Abstract (en)
[origin: WO2021168136A1] Blocking of water and gas from an interior of the cable from passing into a closure includes applying blocking material to an end cut of the jacket, wherein the blocking device includes a film and a clamp to create a pocket for receiving the blocking material. A further blocking device is positioned over the window cut wherein the optical fibers are expanded relative to the jacket by pushing the jacket ends toward one another and rotating relative to one another. The blocking material surrounds both ends of the jacket and the bowed outward optical fibers. A further blocking device includes a tube, two end caps, and two clamps for creating a pocket over a window cut which receives blocking material. Rollable ribbon cable is disclosed.
