The Advantages and Disadvantages of Using Category 6 Cable

Introducing Category 6 cable is to establish a standard for Gigabit Ethernet. Category 6 cable, also known as Cat-6, is compatible with Category 5 / 5e and Category 3 cable standards.

It can create a high-speed computer network and operate at optimal performance if other network components are compatible with gigabit speeds.


1. Speed ​​and performance

The cable can handle speed performance up to 250MHZ. This fast performance allows it to be used with a fast ethernet network that includes Gigabit Ethernet and 10 Gigabit Ethernet.

 I introduced the entire generation of Cat 6 able to complement Gigabit Ethernet, which includes interface cards, patch panels, routers, switches, and other components developed to achieve a full gigabit network. 

Many IT professionals found that Cat 6 cable provides quick network performance and can deliver gigabit speeds.

2. Similar structure with Cat 5 cable

Cat 6 cable has a structure similar to Cat 5 and Cat 5e. Cat 6, Cat 5, and Cat 5e cables have eight wires that are intertwined to form four pairs. 

The difference is that one pair of cables in Cat 6 cable does not contact each other so that it can produce twice the capacity of Cat 5 and Cat 5e.

3. Backward compatible

Cat 6 cable plug and port are the same as Cat 5 and Cat 5e. Therefore, it can be connected to any port or connection that supports both cables

If you use the Cat 5 port, it will not produce the maximum speed that it can handle. Instead, it will run at computer or cable speed. However, the speed will be acceptable.

4. Upgradable

If upgrading to a more optimal network, Cat 6 cable should be included in part of the upgrade.

 Cat 6 cable will not run at full speed if other units on the network do not support gigabit speeds. 

Small businesses that are just starting out should Cat 6 cable as it is becoming the industry standard.


1. Expensive

Cat 6 cable is much more expensive than Cat 5e cable. If the cable does not show a noticeable improvement in your network, it is not worth the investment.

 In most cases, it is more sensible to use Cat 5 e because it is cheaper and offers excellent performance. Cat 5e cable is also available in different colors.

2. Does not guarantee maximum speed

Users often misunderstand that buying a Cat 6 cable will give them the entire gigabit network. 

Cat 6 cable will only produce maximum speed if all network components can operate at gigabit speed. 

If one component is not gigabit rated, your network will operate at the slowest speed of the device.

Most of the time, it can persuade the average user to buy Cat 6 cable without really knowing if it will impact their network. Therefore, do your research before deciding.
