PURPOSE:To prevent an optical fiber from coming off a groove during the connecting work of the fiber so as to improve the working property, by applying an optical fiber inlaying method, and restraining the movement of the optical fibers in directions other than the longitudinal direction of the base plate. CONSTITUTION:An optical fiber strand section inlaying groove 8 and optical fiber coating section inlaying groove 9 are respectively provided in an optical fiber strand section base plate 6 and optical fiber coating section base plate 7. Cross sections of the grooves 8 and 9 have inverted OMEGA shapes and shoulder sections 8a and 9a are respectively formed to the grooves 8 and 9 in the longitudinal direction of the grooves. V-shaped grooves 10 are formed on both sides of the grooves 8 and 9 so as to reduce the rigidity of the side walls 8b and 9b of the grooves 8 and 9. Since the shoulder sections 8a and provided to the groove 8 so that optical fibers cannot move in directions other than the longitudinal direction, the optical fibers do not come off the groove 8 and, accordingly, no keeping plate is required when the optical fibers are put together and joined. Therefore, the working property of this optical fiber joining work is higher than that of conventional joining work using a V-groove base plate. |
