A spoolable device including a first communication interface, a second communication interface, a power management module, a functional electrical module, and a junction joining each of the above elements together and creating a shared pressure chamber. A method for making a spoolable device comprising welding a functional electrical module to a first portion of a junction box, welding a first communication interface to the first portion of a junction box, welding a power management module to a second portion of a junction box, welding a second communication interface to the second portion of a junction box, and welding the first portion of a junction box to the second portion of the junction box to form a pressure chamber inside the first and second portions of the junction box.

A tearable core, adapted for winding a sheet product, includes a cylindrical body wall defining a longitudinal hole of longitudinal axis XX′. The cylindrical body wall is tearable from an edge, and includes an outer strip and an inner strip that are helically wound on one another and displacedly overlapped in a lateral direction parallel to the longitudinal axis XX′, and secured together through their mutually facing surfaces by a first region of attachment. The strips are made of the material having characteristics such that the inner strip and the outer strip are made of cardboard having different water drops. The cylindrical body wall is formed by securing together the outer strip, a first end part of the outer strip of one turn being superposed and secured to a second end part of the outer strip of an adjacent turn through their mutually facing surfaces by a second region of attachment.

A conductor spool with a frame is provided with a plurality of first fingers, the first fingers and the frame defining a first spool surface. The frame is provided with an entry slot and an exit slot, a retainer gasket coupled to the frame proximate each of the entry slot and the exit slot. A cover is seated upon the frame, the cover enclosing the first spool surface. The conductor spool may be included in a wire harness and conductor spool assembly, the conductor spool seated upon a conductor lead furcated from a composite cable including at least one optical and at least one electrical conductor.
