An assembly for sealingly enclosing a space into which one or more optical fibres and/or optical cables is or are fed includes a container defining the space and a sealing member. The container has an opening therein. The sealing member sealingly encloses the one or more optical fibres and/or optical cables positionable distinctly and separately from the container. The sealing member: (a) can be placed in the opening so that the one or more optical fibres and/or optical cables extend through the opening into the container, and (b) can be heat and/or pressure sealed to the container to seal the opening around the one or more optical fibres and/or optical cables.

Optical fibre sealing assembly

A method is provided for sealing a container into which optical fibers are fed. A portion of the optical fibers is accommodated between two strips which are sealed together by applying heat and/or pressure. The strips are then placed in an opening of the container and the container is sealed. The strips, which may be made of plastic, support the fibers while providing an excellent seal.

Articles and methods are provided for enclosing an elongate substrate. A container is provided which is configured to receive the elongate substrate. A first polymeric sealing material having a first softening point and a first melt viscosity is positioned in the container. A second polymeric sealing material is positioned in the container between the first sealing material and an end of the container. The second sealing material has a second softening point lower than the first softening point and a second melt viscosity lower at a defined temperature than the fist melt viscosity.
