Why is fiber faster than coax?

Answered by Antonio Sutton

Fiber-optic cables are faster than coaxial cables due to several key factors. Firstly, the use of light as the delivery method allows fiber-optic cables to transmit information at a much higher speed. Light travels at an incredibly fast speed, nearly 186,000 miles per second in a vacuum, and although it slows down slightly in a fiber-optic cable, it still maintains a tremendous speed. In contrast, coaxial cables use electrical signals to transmit data, which are slower than the speed of light.

Another reason fiber is faster than coax is its higher bandwidth capacity. Bandwidth refers to the amount of data that can be transmitted over a network connection in a given amount of time. Fiber-optic cables have a much larger bandwidth capacity compared to coaxial cables. This means that fiber can handle a significantly higher volume of data simultaneously, resulting in faster transmission speeds.

Furthermore, fiber-optic cables provide a dedicated connection for internet access. This means that the connection is not shared with other users or devices, ensuring that the full bandwidth is available for the user’s needs. Coaxial cables, on the other hand, often involve shared connections, which can lead to congestion and slower speeds during peak usage periods.

The nature of fiber-optic cables also allows for minimal signal degradation over long distances. Light signals in fiber-optic cables can travel over much longer distances without significant loss of signal quality compared to electrical signals in coaxial cables. This allows fiber to maintain its high-speed transmission capabilities over greater distances.

In my personal experience, I have witnessed the difference in speed between fiber and coaxial connections. I previously had a coaxial cable internet connection, and while it served its purpose, the speed was noticeably slower compared to the fiber-optic connection I currently have. Downloads and uploads are much faster, streaming high-definition videos is seamless, and online gaming experiences are smoother with fiber. The dedicated connection also ensures that my internet speed remains consistent, even during peak usage times.

Fiber-optic cables are faster than coaxial cables due to the use of light as the delivery method, higher bandwidth capacity, dedicated connections, and minimal signal degradation over long distances. These factors combine to provide high-speed internet access that remains consistently fast, making fiber-optic cables the preferred choice for users who require fast and reliable internet connections.
