Fiber media converters are specialized devices that convert electrical signals (from copper cables, such as Ethernet) to optical signals (for fiber optic cables) and vice versa. This conversion allows for the integration of fiber optic cabling into existing copper-based networks, extending transmission distances, and providing other advantages inherent to fiber optics.
