Single-mode fiber is designed with a narrow core that allows light to enter at a single angle, reducing reflection and enabling it to carry signals over long distances without significant attenuation. This characteristic makes it the preferred choice for long-distance data transmission. Multimode fiber, on the other hand, has a wider core that allows light to enter at multiple angles, leading to more dispersion and making it more suitable for short distance transmission. Plastic optical fiber is generally used for very short-range connections and has a much lower bandwidth compared to glass fibers. Coaxial cable uses copper conductors and is not a type of fiber cable at all.
