What is a Optical converter?

An optical converter, also called an optical media converter, is a device that converts electrical signals to optical signals and optical signals to electrical signals. In communication using metal cables such as LAN cables, the potential difference is transmitted as an electrical signal, but as the transmission distance increases, the electrical signal attenuates, and the electromagnetic noise generated inside and outside the cable makes communication errors more likely. In communication using optical fibers, flashing lights are transmitted as signals. Optical signals in optical fibers have a low attenuation rate and are not affected by electromagnetic waves, so by sandwiching a long optical fiber between two metal cables, stable long-distance communication can be achieved. At this time, the optical converter connects the metal cable and the optical fiber.
