The fiber optic patch cord can be divided into two types according to the work mode of the interface, it is simplex and duplex. Then what is simplex and duplex, how to use them? They are two kinds of communication channels in telecommunications and computer networking, which provide pathways to convey information.

What is simplex fiber patch cord?
Simplex is that data transmission only supports transmission in one direction. The two ends of communication, one end is the transmitter and the other end is the receiver, which is not reversible. For example, broadcasting stations usually only send signals to audience site, and do not receive signals from audience site.

What is duplex fiber patch cord?
Duplex is divided into half duplex and full duplex. Half-duplex can transmit data in both directions on the signal carrier, but not at the same time. In the communication process, the transmitter and receiver at both ends of the communication system can switch the direction through the receive/transmit switch to realize transmission in a single direction. It can also be said that the half-duplex mode is a simplex communication with switchable directions. . For example, on walkie-talkie, when you press the call button, you can send a conversation to the other party, and the other party can also hear it, but the other party cannot talk to you at the same time.

Full duplex is capable of two-way data transmission in both directions of the signal carrier at the same time. Receiving data while sending data, which requires the sending end and the receiving end to have independent receiving and sending capabilities at the same time. The full-duplex mode can also be seen as a simplex communication that allows two-way simultaneous transmission. Just like a telephone, both parties can talk at the same time by using two-way instant transmission technology. The duplex jumper can be composed of two simplex jumpers through a special design. For example, the Uniboot jumper uses a single tube and dual core.

Both simplex and duplex fiber jumpers can have single-mode and multi-mode modes. Single-mode and multi-mode have different applications. Generally speaking, single-mode is compared Suitable for long-distance transmission, and multi-mode is suitable for short-distance transmission. Choose which mode of fiber jumper depends on the actual applications.
