Optical fiber connector, commonly known as the union, International Telecommunications Union ( ITU ) is suggested to be defined as "to stably, but not permanently connected to two or more optical fiber passive component". Mainly used for the realization of system equipment, equipment and instruments, equipment and optical fiber and optical fiber and optical fiber by a permanent fixed connection, optical fiber communication system in an passive devices. It is due to use of the connector, such that the light path between the detachable connection is possible, so as to provide a convenient entrance test of optical fiber, the optical system for the measurement and maintenance; and for network management provides a medium, the optical system switching scheduling more flexible.

Optical fiber is mainly used as a transmit digital data, and radio frequency coaxial cable is used for transmitting analog electronic data. Digital data must be adjusted for the analog signal to the base station and mobile phone transmission between, therefore, RF coaxial cable for mobile communication system is indispensable. Installation and maintenance of optical fiber use facility cost is relatively high, and the use of radio frequency coaxial cable facility cost is relatively low. With the increasing number of Chinese3G users and 3G service continued to expand, the expected number of future China 3G network construction will accelerate development, brought huge demand for RF coaxial cable. The global3G mobile communications network using coaxial cable market size in 2010reached 15900000000 yuan, is expected in 2014 the global3G market of mobile communication radio frequency coaxial cable demand will reach 1500000km.

In the country "12th Five-Year Plan", national broadband network infrastructure investment will total1.6 yuan, of which 570000000000 yuan investment in broadband access network. Affected by the policy, based on optical fiber network infrastructure of future importance and value, the operator optical communication investment may be substantially exceed market expectations, especially optical transmission and fiber optic input.

China optical fiber inside five years will become the world's largest supplier of optical fiber connector. In 2011China optical fiber connector is composed of 9000000 sets of production capacity increased to12000000, it will be soft cable capacity increased from 13000 km to 130000 km, and the preliminary plan in 2012 will further increase the capacity of optical fiber connector50% to18000000 sets of production capacity to meet the market demand for optical fiber connector.3G, networking, intelligent application of optical communication, promote the development of the whole industry chain leap, they drove the system equipment, devices, electronic components industry new development, it also breeds the new generation of products into our life.
