A media converter is a device used in networking to connect two different types of media, such as copper and fiber optic cables. It converts the signal from one format to another, allowing network devices that use different transmission media to communicate with each other. Media converters are commonly used to extend network distances and upgrade networks from copper-based to fiber-based systems without replacing existing infrastructure. Key Functions of a Media Converter: Media Conversion: Media converters convert signals between different transmission media, such as: Copper (Ethernet) to Fiber: Commonly used in situations where copper cabling has limited distance or bandwidth. Fiber to Copper: Used when connecting fiber optic networks to copper-based devices like switches or routers.
