Fiber connector according to the different can be divided into common transmission medium of silicon-based single-mode and multimode optical fiber connectors, and other such as such as plastic optical fiber connector for transmission medium; According to the connection head structure can be divided into: FC, SC, ST, LC, D4, DIN, MU, MT, etc. Various forms.Among them, the ST connector is typically used for wiring devices, such as optical fiber distribution frame, fiber module, etc;The SC and MT connectors are normally used for network devices.According to the optical fiber end face shape with FC, PC (including SPC or UPC) and APC;According to the classification and single core and multicore of optical fiber some (such as MT – RJ).Widely used optical fiber connector, wide variety.In the process of practical application, we usually according to different to distinguish between the structure of the optical fiber connector.
