How can optical fiber be used for communication?

Answer 1

Optical fibers can be used for communication,Instead of electrical signals fibers is used to send light signal

Light signals travel at the same speed as electrical signals and can be sent over long distances through fibers with little loss.

Optical fibers are used for communication by transmitting data as pulses of light through the fiber's core. This light signal carries information encoded in its intensity or frequency. The fiber's core is typically made of glass or plastic with high optical clarity to minimize signal loss. Optical fibers offer high bandwidth, low attenuation, and resistance to electromagnetic interference, making them ideal for long-distance communication, such as in telecommunications networks, internet connections, and cable television systems.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
