Fiber Optic Technology Concepts

The video tutorial explains fiber optics as a method of network communication using light instead of electrical signals. It highlights the advantages of fiber optics, such as immunity to radio frequency interference and the ability to transmit signals over long distances. The tutorial covers the structure of fiber optic cables, including the core, cladding, and protective coating. It also discusses different types of fiber optic cables, namely multi-mode and single-mode fibers, and their respective uses and characteristics.

What is one of the main advantages of using fiber optics over copper cables?

• Lower cost

• Longer distance signal transmission

• Easier installation

• Higher radio frequency interference

What is used to create the light in fiber optic cables?

• LED or laser

• Incandescent bulb

• Fluorescent light

• Halogen lamp

What is the purpose of the cladding in a fiber optic cable?

• To protect the core

• To transmit electrical signals

• To generate light

• To reflect light back into the core

What is the function of the protective ferrule in an SC connector?

• To transmit electrical signals

• To generate light

• To increase the signal strength

• To protect the fiber during connection and disconnection

Which type of fiber optic cable is typically used for short-range communication?

• Hybrid fiber

• Single-mode fiber

• Multi-mode fiber

• Plastic optical fiber

What is the typical maximum distance for multi-mode fiber communication?

• 10 kilometers

• 2 kilometers

• 100 kilometers

• 50 kilometers

Why is single-mode fiber more expensive than multi-mode fiber?

• It requires stronger light sources like lasers

• It is used for shorter distances

• It uses cheaper light sources

• It has a larger core

What is the main characteristic of single-mode fiber?

• It allows multiple modes of light to pass through

• It has a larger core than multi-mode fiber

• It only allows one mode of light to transmit

• It is used for short-range communication

Which type of fiber optic cable is commonly used for long-distance communication?

• Single-mode fiber

• Plastic optical fiber

• Multi-mode fiber

• Hybrid fiber

What is the maximum distance some implementations of Ethernet can run over single-mode fiber?

• 50 kilometers

• 2 kilometers

• 100 kilometers

• 10 kilometers
