• Higher speed: Optical fibre cables transmit data at much higher speed than copper wires. This is because the speed of light is greater than the speed of electrons. Optical fibre cables have a much larger bandwidth of over 60 Tbps in comparison to 10 Gbps bandwidth of copper wires .
• Longer distance: Optical fibre cables can carry data over longer distances without losing signal quality or strength. Copper cables can only carry signals about 100 meters, while some singlemode optical fibre cables can carry more data up to 25 miles.
• More reliable: Optical fibre 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 fibre cables are more difficult to tap or intercept than copper wires. This is because optical fibre 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 fibre cable will cause noticeable loss of light and alert the network operators.
• More durable: Optical fibre 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 copper connection please ask your ISP to switch to optical fibre connection.
