Optical Network Quiz

What is the main advantage of fiber optic networks over traditional copper wire networks?

• Higher bandwidth and faster data transmission

• Less secure and more prone to interference

• More expensive to install and maintain

• Slower data transmission and lower bandwidth

Explain the concept of total internal reflection in the context of fiber optic networks.

• Total internal reflection only happens in glass and not in other materials

• Total internal reflection is the phenomenon where light is completely reflected within a medium, such as the core of a fiber optic cable, due to the angle of incidence being greater than the critical angle.

• Total internal reflection is the result of light passing through the cladding of a fiber optic cable

• Total external reflection occurs when light passes through the core of a fiber optic cable

What are the two main components of a fiber optic network?

• Router and modem

• Copper wire and Ethernet cable

• Satellite dish and antenna

• Optical transmitter and optical receiver

Describe the process of data transmission in a fiber optic network.

• Sending light pulses through copper cables

• Converting electrical signals into light pulses, transmitting through fiber optic cables, and converting back into electrical signals at the receiving end.

• Converting light pulses into electrical signals at the receiving end

• Using radio waves for data transmission

What is the role of a fiber optic coupler in a network?

• Regulating the flow of data packets

• Amplifying electrical signals

• Converting digital signals to analog

• Combining or splitting optical signals

Explain the difference between single-mode and multi-mode fiber optics.

• Single-mode fiber has a larger core, allowing multiple modes of light to propagate

• Multi-mode fiber has a smaller core, allowing only one mode of light to propagate

• Single-mode fiber has a smaller core, allowing only one mode of light to propagate, while multi-mode fiber has a larger core, allowing multiple modes of light to propagate.

• Single-mode fiber is more suitable for short distances, while multi-mode fiber is better for long distances

What are the main factors that can affect the performance of a fiber optic network?

• Length of the cables, brand of the routers, and time of day

• Signal loss, dispersion, and bending

• Number of users, type of computer, and internet speed

• Color of the cables, temperature, and humidity

Discuss the concept of fiber optic splicing and its importance in network installation.

• Fiber optic splicing is not important in network installation.

• Fiber optic splicing is the process of joining two fiber optic cables together. It is important in network installation to ensure seamless connectivity and minimal signal loss.

• Fiber optic splicing is only necessary for small networks.

• Fiber optic splicing is the process of separating fiber optic cables.

What are the different types of fiber optic cables used in network installations?

• Coaxial and twisted pair fiber

• Plastic and rubber fiber

• Copper and aluminum fiber

• Single-mode fiber and multi-mode fiber

Describe the process of fiber optic network maintenance and troubleshooting.

• Using outdated equipment for maintenance

• Ignoring any issues that arise

• Replacing all the cables regularly

• Regular inspection, cleaning, testing, identifying and resolving issues
