摘要:
In the connection of the optical fiber wires, it is required to align each axis of two optical passages to be connected, to minimize the connection space, and to include a retaining mechanism capable of preventing any invasion of foreign materials, such as dust, vapor and water. A pair of ferrule holders 2 for retaining a pair of optical fiber wires 21 positioned opposed to each other through an adapter B are rotated simultaneously by rotating an outer ring 4 to correct the displacement of the axes of the optical fiber wires. Further, a rotating stopper portion 33 on the shaft of the ferrule holder 2 is moved in conjunction with an elastic rotating stopper plate 13 disposed at the adapter B to retain the corrected position. A silicone low crosslinking-density gel 41 having the refractive index substantially equal to that of the optical fiber wires 21 is filled in a connection space 32, to minimize the connection space 32. The function of the silicone low crosslinking-density gel 41 can cope with any variance of external environment to retain the junction of the optical fiber wires 21 and prevent any deterioration of optical transmittance.
