Fiber Optic Cables and Their Applications

The video tutorial discusses fiber optic cables, highlighting their advanced technology and ability to avoid electromagnetic interference. It explores why fiber optics have not replaced other cables, citing cost and fragility as major factors. The tutorial explains how light propagates through fiber optics and their applications in network infrastructure, particularly in high-traffic areas. Despite their advantages, fiber optics are not always necessary for short distances or less critical data transmission.

What is one of the main reasons fiber optic cables are considered advanced?

• They are the cheapest option.

• They are made of plastic.

• They use light to transmit data.

• They are the oldest technology.

What is the primary material used in fiber optic cables?

• Glass

• Plastic

• Wood

• Metal

How do fiber optic cables avoid electromagnetic interference?

• By being buried underground.

• By being coated with metal.

• By using light instead of electricity.

• By using thicker glass.

What happens to light as it travels through a fiber optic cable?

• It stops moving.

• It bounces off the walls.

• It gets absorbed.

• It changes color.

Why haven't fiber optic cables replaced UTP or coaxial cables?

• They are too colorful.

• They are too short.

• They are too heavy.

• They are too expensive and fragile.

What is a significant challenge in manufacturing fiber optic cables?

• Finding the right color.
