What equipment is used to convert fiber optic cable to fiber optic cable
Fiber media converters are networking devices capable of connecting two different media types. In most cases, they are used to connect twisted pair or coaxial cable to a fiber-optic cable, allowing the interconnection of fiber-optic networks and cable systems with copper-based. Fiber Optic Converters (also known as Media Converters) are devices that convert the electrical signal used in copper wiring such as Ethernet or Serial Data into light waves for transmission over fiber optic cable. These devices are essential when you need to bridge fiber optic cables with Ethernet cables, especially in long-distance or high-speed network setups.
