Fiber Optic vs. Ethernet: Which is the Better Choice for Your Network?

In modern communication networks, fiber optic and Ethernet cables are two popular types of cables used for data transmission. Despite the fact that they both serve the same purpose, there are many differences between the two in terms of their physical structure, performance, and usage. This article delves into the primary differences between optical fiber and Ethernet cables.

Fiber Optic cable is a type of cable that transmits information using light rather than electrical signals, which makes it faster and more efficient. They accomplish this by using a glass fiber core in each fiber optic cable. Its core enables a beam of light (or numerous beams in the case of multimode cables) to bounce back and forth down the cable at the speed of light, theoretically delivering information as quickly as is physically possible. The cable is made to transmit data across great distances, and is perfect for telecommunications and high-speed internet applications. It can be utilized by local area networks (LANs), wide area networks (WANs), and international communication infrastructures.

Ethernet cable is a type of cable that uses electrical signals to transmit data. The majority of Ethernet cables are constructed from twisted pairs of copper or aluminum wiring, meaning they use electricity to transmit information along the cable. Those wires within the cable itself are protected by various levels and types of shielding, including foil shielding, braided shielding, plastic splines, and combinations of all three. Due to its low cost and simplicity of use, Ethernet cable is the most popular type of networking cable and is often used in LANs.

Compared to Ethernet cables, optical fiber cables have more benefits, such as quicker data transfer rates, longer transmission lengths, and bigger bandwidth capacities. Moreover, they are less vulnerable to electromagnetic interference, which can cause signal degradation or loss. Additionally, optical fiber cables are resistant to electrical interference and less prone to start fires because they don't use electricity. However, optic fiber is less practicable for small-scale applications since it is more expensive and challenging to install.

Ethernet cables, on the other hand, are more affordable and easy to install, making them ideal for smaller-scale local networks. Most LAN applications can handle data transfers at speeds of up to 10 gigabits per second across Ethernet cables. The downside of Ethernet cables is that they can only transmit data over shorter distances and are more susceptible to electromagnetic interference.

The differences mentioned above make it complicated to choose the best cable. The size of the network and if it's necessary to send data across great distances should be taken into account first. Fiber optic connections are great for bigger networks or communication applications, whilst Ethernet cables are better suited for local LANs. The price and convenience of installation should also be taken into account, as fiber optic cables are frequently more expensive and challenging to install.
