Fiber-Optic Cables Quiz

What is the main benefit of fiber-optic cables?

• High signal attenuation

• High information-carrying capability

• Low cost

• Susceptible to interference

Which is the typical diameter range of the core in Single-Mode Fiber (SMF)?

• 2 to 15 microns

• 80 to 100 microns

• 50 to 62.5 microns

• 150 to 200 microns

Which connector is commonly used in MMF & SMF gigabit Ethernet networks? Square connector that uses a push-pull connector similar to A/V equipment.

• Mech. Transfer Register Jack (MTRJ)

• Straight Tip (ST)

• Lucent Connector (LC)

• Subscriber Connector (SC)

What is the primary use of fiber-optic communication systems?

• Internet backbone

• Cable TV systems

• Data centers

What is the main disadvantage of fiber-optic cable?

• Large size

• Ease of handling

• Shorter distances

• High cost

There are two basic types of index profiles:

• Graded index

• Uniform refractive index

• Nonuniform refractive index

• Step index

Which type of fiber cable has a central core with a uniform refractive index and an outside cladding with a uniform refractive index?

• Single-mode step-index

• Multimode step-index

• Single-mode graded index

• Multimode graded index

What is the main advantage of multimode step-index fiber?

• Less modal dispersion

• Minimum dispersion

• High information transmission rates

• Easier to couple light into and out

In which type of fiber cable do light rays propagate through refraction rather than reflection?

• Multimode graded index

• Single-mode graded index

• Multimode step-index

• Single-mode step-index

What is the core diameter range of Multimode Graded Index fiber cables?

• 2 to 15 microns

• 50 to 62.5 microns

• 50 to 100 microns

• 8 to 10 microns
