Straight Through Cables vs Crossover Cables: Key Difference

What is Straight Through Cable?

Straight-through cable is a type of CAT5 with RJ-45 connectors at each end, and each has the same pin out. It is in accordance with either the T568A or T568B standards. It uses the same color code throughout the LAN for consistency. This type of twisted-pair cable is used in LAN to connect a computer or a network hub such as a router. It is one of the most common types of network cable.

What Is Crossover Cable?

A Crossover cable is a type of CAT 5 where one end isT568A configuration and the other end as T568BConfiguration. In this type of cable connection, Pin 1 is crossed with Pin 3, and Pin 2 is crossed with Pin 6.

Crossover cable is used to connect two or more computing devices. The internal wiring of crossover cables reverses the transmission and receive signals. It is widely used to connect two devices of the same type: e.g., two computers or two switches to each other.

In regard to physical appearance, Crossover Ethernet cables are very much similar to regular Ethernet cables. Still, they are different with regard to the order with which the wires are arranged. This type of Ethernet cable is made to connect to network devices of the same kind over Ethernet directly. Crossover cables are mostly used to connect two hosts directly.

When to use Straight Through Cable?

Here are applications where you should use Crossover Cable:

• It helps you to connect a computer to a switch/hub's normal port.
• You can use it to connect a computer to a cable/DSL modem's LAN port.
• It allows you to connect a router's WAN port to a cable/DSL modem's LAN port.
• Connect 2 switches or hubs with one of the hub or switch using an upline port and the other one using a normal port.

When to use Crossover Cable?

Here is an application where you should use Crossover Cable:

• It can use a computer to a computer with no switch or hub.
• Network devise to the network device. For example, the route to the router.
• Crossover cable enables one to establish a direct connection between two computing devices using Ethernet ports.
• It Connects two computers directly.
• You can connect two hubs/switches by using the normal port in both switches and hubs.

Straight Through vs. Crossover Cable, which one to choose?

The selection or network cable should be done based on your application. If you want your cable to connect to your computer and printer together, you need a crossover cable. If you have several computers and a printer, you should buy a switch.

All the computers connected to the switch with a straight-through cable and printer should be connected to the switch with a straight-through cable.
