Ethernet Over Coax (Moca) – How Does It Work?


Modern digital communication has come a long way compared to what it used to be in the past. Today we have high-speed internet powered by different instruments and cables, one of which is Ethernet. Ethernet over coax has been around for a long time, but not many internet users know what it really means or how it works. An Ethernet network works with different cables, including a set of coaxial cables. This makes the technology a complex one.

This article will teach you all you need to know about Ethernet and how it works.

What Is An Ethernet Network?

An Ethernet network is a technology that divides data into frames or packets, with each frame containing actual data or metadata about the receiver and sender. It also has separate backup data that checks for errors. Ethernet networks have a device that analyses received data, backup data, and verifies corrupted files before such data is added to decided frames to produce constant streams.

Ethernet is mostly used for Local Area Networks (LAN) or Metropolitan Area Networks (MAN). For LAN, the network is linked to devices within a single building or several buildings in a neighborhood. As for LAN, the network is used to link devices in an entire city.

Despite its introduction more than three decades ago, it continues to be the widely used technology for linking LAN devices because of its stability and compatibility with networking protocols. When compared to other internet networks, Ethernet has several benefits. You can verify different frames and identify faulty packets before they corrupt other packets. Tapping data from specific servers is also much easier using Ethernet than any other network.

The Purpose of Ethernet Cables

Over the years, Ethernet has been wired with Coaxial cables that are far more efficient than heavily shielded cables that were once the standard. Ethernet over coax cables connects routers, computers, and LAN switches. Today, there are different types of Ethernet cables in use today, but the most common ones are:

  • Category 5 cables
  • Category 6 cables

These cables can be used to connect only one computer, but advanced models can connect two cables at once. Also, note that the coaxial cables are of two forms. There are solid form cables known for faster and improved internet speed and premium protection from power surges. Solid form coaxial cables are commonly used by business networks inside lab floors and office walls.

Then you have the stranded cable, mostly used for trips and at homes.

The Purpose Of Coaxial Cables

Coaxial cables are an essential part of an Ethernet network. These cables serve video and audio functions. Homes with an Ethernet network have one coax cable outlet per room that connects the signal from a wall outlet to a cable box or TV. These cables used to be attached to digital converter boxes or TV antennas in the past but not anymore. Today, modern coaxial cables can be connected directly and don’t need a Digital box, TV, or VCR.

How Does Ethernet Work?

To fully understand how an Ethernet network works, you first need to understand the hardware that makes up Ethernet systems. There are three major units you should know about, which are:

  • Ethernet Cards
  • Ethernet Cables
  • Ethernet Routers and Hubs

The card or adapter is installed inside the computer so it can connect to the network through an Ethernet cable. This hardware is basically a transmitter that transmits and receives packages across the internet network.

The cables have been addressed above, so we don’t have to explain what they do in detail. However, please take note that they continue several wires that allow for the free flow of data to and from your computer.

Then you have to the router or hub for directing intra-computer data across a network so the designated computer can share it and also serve as a link to the internet broadband.

How Ethernet Revolutionized The Internet

The introduction of Ethernet in the 80s revolutionized the internet because it made access cheaper, stable, and efficient. The network’s router not only connected computers it also served as a link to the internet using signals. Sending and receiving data and routing them to their appropriate computers became much easier than using independent computer networks. This made internet technology more affordable to homes and businesses.

Today, internet modems use Ethernet technology to connect computers to the internet and remain a building block for future technological advancements.

Benefit Of Ethernet Technology

Speed: Data transfer using Ethernet is fast compared to other wireless networks. This is because it uses a one-on-one connection to easily achieve data transfer speeds of 10Gbps- 100 Gbps

Efficiency: The technology is efficient since it consumes less power. Ethernet consumes less power than a WiFi connection.

Quality Data Transfer: You can transfer data without degrading the quality. While some other networks compress data to send them, Ethernet networks will send your raw file just as you send them with no drop in quality.
