  • OPTICAL FIBER CABLES WITH POLYETHYLENE BINDER
    Publication number: 20150153529
    Abstract: An optical fiber cable includes a bundle of a plurality of loose tubes held by a polyethylene binder. The polyethylene binder softens or melts when a hot cable sheath is applied during the cable manufacturing process. This prevents the polyethylene binder to cut into the loose tubes to cause indentations. Therefore, the resulting optical fiber cable is substantially free from indentations.
