multimódus

Multimódus refers to a system or technology that utilizes or transmits information through multiple distinct modes or channels simultaneously. In the context of optical fibers, multimode fiber (MMF) is a type of optical fiber that can propagate multiple light modes. This is in contrast to single-mode fiber, which can only propagate one mode. The larger core diameter of multimode fiber allows for more light to be transmitted, making it easier to couple light into and connect. However, the presence of multiple modes leads to modal dispersion, where different light paths travel at different speeds, causing signal distortion over longer distances. Multimode fiber is commonly used for shorter-distance applications, such as within buildings or data centers, due to its cost-effectiveness and ease of use compared to single-mode fiber. Different types of multimode fiber exist, categorized by their bandwidth and performance characteristics, such as OM1, OM2, OM3, OM4, and OM5. Each category offers improved performance over the previous one, allowing for higher data rates and longer transmission distances within the multimode domain. The choice of multimode fiber depends on the specific application requirements, including distance, data rate, and budget.
