One of the most established and most normal types of media transmission frameworks utilized generally and in present day times is optical media transmission. Optical media transmission can be characterized as the utilization of light to send data. A portion of the more remarkable and recognizable instances of optical media transmission frameworks incorporate route lights, flares, semaphore correspondence and smoke signals. In spite of the fact that these non digital techniques for correspondence may appear to be out of date, they are in any case vital components of current framework. Fiber-optics and infrared sensors are likewise kinds of optical media transmission.
In the realm of media transmission, explicit specialized devices are frequently characterized by their status as either half-duplex or full-duplex. The essential contrast between these two types of correspondence is whether correspondence can happen at the same time between the two players. For instance, a full-duplex framework, for example, a cell gadget, permits people to connect with each other at the same time.
