Abstract
An optical fiber cable of the present disclosure is formed by assembling a plurality of drop optical cables, and each of the drop optical cables has a structure where at least one or more optical fiber cores and a tension fiber or a tension member is embedded in a sheath such that the drop optical cable has two or more axes each having a minimum value of a second moment of area with respect to arbitrary neutral planes, and even an optical cable obtained by assembling drop optical cables has a structure having two or more axes each having a minimum value of the second moment of area with respect to arbitrary neutral planes.
Claims5
An optical fiber cable in which a plurality of drop optical cables are bundled, wherein each of the drop optical cables has, in a cross section perpendicular to a longitudinal direction thereof, two or more neutral planes minimalizing a second moment of area;
- and
- wherein 2N2−2N+1 (where N=1, 2, 3, . . . ) drop optical cables are arranged in a rhomboid shape on a cross section of the optical fiber cable, and each of the neutral planes of the plurality of drop optical cables is parallel to a diagonal line of the rhomboid shape.
