摘要： A ferrule for optical connector according to the present invention is provided with a fiber positioning hole, a pair of guide holes into which guide pins are inserted, and a connecting end face in which ends of the fiber positioning hole and guide holes open. A chamfer portion equivalent to a part of a surface of a body of revolution is formed at each guide hole on the connecting end face side. Further, the connecting end face is formed at an angle relative to a plane normal to the center axes of the pair of guide holes. In this structure, the slope of the connecting end face can suppress degradation of connection loss, and the provision of the chamfer portions can facilitate insertion of the guide pins, prevent damage of the connecting end face due to the guide pins, and also suppress degradation of connection loss due to the damage.

摘要： A pair of guide holes for guide pin insertion and one or a plurality of optical fiber positioning holes extending inwardly from the front end surface are formed in a connector ferrule of an optical connector. A chamfer is formed on the opening edge portion of the guide hole of the connector ferrule on the front end surface side thereof. The opening diameter R of the guide hole at the front end surface is preferably 1.0 to 1.5 mm when the front end surface is slant polished at an angle of 8 degrees. Furthermore, the chamfering angle θ of the chamfer is preferably 90 to 150 degrees. Moreover, the average particle size of the filler contained in the connector ferrule is no more than 20 μm. As a result, the surface of the chamfer is comparatively smooth.

摘要： An optical fiber suitable for use in a single fiber or multifiber optical connector or array is structured with a core region and a cladding region surrounding the core region, and exhibits a bending loss of a fundamental mode of the fiber at a wavelength λ is lower than 0.1 dB/m at a diameter of 15 mm, a mode-field diameter of the fundamental mode at an end of the fiber at the wavelength λ is between 8.0 μm and 50 λ, and a bending loss of a first higher-order mode at the wavelength λ is higher than 1 dB/m at a diameter of 30 mm. The fiber may be multistructured, wherein the cladding region comprises a main medium and a plurality of sub medium regions therein to form a spatially uniform average refractive index.
