Single-Mode Fiber-Optic Cable Features

AC.

The correct answers are A and B.

Single-mode fiber-optic cable:

A. consists of a single strand of glass fiber: Single-mode fiber-optic cable consists of a single strand of glass fiber that is 8.3 to 10 microns in diameter. This is much smaller than the diameter of a human hair. Because it only has one pathway for the light to travel, it can transmit data over longer distances with less signal loss than multimode fiber.

B. has higher attenuation than multimode fiber: Attenuation is the loss of signal strength as the signal travels over a distance. Single-mode fiber-optic cable has higher attenuation than multimode fiber. However, because it can transmit data over longer distances with less signal loss, it is often used for long-haul transmissions in telecommunications and other industries where data needs to be transmitted over great distances.

C. carries a higher bandwidth than multimode fiber: This statement is incorrect. Multimode fiber typically has a higher bandwidth than single-mode fiber. This is because multimode fiber has a larger core diameter, allowing more light to be transmitted at once. Single-mode fiber has a smaller core diameter, so it can transmit less light at once.

D. costs less than multimode fiber: This statement is incorrect. Single-mode fiber-optic cable is typically more expensive than multimode fiber because it requires more precise manufacturing and installation techniques.

E. operates over a shorter distance than multimode fiber: This statement is incorrect. Single-mode fiber-optic cable can transmit data over longer distances with less signal loss than multimode fiber. It is often used for long-haul transmissions in telecommunications and other industries where data needs to be transmitted over great distances.
