Abstract
The present invention relates to an optical fiber cable (400, 500) with flexible wrapping tubes comprising a plurality of unit bundles packed in the optical fiber cable (400, 500), where each unit bundle has a plurality of optical fibers (106) enveloped by a non-extruded film (100), and at least one of the unit bundles takes a non-circular shape in a packed configuration and a sheath (404, 504) enveloping the plurality of unit bundles. Each unit bundle is formed by wrapping the non-extruded film (100) around the optical fibers (106) such that width edges of the non-extruded film (100) overlap along the length of the optical fiber cable (400, 500). Alternatively, the non-extruded film (100) is wrapped around the plurality of optical fibers (106) helically.
