With the rapid development of large-bandwidth and ultra-high-speed optical fiber communication technology, the requirements for future communication transmission quality are becoming more and more stringent. The optical fiber connector, which is widely used to realize one of the optical passive components of the two optitap connectors in the optical fiber communication system, is also facing the test of stricter technical indicators.
The optitap connector is widely used in optical communication systems, optical information processing systems, and optical instruments. It is often used to realize optical coupling from light sources to optical fibers, from optical fibers to optical fibers, and between optical fibers and detectors, especially in optical communication In the system, the optical fiber connector is the most used optical passive device. The International Telecommunication Union (ITU) defines a fiber optic connector as "a passive component used to stably, but not permanently, connect two or more optical fibers".
The main purpose of optitap connector is to realize the connection of optical fiber. 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.
In this method, the optical fiber is inserted and fixed in the ferrule, and after the surface of the ferrule is polished, alignment is achieved in the coupling tube. The outer components of the pins are made of metal or non-metal materials. The butt end of the ferrule must be ground, and the other end usually uses a bend limiting member to support the fiber or fiber optic cable to relieve stress. The coupling tube is generally made of two-half synthetic and fastened cylindrical members made of ceramic, or bronze, etc., and is mostly equipped with a metal or plastic flange to facilitate the installation and fixation of the optitap connector. In order to align the fibers as precisely as possible, the processing precision of the pins and coupling tubes is very high.
