An Introduction To Simplex And Duplex Fiber Optic Cable
It is known to all that fiber optic cable is made of glass or plastic that mainly used for transmitting information. Fiber optic cable can be divided into many types according to different classification principles, such as source, mode, usages... In this text, we would mainly introduce simplex and duplex fiber optic cable as well as their differences. Simplex Fiber Optic Cable A simplex fiber only consists one single strand of glass of plastic fiber. Simplex signals are sent in one direction. It is much like what we said “one-way-street”. If a signal is transmitted from device A to device B over a simplex fiber optic cable, it cannot return from device B through the same cable. For example, we receive signals from radio station but never send signals to it. Thus, it is used for applications that only require one-way data transfer. Simplex fiber is most often used where only a single transmit and receiver line is required between devices or when as multiplex data signal is used....
