Name a type of fiber optic cable used for telecommunications applications.

The type of fiber optic cable that is primarily recognized for telecommunications applications is single-mode fiber optic cable. Single-mode fiber is designed to carry light directly down the fiber with minimal distortion, allowing for greater distances and higher bandwidth capacities compared to multi-mode fiber. Due to its efficiency in transmitting data over long distances, it is commonly used in telecommunications networks, especially for connecting telecommunication exchange points and for fiber-to-the-home (FTTH) installations.

Plastic fiber optic cable and armored fiber optic cable serve specific purposes but are not typically the standard in telecommunications. Plastic fiber is generally used for short-distance applications due to its higher attenuation and lower bandwidth capabilities. Armored fiber optic cable is designed for environments where physical protection is necessary, but it doesn’t play a primary role specifically in telecommunications; rather, it is used in scenarios where the cable may be exposed to damage. Stainless steel fiber optic cable does not exist in a standard form and would not be considered a common type of fiber optic cable for telecommunications.

Therefore, recognizing single-mode fiber optic cable as the correct answer aligns with its widespread use and importance in modern telecommunications infrastructure.
