Ethernet cables play a vital role in computer network systems that connect various devices such as computers, routers, modems, and Ethernet switches.
Ethernet cables are still an option in the many wireless networks (WiFi) that are increasingly being used because of their advantages in terms of stability, high speed, and low latency.
In this article, we will review Ethernet cables from their definitions, types, functions, and uses.

What is Ethernet Cable?
Ethernet cable is a type of network cable used to connect various devices in a local network (LAN). This cable is made of copper wire wrapped in an insulating layer and additional shielding to minimize electromagnetic interference.
Compared to wireless networks, Ethernet cables have a number of advantages, including:
- More stable speed: Unlike WiFi which is susceptible to signal interference, Ethernet cables are able to keep connection speeds consistent.
- Low latency: Offering a faster response, it is perfect for activities such as online gaming and high-quality video streaming.
- Higher security: Cable-based networks are more difficult to hack as they require physical access to the network.
The Types of Ethernet Cable
Ethernet cables are available in various categories that differentiate their transmission speed capabilities and bandwidth capacity. Here are some types of Ethernet cables that are often used:
- Cat5e: Capable of transferring data up to 1 Gbps with a bandwidth of 100 MHz. Usually used in home or small office networks.
- Cat6: Supports speeds of up to 10 Gbps over a maximum distance of 55 meters. Has a better ability to reduce interference than Cat5e.
- Cat6a: Capable of transmitting data up to 10 Gbps with a bandwidth of 500 MHz. Ideal for environments with high speed requirements and minimal electromagnetic interference.
- Cat7: Offers bandwidth up to 600 MHz and supports speeds of 10 Gbps. Comes with extra shielding to reduce signal interference.
- Cat8: Designed for speeds up to 40 Gbps with bandwidth up to 2000 MHz. Generally used in data centers and large-scale networks.
The selection of the appropriate Ethernet cable type depends on the network requirements and the devices used, including the type of Ethernet switch installed.
The Functions of Ethernet Cable
As an important part of a wired network system, Ethernet cables have a number of key roles, including:
- Connecting various network devices: Ethernet cables serve to unite devices such as computers, laptops, servers, printers, routers, modems, and switches in one integrated network.
- Maintains connection stability and speed: Unlike WiFi networks that are prone to signal interference, Ethernet cables are able to provide stable and fast connections, especially for activities that require large bandwidth such as gaming and 4K video streaming.
- Improves network security: Since access to a wired network requires a direct physical connection, the level of security is higher compared to wireless networks which are more vulnerable to hacking.
- Relied upon in large-scale networks: Many enterprises and data centers continue to use wired Ethernet due to its higher reliability over wireless networks in supporting large-scale network operations.
The Usefulness of Ethernet Cable
Ethernet switches serve as data distribution centers in networks, and Ethernet cables play an important role in ensuring that switches can work optimally. Here are some important aspects related to the use of Ethernet cables in switches:
1. Improves network performance
Ethernet switches require quality Ethernet cables to distribute data at maximum speed. Cat6 or Cat6a is usually enough for office needs, but if the network is more complex, Cat7 or Cat8 can be a better choice.
2. Minimizes interference and noise
Higher-spec Ethernet cables (such as Cat7 and Cat8) have extra protection against electromagnetic interference (EMI), which often occurs in environments with many electronic devices.
3. Ensuring compatibility with Ethernet switches
Not all Ethernet switches can support all types of Ethernet cables. For example, if a switch only supports speeds up to 1Gbps, then using a Cat8 cable that supports 40 Gbps will not provide any additional benefits.
4. Eases network scalability
By choosing the right cables, Ethernet switch-based networks can be expanded without experiencing bottlenecks in data transfer.
Choosing the right Ethernet cable for an Ethernet switch will have a direct impact on the overall speed and stability of the network.
That’s a review of Ethernet cables from the definition, types, functions, and uses. Hopefully, this article can help you determine the right type of cable that can significantly improve network efficiency and performance.
