What is the difference between LAN cable and Cross cable?
Common Ethernet network cable are straight and crossover cable. This Ethernet network cable is made of 4 pair high performance cable that consists twisted pair conductors that used for data transmission. Both end of cable is called RJ45 connector.

he cable can be categorized as Cat 5, Cat 5e, Cat 6 UTP cable. Cat 5 UTP cable can support 10/100 Mbps Ethernet network, whereas Cat 5e and Cat 6 UTP cable can support Ethernet network running at 10/100/1000 Mbps. You might heard about Cat 3 UTP cable, it’s not popular anymore since it can only support 10 Mbps Ethernet network.

Straight and crossover cable can be Cat3, Cat 5, Cat 5e or Cat 6 UTP cable, the only difference is each type will have different wire arrangement in the cable for serving different purposes.

You usually use straight cable to connect different type of devices. This type of cable will be used most of the time and can be used to:
1) Connect a computer to a switch/hub’s normal port.
2) Connect a computer to a cable/DSL modem’s LAN port.
3) Connect a router’s WAN port to a cable/DSL modem’s LAN port.
4) Connect a router’s LAN port to a switch/hub’s uplink port. (normally used for expanding network)
5) Connect 2 switches/hubs with one of the switch/hub using an uplink port and the other one using normal port 

RJ45 connector connections are different in LAN cable as compared to cross cable.
E.g.:
Straight Cable
Pin 1 WhiteOrange Pin 1 WhiteOrange
Pin 2 Orange Pin 2Orange
Pin3 WhiteGreen Pin3 WhiteGreen
Pin4 Blue Pin4 Blue
Pin5 WhiteBlue Pin5 WhiteBlue
Pin 6 Green Pin 6 Green
Pin 7 Brown Pin 7 Brown
Pin 8 WhiteBrown Pin 8 WhiteBrown
Cross Cable:
Wire Becomes
1———————-3
2———————-6
3———————-1
6———————-2
By default the LAN Cable is 100 Meters but you may observe drop of signals after 80 Meters.

ometimes you will use crossover cable, it’s usually used to connect same type of devices.
A crossover cable can be used to: 
1) Connect 2 computers directly.
2) Connect a router’s LAN port to a switch/hub’s normal port. (normally used for expanding network)
3) Connect 2 switches/hubs by using normal port in both switches/hubs

  1. For a typical home network, this isn’t a really big deal — your Internet connection is the bottleneck. But there is a difference between these cables, and you can get faster local network speeds by upgrading.Did you recently pick up a new Lan Network Cable, or did you use an Ethernet cable that came bundled with a modern router or other piece of equipment? It’s probably recent enough that you don’t need to worry.
