connect.
In doing the Network Cable Color Coding you must have these Equipments:
• Cat5 Network Cable - These is a network wire cable with eight different colors inside the shield of the cable. It is used to connect those devices.
•
• RG45 - it is attached in the both ends of the network cable wire and it is the used to connect the two devices with both RG45 ports. Example, from PC to PC with both LAN Cards.
•
• Crimping tools - Used to Cut the cable wire and to compress the RJ45 so the Cat5 wire will attached to the RG45
•
• Local Area Network (LAN) Tester - It is used to test the network cable wire connectivity speed and in order you to know that your crimped cable wire is working

Uasge Of Networking Cable
LAN Pinouts (10baseT and 100baseT)
UTP by the way stands for Unshielded Twisted Pair. LAN cabling can be very confusing with the different types of possible connection. With the choice of colored cable available to-day there is no real excuse for not using a simple color coding scheme to rapidly differentiate between cable types (there is NOTHING more annoying than to get the wrong cable).
NOTE 1: You can get heat shrink color coded sleeves which you fit on each end of the cable beside the connector to indicate the wiring type and standard instead of using different colored cables.
NOTE 2: Almost all our wiring is now done to the 100baseT spec which you can use with 10baseT networks - but NOT the other way around.

The following table shows the normal color coding for category 5 cables (4 pair) based on the two standards supported by TIA/EIA
10base Straight Cable (PC to HUB/SWITCH)
Straight cables are used to connect PCs or other equipment to a HUB or Switch. If your connection is Pc to PC or HUB to HUB you MUST use a Crossed cable.
The following cable description is for the wiring of both ends (RJ45 Male connectors) with the 568A category 5 wiring colors.

NC means not connected.
We use BLUE CABLE for 10baseT straight cables.
10baseT Crossed cable (PC to PC or HUB to HUB)
Crossed cables are used to connect PCs to one other PC or to connect a HUB to a HUB. If your connection is PC to HUB you MUST use a Straight cable.
The following description shows the wiring at both ends (male RJ45 connectors) of the crossed cable.

100baseT Straight Cable (PC to HUB/SWITCH)
Straight cables are used to connect PCs or other equipment to a HUB or Switch. If your connection is Pc to PC or HUB to HUB you MUST use a Crossed cable.
