Abstract
An optical fiber array is an optical communication device that consists of multi-core optical fibers and a V-grooved substrate. Due to the use of DWDM systems, the demand for optical fiber arrays has increased significantly. In this research, for the mass production of optical fiber arrays, we considered and proposed technology that automates the insertion of fiber into the V-groove. For automatic assemble of optical fiber array, a fiber must be put a precise position of V-groove. It is dependent on the friction coefficient of a optical fiber with the V-groove's slope whether precise positioning can be performed. A friction coefficient of a optical fiber and the V-groove's slope influences the positioning greatly. It is necessary to develop the measurement method of friction coefficient for assemble of optical fiber array. This paper deals with the equipment measuring coefficient of friction easily, and the relation of a friction coefficient and grinding processing of V-groove was obtained.
