Quiz Fiber Optik Kelas XI TKJ

What is meant by fiber optic?

• Metal cable that transmits electrical signals

• Plastic cable that transmits sound signals

• Glass or plastic cable that transmits light signals

• Copper cable for analog signals

Which is the main advantage of using fiber optics?

• Low cost

• Resistant to electromagnetic interference

• Easy to install

• Low bandwidth capacity

Light in optical fibers is guided through the process of:

• Diffraction

• Reflection

• Total internal reflection

• Refraction

Which of the following is a type of fiber optic cable?

• Single-mode and multi-mode

• Twisted pair and coaxial

• Shielded and unshielded

• Copper and aluminum

The type of fiber optic used for long-distance transmission is:

• Multi-mode fiber

• Single-mode fiber

• Step-index fiber

• Plastic optical fiber

The phenomenon of total internal reflection occurs if light arrives at an angle greater than:

• Critical angle

• Minimum angle

• Maximum angle

• Refraction angle

The main component in the structure of optical fiber that guides light is called:

• Cladding

• Core

• Jacket

• Buffer coating

The function of cladding in optical fiber is:

• To carry light signals

• To prevent signals from escaping the core

• To protect the cable from physical damage

• To absorb light signals

What is the main advantage of using single-mode fiber?

• Lower cost

• Can transmit long distances with minimal attenuation

• More flexible

• Can be used for household applications

Multi-mode cables are typically used for:

• Short-distance transmission

• Long-distance transmission

• Underwater transmission

• Satellite transmission
