Fiber optic connector is a removable (active) connection between fiber and fiber optic device, it is the fiber's two ends of the precision docking, so that the optical energy emitted by the fiber can be maximized coupling into the receiving fiber, and because of its involvement in the optical link and minimize the impact on the system, which is the basic requirements of fiber optic connectors. To a certain extent, fiber optic connectors also affect the reliability and performance of optical transmission systems.
Fiber optic connectors according to the transmission medium can be divided into common silicon-based fiber single-mode, multi-mode connectors, as well as other such as plastic as the transmission medium of fiber optic connectors; According to the connection head structure form can be divided into: FC, SC, ST, LC, D4, DIN, MU, MT and so on. Among them, ST connectors are commonly used in wiring equipment, such as fiber optic wiring racks, fiber optic modules, etc. SC and MT connectors are typically used on the network device side. FC, PC (including SPC or UPC) and APC by fiber end face shape; There are also single-core and multi-core (e.g. MT-RJ) points by the number of fiber cores. Fiber optic connectors are widely used in a wide variety of applications.
An RF coaxial connector (RF connector) is often referred to as a component mounted on a cable or mounted on an instrument as an electrical connection or separation element of the transmission line. It belongs to the mechatronics product. Simply put, it mainly acts as a bridge.
Rf connectors have a short history compared to other electronic components. The UHF connector, which appeared in 1930, was the first RF connector. During World War II, due to the urgent need of war, with the development of radar, radio and microwave communications, N, C, BNC, TNC, and other medium-sized series, after 1958, SMA, SMB, SMC and other miniaturized products, in 1964 developed the United States military standard MIL-C-39012 "RF coaxial connector general specification", from then on, RF connectors began to standardize, serialization, generalization direction.
