Fiber patch cables can be classified into simplex and duplex according to the interface working mode. Simplex and duplex are two modes of communication channels in telecommunications and computer networks.
What is Simplex
Simplex means that the transmission of data is in only one direction. At both ends of communication, one end is the transmitter and the other end the receiver - they are not reversible. Radio stations, for example, usually only send signals to the audience, but do not receive signals from the audience.
What is Duplex
Duplex is divided into half duplex and full duplex. In half duplex, data can be transmitted in both directions on the signal carrier, but not simultaneously. In the communication process, the transmitter and receiver at both ends of the communication system can switch the direction through the receiving/sending switch, so as to realize the transmission in a single direction. It can also be said that the half-duplex mode is a simplex communication that can switch directions. For example, on a walkie-talkie, when you press the call button, you can send a conversation to the other party. The other party can also hear the conversation, but cannot talk with you at the same time.
