Which mode of fiber cable has about one-fifth the diameter of the other mode?

Single-mode fiber has a much smaller core diameter compared to multimode fiber, making it approximately one-fifth the diameter. This design allows single-mode fiber to carry light directly down the fiber without bouncing off the core-cladding interface as much as multimode does, resulting in lower dispersion and enabling longer-distance data transmission. This characteristic is particularly advantageous for long-haul telecommunications and high-bandwidth applications, where maintaining signal integrity over vast distances is essential. The smaller core of single-mode fiber permits only one mode of light to propagate, which minimizes signal loss and allows for high-speed data transfer over long distances, unlike multimode fiber, which is better suited for shorter distances due to modal dispersion. The other cable types listed, such as plastic optical fiber and step-index fiber, either refer to different applications or types of multimode fibers and do not specifically indicate the highly focused transmission characteristics associated with single-mode fiber.
