Ethernet cable types

There are 3 types of Cables.

1. Straight Through Cables

If we want to connect two different types of device then we can use straight-through cables.
For example:
> Connecting a router to a hub
> Connecting a computer to a switch/router
> Connecting a modem to a router

 

2. Crossover Cables

If we want to connect two same types of device then we can use crossover cables.
For example:
> Connecting a computer to a computer
> Connecting a router to a router
> Connecting a switch to a switch
> Connecting a hub to a hub

 

3. Rollover Cables

This cables is used to connect computer to router’s console port.It is also called as console cable or yost cable.

Ethernet Cable Type

In computer networks, Cat-5, Cat-5e, and Cat-6 cables are mostly used. UTP cables are connected by RJ45 connectors.
Cable Type and  Speed
CAT 3 16Mbps
CAT 5 100Mbps 1000Mbps (4 pairs)
CAT 5E 1000Mbps
CAT 6 Up to 400MHz for super-fast broadband applications
Cat 7 cabling is also known as Class F.

We will use  “Cat 6” cables for now.

6. Now your LAN cable is ready you may now test the cable sing LAN tester.

Note :
T568A and T568B are the two different colour codes used for pairing cable.
T568B is mostly used one.

Crimping a Straight through cable :

Arrange all wire in the below manner and cut the edge ,be careful in doing so.Both end of cable must have same sequence of colored wire,please refer the below image.

Both End of wire arrangement in cable is same.

Now insert the cable into jack and then crimp the cable using crimping tool
So now we crimped one side of the cable.so we can repeat the step for another side of cable.

Crimping a Crossover cable :

Arrange the cable as shown in below image .

Both End of wire arrangement in cable is different.

Crimping LAN Cables crossover-cable

Now insert the cable into jack and then crimp the cable using crimping tool
So now we crimped one side of the cable.so we can repeat the step for another side of cable.

Now cable is ready to use,You can test your cable using ” LAN Cable Tester” too.

Please Note :
With Auto-MDIX (Medium Dependant Interface Crossover) in PC’s/Motherboard straight through cable or a crossover cable can be used for PC-PC connection.
