Difference Between Coaxial Cables vs Ethernet Cables

What is Ethernet?

Ethernet cables are the most common type of networking cables used today. They typically consist of four pairs of twisted copper wires encased in a plastic sheath. Ethernet cables are known for their reliability and versatility. This makes them ideal for connecting devices such as computers, routers, switches, and other networking equipment. The most common categories of ethernet cables are the Cat5e, Cat6, and Cat6a. These cables are available in different shapes and forms such as bulk cables and patch cords. 

Moreover, the bulk ethernet cables are also available in different conductors, shielding types, and outer jackets. For most local area networking, these are the go-to cables for all types of use cases from residential to commercial. 

What is Coaxial Cable?

Coaxial cables, often referred to as coax cables, feature a central conductor which is usually made of copper. The central conductor is surrounded by a layer of insulation, a conductive shield, and an outer insulating layer. 

Coaxial cables are commonly used for transmitting cable television signals, internet connections, and other data transmissions over long distances. It is worth mentioning that this type of cable were first introduced in the 1880s and today most of them are replaced by high-speed ethernet cables. 

Difference Between Ethernet and Coaxial Cables

There are three main types of differences between ethernet vs coaxial cables. Namely, differences in physical structure, speed and bandwidth, and difference in use cases. Read further to find out more in detail. 

Physical Structure

Ethernet cables consist of 4 twisted pairs of copper wires. The twisted pair design of these cables helps reduce electromagnetic interference and crosstalk. 

In contrast, coaxial cables have a central conductor surrounded by insulation and a shield, offering better protection against external interference.

Speed and Bandwidth

Ethernet cables, especially those using Cat6 or higher standards, offer higher data transfer speeds compared to coaxial cables. Ethernet speeds can range from 100 Mbps (Cat5e) to 10 Gbps (Cat6a). The actual speed of ethernet cables depends on the category and network infrastructure. 

Coaxial cables, while capable of high speeds, generally have lower maximum bandwidth compared to Ethernet. Data transfer speed on an average coax cables reaches up to 1 Gbps.

Use Cases

Ethernet cables are commonly used in home and office networks, data centers, and enterprise environments where high-speed and reliable connections are essential. 

Coaxial cables, on the other hand, are often used for cable television connections, broadband internet access, and long-distance transmissions. But in the recent years, coax cables have been retired from internet connection applications and now they are almost always used for Cable Television applications. 

Coax vs. Ethernet: Speed Comparison

Speed of Coaxial Cable

Coaxial cables can support various speeds, with typical broadband internet connections ranging from 100 Mbps to 1 Gbps. However, the actual speed may vary depending on factors such as signal quality, distance, and network congestion.

Speed of Ethernet Cable

Ethernet cables, particularly those conforming to Cat6 or higher standards, offer faster and more consistent speeds compared to coaxial cables. Gigabit Ethernet, for example, supports data rates of up to 1 Gbps, while 10 Gigabit Ethernet can achieve speeds of 10 Gbps or higher.

Is Coaxial Better Than Ethernet?

Determining whether coaxial is better than Ethernet depends on the specific use case and requirements. Coaxial cables excel in certain areas, such as long-distance transmissions and compatibility with existing infrastructure for services like cable TV and Internet. They are also easier to install and set up for home networking, making them a convenient choice for many users. 

However, when it comes to speed and performance, Ethernet cables, particularly those using Cat6 or higher standards, offer higher data transfer speeds, lower latency, and better support for advanced networking technologies like Power over Ethernet (PoE) and Ethernet switches. Ethernet cables are also more resistant to electromagnetic interference and crosstalk due to their twisted pair design, which can result in more reliable and stable network connections.

Which One Do You Need? Coaxial or Ethernet

The choice between coaxial and Ethernet cables depends on factors such as speed requirements, network infrastructure, and intended use. While coaxial cables may be sufficient for basic internet access and cable TV connections, Ethernet cables are preferred for high-speed data transfers, gaming, video streaming, and other bandwidth-intensive applications.

When choosing between coaxial and Ethernet cables, several considerations come into play. The primary factor is the intended use and the specific requirements of the network. If the priority is long-distance transmissions or leveraging existing infrastructure for cable TV and internet services, coaxial cables may be the better choice. Their simplicity in installation and setup, especially for home networking, also makes them appealing in certain scenarios.
