摘要： PROBLEM TO BE SOLVED: To miniaturize a connector capable of connecting plural pairs of ferrules. SOLUTION: This optical fiber connector is obtd. by inserting an internal housing 5 having ferrule holding holes 7 penetrated therein into the through-hole 2 of an external housing 1, inserting a pair of the ferrules 21, 31 holding optical fibers 22, 32 into the ferrule holding holes 7 from both sides and holding both ferrule 21, 31 on the same axial line, thereby enabling the connection of the optical fibers to each other. The ferrules to be held are plural pairs. In such a case, the plural ferrule holding holes 7 are formed into the one internal housing 5 so that the paired ferrules 21, 31 can be inserted into the ferrule holding holes 7.

摘要： PURPOSE:To maintain the attenuation rate of light by multilayered films at a specified rate by providing an optical fiber with an even number of sheets of multilayered films in parallel with a plane slightly inclined from a plane perpendicular to the optical axis of this fiber in its mid-way and specifying the arrangement thereof. CONSTITUTION:The multilayered films 3, 10 of the same kind are arranged in a pair in parallel with the plane slightly inclined from the plane 4 perpendicular to the optical axis (a) in the mid-way of the light transmission path in the optical fiber 1 of one ferrule 2 embedded with the optical fiber 1 at its center by rotating these films at about 90 deg. with each other around the optical axis(a). In such a case, the multilayered films 3 of which the rotating direction is rotated counterclockwise are the multilayered films 10. The multilayered films 3 and the multilayered films 10 do not attain the state parallel with each other. The attenuation rates of the X direction and Y direction of the plane perpendicular to the optical axis (a) of the optical fiber 1 are complementarily attenuated with each other and are made constant even if there is a case that the plane of polarization of the incident light on the optical fiber 1 is rotated around the optical axis a by an external factor, according to such light transmission member.

摘要： PURPOSE:To finely adjust an attenuation quantity of light by providing the middle of the light transmission line of an optical fiber embedded in a ferrule with dielectric multilayered films and a metallic film 3 for attenuating a photodetecting level. CONSTITUTION:The ferrule 1 is provided with a slit 2 arriving at the transmission path (b) embedded with the optical fiber by lancing from the surface in the central part of the longitudinal direction thereof. An attenuation plate 5 formed to a sandwich structure by providing the metallic film 3 formed by depositing a chromium metal, etc., by evaporation on a glass plate with the dielectric multilayered films 4, 4 across the metallic film is inserted into the slit 2 and is fixed by an adhesive, etc., by which the ferrule 1 is formed. The light level at which the light is made incident by the dielectric multilayered films 4 is attenuated by a prescribed quantity and is further finely adjusted to the desired attenuation quantity by the metallic film 3. This light is transmitted to a photodetecting side. The light after attenuation to the prescribed quantity by the dielectric multilayered films 4 transmits the metallic film 3 and, therefore, the quantity of the heat absorbed in the metallic film is lowered and the metallic film does not oxide any more. The fluctuation in the attenuation quantity is thus prevented.
