Fiber optic patch cords can be divided into simplex and duplex according to the working mode of the interface, so what is simplex and duplex? Simplex and duplex are two modes of communication channels in telecommunication and computer networks, simplex and duplex patch cords can also be called simplex and duplex (single-core and dual-core).
What is simplex?
Simplex is a data transmission that supports transmission in only one direction. The two ends of the communication, one end is the transmitter and the other end is the receiver, do not have reversibility. Radio stations, for example, usually only send signals to the audience and do not receive signals from the audience.
What is duplexing?
Duplex is also divided into half-duplex and full-duplex. Half-duplex is the ability to 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 achieve transmission in a single direction, and it can also be said that half-duplex mode is a switchable direction of simplex communication. For example, when you press the call button, you can send a conversation to the other party, the other party can also hear, but the other party can not talk to you at the same time.
Full-duplex is the ability to transmit data in both directions of the signal carrier simultaneously in both directions, receiving data while sending data, requiring independent receive and send capabilities on both the transmitter and receiver sides. Full duplex mode can also be thought of as simplex communication that allows simultaneous transmission in both directions. Just like a telephone call, both sides can talk at the same time is the use of two-way instant transmission technology. A duplex patch cord can be composed of two simplex patch cords through a special design, like the Uniboot patch cord that uses a single tube with two cores.
Whether simplex or duplex fiber optic patch cords can have single-mode, multimode mode, click here to learn what is single-mode, multimode, single-mode and multimode have different applications, generally speaking, single-mode is more suitable for long-distance transmission, multimode for short-distance transmission. Choose which mode of fiber optic patch cord to the actual application scenario.
