Multimode Fiber (MMF)

Multimode fiber (MMF) is a type of optical fiber that carries multiple light signals simultaneously through its core, which is thicker than single-mode fiber. It uses a broader light path, allowing several modes (or channels) of light to travel at different angles. This makes MMF suitable for short to medium-distance data transmission, such as within buildings or campuses. It's generally easier and less expensive to install than single-mode fiber, but it has higher signal loss and bandwidth limitations over long distances. MMF is commonly used for high-speed Ethernet connections and data centers.
