JARINGAN FIBER OPTIK

What is the primary material used in fiber optic cables?

• Rubber insulation

• Glass or plastic fibers

• Copper wires

• Aluminum strands

Which of the following is a key advantage of fiber optics over copper cables?

• Easier to splice and repair than copper cables.

• Less susceptibility to electromagnetic interference.

• Higher bandwidth and faster data transmission.

• Lower installation costs compared to copper cables.

What does the term 'total internal reflection' refer to in fiber optics?

• Light escaping from the fiber optic cable

• Light being absorbed by the fiber material

• Total internal reflection is the phenomenon that allows light to be completely reflected within a fiber optic cable, enabling efficient signal transmission.

• Light bending at the core-cladding interface

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

• Multi-mode fiber optic cable

• Copper coaxial cable

• Plastic optical fiber

• Single-mode fiber optic cable

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

• To reflect light and maintain signal integrity within the core.

• To enhance the color of the cable for aesthetic purposes.

• To provide insulation against electrical interference.

• To increase the weight of the cable for stability.

Which of the following is NOT a type of fiber optic connector?

• RJ45

• SC

• USB

• LC

What is the main function of a fiber optic transceiver?

• To store data in a digital format.

• To convert electrical signals to optical signals and vice versa for data transmission.

• To filter out noise from electrical signals.

• To amplify optical signals for longer distances.

In fiber optics, what does 'bandwidth' refer to?

• The maximum data transfer rate of a communication channel.

• The physical length of the fiber optic cable.

• The color of the fiber optic strands.

• The type of light used in fiber optics.

What is the typical wavelength range for fiber optic communication?

• 400 nm to 700 nm

• 1600 nm to 2000 nm

• 300 nm to 500 nm
