Crossover Cable is simply related to the connection of two devices of the same technology or systems like DCE-DCE or DTE-DTE, basically connecting asymmetrical devices like DTE-DCE cables are known as cross-link cables. IBM (International Business Machines Corporation) introduced such a distinction of all the devices.
In contrast, straight-through cables connect complimentary system devices by using direct wiring e.g. a computer to a switch plug but the crossing of cables in an adapter connection allows:
- Connecting two or more routers or switches to work as one wider device.
- Connecting the output of one device to the input of the other device.
- Allowing two DTE devices to communicate without an interlinking cable or hub know e.g. PCs.
Straight through cables worked on most of the devices or applications, but crossover cable is also used sometimes. In straight-through, both pins of one and another end are matched like pin 1 or pin 1, Pin 2 or pin 2, etc. In straight-through cables, a particular color cable attached to a pin number at both ends yet.

In crossover cables, all pins are not similar, all the transmitters are exchanged at the terminations. For example, if pin A on the first end goes to pin B on the other, then pin B on the first-hand goes to pin A on the other. Such cables of the crossover are electrically consistent, which means they can run identically nevertheless of which way you plug them in. In crossover cables, a particular color cable connects to one pin at one end and a different pin at the other.
Difference between Crossover and Straight through
As we come to the difference between both, in straight-through cables, when we talk about the cat5e cables patch, it is used to connect printers, computers and other client devices of the network to the hub. These cables are most repeatedly used to connect a host to the client. And, in crossover cables, these are much like straight through, expect that RX and TX are crossed. Taking 568-B standards as an example, you will see that pin A goes on the first connector to pin B on the second connector.
Nowadays, many devices have auto switch technology of sensor that discerns the devices and cables and crosses pairs when required.
Other types of Cables
Basically, these cables are used for carrying Ethernet, some of them are cat8, 7, 6a, cat 6 and cat 5 and the RJ45 connector is used most widely. When we bought an Ethernet connection. Cables are free with equipment that uses the connectivity of Ethernet in some way or another. These cables are carrying with Ethernet in the twisted method. This method of twisting the cables together allows the balance of the currents.
In this method, a huge amount of data can be easily transmitted over the substantial lengths without requiring excessive provisions. Many different lengths of cables are available as patch cables in Ethernet cables or the cable own are available for integrating with buildings, systems, etc. This termination can be made for the required connector using a tool named the crimp tool.
Earlier, there is no shield in cables, but now these cables are shielded for improving performance. For example, an unshielded twisted pair (UTP) cable is not worked for a long run between the systems but foil shielded cables (FTP) are long run between these systems. As a result, FTP is better than UTP cables.
There are two types of basic Ethernet:
- Solid Cables- This type of cables are not more flexible, but also more durable. This made it best for use for long time installation of cables under flooring or embedded in walls.
- Stranded Cables- This type of cables is more flexible than solid cables, but it is not used for Ethernet cables, often it is an idea of leads patch at the general connection to personal computers, etc.
