Optical fiber jumpers can be divided into simplex and duplex according to the working mode of the interface. What are simplex and duplex? Simplex and duplex are two modes of communication channels in telecommunications and computer networks. Simplex and duplex jumpers can also be called single-link and duplex (single-core, dual-core).

1. What is a simplex fiber optic patch cord?

Simplex is data transfer only supported in one direction. At both ends of the communication, one end is the transmitter and the other end is the receiver, which is not reversible. A radio station, for example, usually only sends a signal to the audience and does not receive the audience's signal.

2. What is a duplex fiber optic patch cord?

A duplex is divided into half duplex and full duplex. Half-duplex means that data can be transmitted in both directions on the signal carrier, but not at the same time. During the communication process, the transmitter and receiver at both ends of the communication system can switch the direction through the transceiver/transmit switch to realize transmission in a single direction. It can also be said that the half-duplex mode is a simple communication with switchable directions.

For example, with a walkie-talkie, when you press the call button, you can send a conversation to the other party, and the other party can hear it, but the other party cannot talk to you at the same time.

Full-duplex is capable of bidirectional data transmission in both directions of the signal carrier at the same time, receiving data while sending data, requiring both the sender and the receiver to have independent receiving and sending capabilities at the same time.

The full-duplex mode can also be viewed as simplex communication that allows simultaneous transmission in both directions. Just like a telephone, the two parties can talk at the same time by using the two-way instant transmission technology. The duplex fiber jumper can be composed of two simplex jumpers through a special design. The fiber jumper is a single-tube dual-core.

Whether it is simplex or duplex fiber optic patch cord can have single-mode and multi-mode modes. Single-mode and multi-mode have different applications. Generally speaking, single-mode is compared with It is suitable for long-distance transmission, and multi-mode is suitable for short-distance transmission. The choice of which mode of fiber jumper is based on the actual application scenario.

T&S Communications is one of the leading manufacturers of optical communication components in China, focusing on developing, manufacturing, and marketing a wide range of optical communication products ranging from passive to active categories of optical communication networks and data centers.

How to Define the Three Value Standards of the End Face of the Patchcord?

The two end faces of the fiber must be precisely butted so that the light energy output by the transmitting fiber can be coupled to the receiving fiber to the maximum extent. The successful connection of optical fiber lines depends on the quality of the physical connection of the optical fibers.

Classification and Instruction for Use of Fiber Optic Patch Cord

Fiber optic patch cord refers to connector plugs installed at both ends of the optical cable to realize the active connection of the optical path； One end with a plug is called a pigtail. Fiber optic patch cords are similar to coaxial cables, except that there is no mesh shield. The center is the glass core of light propagation.
