What is the difference between simplex and duplex interfaces of optical fiber jumper?

When we first contact the optical fiber jumper, many children may not know what simplex and duplex mean? This article will explain what is simplex and duplex. In fact, simplex and duplex of optical fiber jumper refer to the working mode of interface, and simplex and duplex are the two modes of communication channel in telecommunication computer network.

Simplex refers to the transmission of information in one direction. At both ends of the communication, one end is the transmitter and the other end is the receiver. It is not reversible. Duplex can carry out two-way information transmission on the signal carrier, and receive data while sending data. The sending end and receiving end are required to have independent receiving and sending capabilities at the same time.

More simply, a simplex jumper has only one interface at both ends, while a duplex jumper has two interfaces at both ends. Duplex jumpers are usually used for various duplex communication applications, such as workstations, optical fiber switches and servers, optical fiber modems, etc.
