Abstract
The present disclosure provides a micro sheath buffer tube with rollable optical fiber ribbons for optical fiber cable to reduce the overall cable diameter. The buffer tube indicates one or more subunits, a micro sheath layer and a plurality of water swellable yarns. The one or more subunits encloses a plurality of optical fiber ribbons. Each optical fiber ribbon of the plurality of optical fiber ribbons includes 12 optical fibers. Further, each of a plurality of optical fibers is a colored optical fiber. In addition, the micro sheath layer surrounds the one or more subunits. Furthermore, the one or more subunits has a coating layer of low smoke zero halogen material.
Claims7
An optical fiber cable comprising:
- one or more flexible modules such that each module encloses a plurality of optical fiber ribbons, where each optical fiber ribbon is a rollable optical fiber ribbon, wherein each rollable optical fiber ribbon has a plurality of optical fibers such that adjacent optical fiber are bonded, where at least one pair of adjacent fibers are bonded intermittently along length of the adjacent fibers;
- wherein the one or more flexible modules have a young's modulus of <500 MPa,
- wherein each of the plurality of optical fibers has diameter in the range 180-200 micron
- wherein the one or more flexible modules is made of low smoke zero halogen material and an outer sheath layer surrounding the one or more flexible modules.
