    摘要： In an optical fiber ribbon 1 according to the present invention, four optical fibers 10, 20, 30 and 40 are arranged in parallel to each other in a plane, a part of the periphery of these four optical fibers is covered with a ribbon matrix 51, but no rest thereof is covered with the ribbon matrix. First areas covered with the ribbon matrix 51 and second areas uncovered with the ribbon matrix alternate with each other along the longitudinal direction thereof. Alternatively, the optical fiber ribbon 1 is covered with the ribbon matrix over its entire length. In the glass section of each optical fibers, the mode field diameter defined by the definition of Petermann-I at a wavelength of 1.55 μm is 8 μm or less, and the cable cutoff wavelength is 1.26 μm or less.

    摘要： In a split type ribbon optical fiber core cable capable of being split into cables, there are a plurality of ribbon optical fiber core cable units, each of which are constituted by a plurality of colored optical fiber core cables arranged in a row; a coating resin of an ultraviolet curable resin wholly coats the plurality of colored optical fiber core cables; and a bonding resin of an ultraviolet curable resin bonds the ribbon optical fiber core cable units arranged in a row. In this cable, an adhesion strength between the coating resin and the bonding resin is in the range of 1 to 100 g/cm. Further, the bonding resin after curing has a Young's modulus of from 5 to 100 kg/mm.sup.2. The bonding resin after curing has an elongation coefficient of from 5 to 80%.

    摘要： An optical fiber ribbon is manufactured under a condition where, assuming that the optical fiber ribbon has a thickness of 2d (mm), a guide roller has a diameter of 2R (mm), and a period of time till the optical fiber ribbon comes into contact with the guide roller after leaving an ultraviolet irradiation apparatus is t (ms), a relationship of d/�(R+d).times.t!

    摘要翻译： 在假设光纤带的厚度为2d（mm）的情况下，导辊的直径为2R（mm），直到光纤带进入的时间为止，制造光纤带 在离开紫外线照射装置之后与导向辊的接触为t（ms），满足d / [（R + d）×t] <0.2的关系。 因此，不会对光纤带产生损害，并且在其涂覆的光纤中不会发生微弯曲，从而可以防止传输特性恶化。
