Fibra óptica

The video explains how optical fibers support communication by converting electrical signals into light pulses. These pulses travel through glass fibers using total internal reflection, allowing for efficient data transmission. Fiber optic cables are thin, can carry multiple signals, and are more efficient than copper wires.

Explain why fiber optic cables are considered efficient despite some light escaping.

What is the significance of using different wavelengths of light in optical fibers?
