Many compaines make large investment on manufactureing and R&D of fiber optic connectors. On the contrary, optical fiber splice is nearly ignored. In China,there are only two manufactures that professionally provide optical fiber splice, Winstar Technologies and JiangSu UNIKIT Optical Technologies. Both of them claim top in this filed. "In fact, the optical fiber splice is not a new product, some big companies have more than 10-year history of studying on this product ,such as 3M, Corning and Fujikura. It was first widely adopted in Japan, Europe and America. While China's FTTH market starts rapidly and in large scale, I believe there is broader market space for this product in the future. "said spokeman from Winstar Technologies. As the first manufacturer of fiber splice in mainland China, Winstar Technologies helds its own patented V-groove technology (fiber array substrate, patent No. ZL 2008 2 0001449X), their V-groove cutting technology provides them a high-quality performance. Average insertion loss of Per 1,000 optical fiber splice is betweent 0.06 to 0.07db, with an average return loss of more than 50dB. According to Genliang Lv,the general manager of another splice manufacture, JiangSu UNIKIT Optical Technologies, "We have launched three product of splice for 0.25mm fiber,0.9mm fiber and drop cable respectively with average loss less than 0.1dB,average return loss more than 40dB,and tensile strength reaching 2N. What plays a important role in the core of splice product is a joint of pre-fiber and matching fluid in the V-groove. While UNIKIT's splice is designed to have a reserve room for matching fluid separately,in order to effectively reduce the loss of matching fluid and ensure 20-year using life. It specially adapts to hard environment for its waterproof and dust-proof structure." In 2008, UNIKIT and Sunsea,Putian, Ningbo spring, TLC certification center jointly drafted the related standards of "mechanical connecter of single core fiber for telecom" based on fiber to the home (FTTH) architecture and general requirements. UNIKIT also upload a video of splicing process on YOUKU, the whole process only takes 15 seconds.
