A 100M MM to SM Media Converter is designed to convert 100Mbps multimode fiber (MMF) signals to single-mode fiber (SMF) signals. It acts as a bridge between different types of fiber, allowing devices using multimode fiber to connect to a single-mode fiber network and achieve longer transmission distances. This converter is typically used in scenarios where signal conversion is needed between short-distance multimode fiber equipment and long-distance single-mode fiber networks, such as in data centers, enterprise networks, and wide-area networks (WANs).
