Choosing the right cable for your internet or TV connection can be tricky. Ethernet cables and coaxial cables are both commonly used for data transmission, but they serve different purposes and have distinct advantages.
Knowing the differences between these cables is essential for optimal performance. In this article, we’ll break down the key differences between Ethernet and coaxial cables to help you make the best choice for your setup.
What is Ethernet Cable?
Ethernet is a networking technology used to connect devices such as computers, routers, and switches to a local area network (LAN). Ethernet cables are typically made with copper or fiber optic wiring. They come in various categories (like Cat5e, Cat6, and Cat7) and are designed to support high-speed data transfer.
They are widely used for internet connections, local networks, and transferring data between devices. Ethernet cables use RJ45 connectors, a standard for wired network connections.
When you plug an Ethernet cable into a router or modem, it enables the device to access the internet or communicate with other devices on the same network. These cables are also known for their reliability and relatively high speeds compared to wireless options.
What is Coaxial Cable?
A coaxial cable (or coax cable) is a type of cable used to transmit signals for cable TV, internet, and other communication services. Coaxial cables are made up of a central copper conductor, an insulating layer, a metal shield, and an outer plastic cover.
This construction helps minimize signal loss and electromagnetic interference, which is crucial for maintaining signal quality over long distances.
Coax cables are used in cable TV and cable internet services. They are often the go-to choice for connecting modems and routers to internet service providers. These cables can handle both analog and digital signals, making them versatile for various types of data transmission.
Difference Between Ethernet and Coaxial Cables
Understanding the key differences between Ethernet and coaxial cables is crucial for selecting the right option for your network setup. Below are the major points of comparison:
Speed and Bandwidth
Ethernet cables are especially higher-grade cables like Cat6 and Cat7. They offer faster speeds and higher bandwidth than coax cables. Ethernet can support speeds up to 10 Gbps, while coax cable speeds typically max out around 1 Gbps, although this varies with the type of coax used.
Signal Transmission
Ethernet cables transmit digital signals that are optimized for data transfer in a network environment. On the other hand, coaxial cables are designed for both analog and digital signal transmission and are often used for TV and internet services.
Physical Construction
Ethernet cables consist of twisted pairs of copper wires, whereas coaxial cables have a single central conductor surrounded by insulation and shielding. This gives coax cables better protection from interference. However, Ethernet cables are more flexible and lightweight, which makes them easier to install in tight spaces.
Use Cases
Ethernet cables are commonly used in computer networking, connecting devices like computers, routers, and network switches. Coaxial cables are more often used for cable internet, cable TV, and satellite TV installations.
Distance and Coverage
Ethernet cables generally have a shorter maximum range compared to coax cables. While an Ethernet cable can effectively run up to 100 meters without signal degradation, coax cables can cover longer distances, making them ideal for connecting devices over large areas.
Speed and Performance
Ethernet cables can offer higher speeds, especially with modern standards like Cat6 and Cat7 cables. On the other hand, Coax cables are often limited to 1 Gbps speeds and can experience interference if used improperly.
Coaxial Cable vs. Ethernet: Which One Should You Use?
Choosing between coaxial cables and Ethernet cables comes down to the specific application you need them for. Here's a breakdown to help you decide:
For Internet Connections
If you're setting up a home or office internet connection, Ethernet cables are the ideal choice due to their higher speeds and reliable performance. For cable TV or internet services provided by companies, you may need a coaxial cable to connect to your modem or router.
For Networking
Ethernet is the go-to option for local area networks (LANs), especially in wired environments where speed and reliability are key. Whether it's for cable Ethernet coaxial adapters or ethernet over coaxial systems, Ethernet cables are your best bet for creating a fast, stable network.
For Cable TV and Internet
Coaxial cables are essential for cable TV and internet connections. They are commonly used to carry the signal from the wall outlet to your modem or router. If you’re using services like cable TV or cable internet, a coax cable router connection is necessary.
Conclusion
Both Ethernet cables and coaxial cables serve different functions and excel in distinct areas. When setting up a network for computers and high-speed internet, Ethernet is the clear winner. However, coaxial cable remains the best choice for cable TV and internet services. Choose wisely based on your specific needs.

Frequently Asked Questions
What is the difference between coax and Ethernet?
Coaxial cables are used for signal transmission (TV, cable internet), while Ethernet cables are used for network connectivity. Ethernet offers higher speeds, while coax is more commonly used in cable TV and internet connections.
Is an Ethernet cable also known as a coaxial cable?
No, they are different. Ethernet cables are for networking, while coaxial cables are for TV and internet signal transmission.
How does coax to Ethernet work?
Coax to Ethernet conversion requires special adapters or network devices like MoCA (Multimedia over Coax Alliance), which allow you to use coaxial cable as an Ethernet network medium.
Is it better to have a longer coaxial cable or Ethernet cable?
For network setups, Ethernet cables should be kept short for optimal speed. For coaxial cable internet and TV, longer lengths are generally fine but may require signal amplifiers for long runs.
How far can a coax cable run?
Coaxial cables can run much farther than Ethernet cables, typically up to 500 meters, though performance may degrade over long distances.
Is coaxial cable fast or slow?
Coaxial cable speeds vary but are typically slower than modern Ethernet cables. The maximum coax max speed is often limited to 1 Gbps.
