1. The optical fiber quick connector is a very innovative field-terminated connector that contains factory-installed optical fibers, pre-polished ceramic ferrules, and a mechanical splicing mechanism.

At present, with the continuous development of the domestic communication industry, optical fiber communication has entered the stage of practical application, and the scope of application is getting wider and wider. For optical fiber connectors used in optical communication systems in my country, either imported connectors are used, or so-called "parts" such as imported ceramic sleeves and peripheral metal parts are assembled in China, or according to the imported foreign technology and Key equipment is produced, mainly FC-type fiber optic connectors. In view of this situation, the author recommends the following.

The performance of the optical fiber connector, first of all, the optical performance, in addition to the interchangeability, repeatability, tensile strength, temperature and insertion and removal times of the optical fiber connector.

The main purpose of fiber optic connectors is to connect optical fibers. Optical fiber connectors, which have been widely used in optical fiber communication systems, have many types and different structures. But on closer inspection, the basic structure of various types of fiber optic connectors is the same, that is, most fiber optic connectors are generally realized by high-precision components (composed of two pins and a coupling tube). Alignment of optical fibers.

Optical fiber connectors can be divided into common single-mode and multi-mode connectors of silicon based optical fiber according to different transmission media, as well as other optical fiber connectors using plastic as transmission media; According to the connector structure, it can be divided into FC, SC, ST, LC, D4, DIN, MU, MT, etc.

The manufacturing of precision metal parts is the basis for the production and manufacturing of various precision instruments and equipment, and its development is closely related to a country's scientific and technological level and manufacturing development. In the early stage, the manufacturing industry of precision metal parts was monopolized by developed industrial countries such as Europe, America and Japan. Most Chinese manufacturing enterprises were in the stage of outsourcing processing and learning of non core products.

From the appearance, the "jumper" of the board card in the computer is a small metal rod (jumper pole) embedded in the motherboard, sound card, hard disk and other devices, and a small clip (jumper clip) sheathed on these metal rods. The function of the jumper is to adjust the on-off relationship of different electrical signals on the equipment, and to adjust the working state of the equipment, such as determining the motherboard voltage, the master-slave relationship of the driver, and so on.

The difference between ordinary patch cords and cross-connect cords is compared. Ordinary jumper (straight-through cable): used to connect different devices, such as the connection between the computer network card and the module, the connection between the patch panel and the wiring room, and the connection between the patch panel and the HUB or switch. The RJ45 connectors at both ends of the straight-through cable are wired in the same way, using the T568B standard line sequence.

For jumpers, an important performance is the performance problem when bending. Since UTP twisted pairs are generally solid cores, they are poor in manageable performance. First, the cable is relatively hard, which is not conducive to bending. Second, the solid core cable will have obvious return loss when it is bent, which will cause the performance of the cable to decline. Therefore, the solid core cable generally has a bending radius of clear requirements. For flexible cables with multi-strand cores specially used to manage jumpers, these problems are not present.
