In optical fiber communication (transmission) link, in order to achieve the different modules, the needs of theflexible connection between devices and systems, there must be a able to removable between optical fiber and optical fiber (activities) of the connection device, can make the light path according to the required transmission channel,with the purpose of the implementation and complete reservation or expectations and requirements, to achieve thefunction of the device is called a connector. Optical fiber connector is the fiber of two surface precision docking,so that the optical output of light energy to maximize the coupling to the receiving optical fiber, and optical link due to the intervention, and to minimize the impact of the system, it is the basic requirement of optical fiber connector. To a certain extent, optical fiber connector also affects the reliability and the performance of optical transmission system.
Optical fiber connector is one of the biggest light systems use optical passive components. To the requirement of the connector is mainly low insertion loss, high reflection loss and good repetition of plug, environmental stability and good mechanical properties, etc. Due to loss of optical fiber connector is also a kind of product, so it also requires its price is low. Its typical applications include communications, local area network (LAN), optical fiber to the home (FTTH), High quality video transmission, optical fiber sensing, testing instruments and meters, CATV, etc.
Here of optical fiber connector is exactly in optical fiber connector, is based on optical fiber connectors to classification of removable or not, so there is a sealed connector accordingly, called a fixed connector, not to mention here. Optical 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 media, such as plastic as the transmission medium, such as optical fiber connector; According to the connection head structure can be divided into: FC, SC, ST,LC, D4, DIN, MU, MT, etc. Various type; According to the optical fiber end face shape with FC, PC (including SPC or UPC) and APC type; According to the optical fiber some points and single core and multicore (such as MT – RJ) type optical fiber connector.
Optical fiber connector applications, a wide variety.
