摘要： A spacer having a high-tensile member at the center thereof has grooves extending helically. Coated optical fibers have been disposed in each groove. This assembly is covered with a wound covering and further with a sheath. The proportion of the total sectional area of the coated optical fibers to the sectional area of each groove, i.e., the degree of packing, is regulated to 10 to 50%.

摘要： The invention is to provide an optical fiber cable in which an end of an optical fiber core is prevented from being dragged inside the main cable body part upon the application of a tension on the optical fiber cable, and which prevents the increase in transmission loss and breakage of the optical fiber core caused by the movement of the optical fiber core near the connection point. The invention can be characterized in that an optical fiber cable is formed in such a manner that yarns are stranded in a periphery of the stack of the optical fiber ribbons, and an outer sheath of the main cable body part is formed with a tension member united thereto on the periphery of the yarns.

摘要： An optical fiber cable in which optical fiber ribbon stack can be accommodated in a cylindrical space efficiently and which has excellent loss characteristic. A plurality of optical fiber ribbons 1 are stacked. Cushioning fillers 2 are disposed around the optical fiber ribbon stack 1. The optical fiber ribbon stack 1 and the cushioning fillers 2 are accommodated in a cylindrical member 3. The space factor of the cushioning fillers in the inner space of the cylindrical member as a remainder after removal of the optical fiber ribbon stack from the inner space is from 10 to 60%. Consequently, the optical fiber cable becomes excellent both in initial transmission loss and in loss increasing characteristic at a low temperature.

摘要： An optical fiber preform comprises a central core portion having a maximal value Nc of refractive index in the center, and outside the central core portion, comprising at least a depressed portion having a minimal value Nd of refractive index, a ring portion having a maximal value Nr of refractive index and an outside cladding layer having a maximal value No of refractive index. The optical fiber preform satisfies a relation of Nc≧Nr>No>Nd among the values of refractive index. A method of the optical fiber preform comprises fabricating a glass rod by inserting a rod containing at least the central core portion into a pipe containing at least the depressed portion and integrating them, fabricating a glass pipe having the ring portion, and fabricating a vitreous body by integrating the glass rod and the glass pipe by collapsing after inserting the glass rod into the glass pipe.
