The survey of ElectroniCast shows that in 2011 multi-mode fiber optic connectors dominate the global market, accounting for 60% market share, followed by single-mode fiber optic connectors, accounting for 34%; last is mechanical splice head which accounted for 6%.lectroniCast expected with the increase in data rate and link length, the use of single-mode fiber optic connectors is increasing rapidly, and telecommunications applications occupy the dominant position of the global single-mode fiber connector consumption. From 2012 to 2015, the global multi-mode fiber connector sales will continue to grow. Multimode fiber is best suited for short distance applications, such as the use of local area network, data centers and storage area network. The consumer market of mechanical splice head is also expected to continue to grow.Based on Data of Tiancheng consultants, in the next three or four years, the annual compound growth rate of global fiber optic connector market scale will reach 9.2 percent. China is expected to become the market of fastest growing and largest capacity in global optical connectors. In the next four or five years, the compound annual growth rate of Chinese market is 10.57%, it is estimated that China's market capacity will reach 6.79 billion yuan in 2016.
