1. Which of the following fiber-optic cable types can help data travel approximately 500 meters?
- multimode
- single-mode
Explanation: Multimode fiber has a shorter distance limitation than single-mode fiber. Commonly used on LANs with a distance of a few hundred meters but can be up to 2 km.
2. Which of the following fiber-optic cable types use light emitting diodes (LEDs) as a data light source transmitter?
- multimode
- single-mode
Explanation: Multimode fiber used LEDs as the light source.
3. Which of the following fiber-optic cable types use lasers in a single stream as a data light source transmitter?
- multimode
- single-mode
Explanation: Single-mode fiber uses laser technology as the light source.
4. Which of the following fiber-optic cable types is used to connect long-distance telephony and cable TV applications?
- multimode
- single-mode
Explanation: Single-mode fiber is commonly used for long haul TV and telephony applications.
5. Which of the following fiber-optic cable types can travel approximately 100 km?
- multimode
- single-mode
Explanation: Single-mode fiber is used for long haul applications up to 100 km.
6. Which of the following fiber-optic cable types is used within a campus network?
- multimode
