Single-mode optical modules are best for long distances and fast speeds. They use a thin fiber core. This saves space and money. Dual fiber modules use two fibers. They are easier to set up and give steady communication. They use a thin fiber. Single-mode fiber uses a 9/125 µm core/cladding structure that supports only one propagation mode, which minimizes modal dispersion and allows signals to travel tens of kilometers with low attenuation. Multimode fibers have larger cores (typically 50/125 µm or 62. 5/125 µm) and support multiple. o In optical modules, "core" refers to the light-transmitting channel in the fiber.
