Fiber-Optic Communications Quiz

Why are fibers used instead of metal wires in fiber-optic communications?

How are glass optical fibers typically made?

In addition to fiber-optic communications, for what other purposes are optical fibers used?

What advantage do optical fibers have over metal wires when it comes to signal transmission?

What is a key problem from which metal wires suffer but fibers are immune to?

Fiber-Optic Communications

Fibers are used instead of metal wires due to their ability to transmit signals over long distances without significant degradation, allowing for faster and more reliable data transfer.
Glass optical fibers are typically made by heating and stretching silica-based glass rods, which are then drawn into thin fibers.

Optical Fiber Applications

Optical fibers are used in medical applications, such as endoscopy, and in sensing technologies, such as temperature and pressure sensors.
They are also used in industrial applications, including distance measurement and vibration detection.

Signal Transmission Advantages

Optical fibers have a higher bandwidth capacity than metal wires, allowing for faster data transfer rates.
They are less susceptible to electromagnetic interference, reducing signal degradation and noise.

Metal Wire Limitations

Metal wires suffer from signal attenuation, which is the gradual weakening of signal strength over distance, but optical fibers are immune to this issue.
Metal wires are also prone to electromagnetic interference, which can disrupt signal transmission, but fibers are resistant to this problem.
