Difference Between Patch and Crossover Cable (With Table)

In the era of modern technology, high-speed internet connection, the use of cables and connectors has increased a lot. The cables we buy from the market look the same but have a manufacturing difference under the insulating materials. After purchasing the cables, we find that the cables are not getting connected to the devices we targeted. So to understand the difference between the cables here are some facts about them. Here are some basic differences between the patch and the crossover cables.

Patch Cable vs Crossover Cable

The difference between the patch cables and the crossover cables is that the cables are made by different procedures. The patch cables are a straight cable between the ends, but the crossover cables have many swaps between the two ends. So during the connection of these cables with connectors, it makes differences in the pins of the connectors.

Patch cables are straight cables that have the same numbering of wires from one end to the other. It is mainly used to connect different devices. It is mainly used for internet connections domestically. This wire is first connected to the connectors and then connected with computers and routers to provide an internet connection domestically.

Crossover cables are the cables whose sequences are not the same throughout the cable. In this, the wires within the cables are swapped r crossover inside the skin. So they have different output number pins as of the input. So they are a little bit difficult to connect without the help of a professional.

What is Patch Cable?

Patch cables are straight cables that have the same numbering of wires from one end to the other. For example, a wire with PIN 1 at one end will remain as the wire with PIN 1 at the other end also. So when connecting these cables with connectors, it is very easy to connect. At both ends, the same connectors can be attached due to the same connecting numbers.  

It is very famous due to its feature of connecting different devices. It is mainly used for internet connections domestically. This wire is first connected to the connectors and then connected with computers and routers to provide an internet connection domestically.

These types of cables are also used to connect internet hubs with routers at home and then from routers to the computer system or any other devices. Some commonly used patch cables are Cat5, Cat5e, Cat6, etc. An example of this type of connection is a connecter Rj45 is connected with the cat cable on both ends of the cable, and then one side is connected to the internet hub and the other to the router. Then similarly, another cable with an Rj45 connector on both sides is connected to the router and then to the computer. In this way, the internet connection is made from the hub to the user’s system.

What is Crossover Cable?

Crossover cables are the cables whose sequences are not the same throughout the cable. In this, the wires within the cables are swapped r crossover inside the skin. So they have different output number pins as of the input. So they are a little bit difficult to connect without the help of a professional. 

These cables are used to connect the same devices. Sometimes we need to share the internet from one pc if the other pc does not have an internet connection. So to connect pc to pc or from any other similar devices we use crossover cables.

Both the ends of the cable consist of different connectors due to the difference in the output serial of the wires in the cable. So taking an example, a rollover cable is connected to T568A on one side and T568B on the other side. 

Different serial pinouts can be best understood from the example. The wire at PIN 1 at one end can be found at PIN 3 on the other end. Some examples of the crossover cables available in the market are null-modem cable, rollover cable, etc.

Main Differences Between Patch and Crossover Cable

  1. A patch cable is a straight cable from one end to the other, whereas a crossover cable is a crossover or swap type cable it swaps between the ends.
  2. Patch cable can connect two different devices. On the other hand, a crossover cable can connect two same devices.
  3. Patch cables are used to connect devices like a computer to switch, hub and routers, etc. on the other hand, crossover cables are used to connect devices like pc to pc, switch to switch, etc.
  4. Patch cables use the same types of connectors on both sides, like RJ455 connectors on both ends. On the other hand, crossover cables need different kinds of connectors on both sides, like T568A on one side and T568B on the other side.
  5. Examples of patch cables are Cat5, Cat5e, Cat6, and examples of crossover cables are null-modem cable, rollover cable, etc.

Conclusion

Both patch cables and crossover cables are used to connect one device with the other. But the difference is that one can connect similar devices only, whereas the other can connect different devices. One has the same PINs on both input and output, whereas the other has different PINs on input and output. These are the different factors from which two types of cables are discovered and are being used in the market. Patch cables are more famous and used concerning crossover cables.
