TP is a 8 wire cable in four pair
Colour of cables are :-
II. White Green
IV. White Orange
VI. White Blue
VIII. White Brown
The White Colour means that the cable consist of two colour lining on it eg white Green it consist one line of white colour and second on colour Green on it
We Can create Three type of cables by using Pair
1. Straight Cable
2. Cross Cable
3. Roll-over Cable
The Straight and cross Cable are used for communication .And Roll-over cable
used for configuration.
We use straight cable for communication between two different devices and Also for internet access on Device.
These three of cable are fixed on RJ45 ,
We Use Two Standard For Cabling:
1. 568A Standard
2. 568B Standard
“When 568A Cabling On Both end of cable then this cable is Straight cable”
“When 568A Cabling On one end and 568B on second end of cable then this cable is Cross cable”
“When 568A Cabling On Both end but on second end it is opposite means A865
cable then this cable is Straight cable (on One end 12345678 on second end
2. Connector (RJ45).
3. Clumping Tool.
4. LAN Tester.
