Optical fiber and copper wire are two common types of cables used for data transmission. However, optical fiber has many advantages over copper wire that make it a superior choice for many applications. Here are some of the benefits of using optical fiber instead of copper wire:

Higher speed: Optical fiber cables transmit data at a much higher speed than copper wires. This is because the speed of light is greater than the speed of electrons. Optical fiber cables have a much larger bandwidth of over 60 Tbps in comparison to the 10 Gbps bandwidth of copper wires.
Longer distance: Optical fiber cables can carry data over longer distances without losing signal quality or strength. Copper cables can only carry signals for about 100 meters, while some single-mode optical fiber cables can carry more data for up to 25 miles.
More reliable: Optical fiber cables are more resistant to environmental factors such as temperature, moisture, corrosion, electromagnetic interference (EMI), and noise. Copper wires are prone to these factors and can degrade or distort the data signals over time.
More secure: Optical fiber cables are more difficult to tap or intercept than copper wires. This is because optical fiber cables transmit light signals that do not leak out of the cable, while copper wires emit electromagnetic signals that can be picked up by external devices. Any attempt to break into an optical fiber cable will cause a noticeable loss of light and alert the network operators.
More durable: Optical fiber cables are stronger and lighter than copper wires. They can withstand more pressure and stress without breaking or bending. They also require less maintenance and replacement than copper wires.
In conclusion, If you are still on a copper connection, please ask your ISP to switch to an optical fiber connection.
