1. A process for producing a data transmission cable, the process including steps of:
(i) situating in spiraling helical fashion at least one fiber-optic conductor (2) about a core (1) comprising thermoplastic material forming a surface of core (1);
(ii) next, situating additional thermoplastic material (3) about a combination of the core (1) and the at least one fiber-optic conductor (2) that is helically disposed about the core (1), so as to entirely encase the fiber-optic conductor within thermoplastic material;
(iii) next, permitting the thermoplastic materials to set, thereby forming a core-cable (10);
(iv) next, forming a flow shield (4) about the core-cable (10);
(v) next, forming a hollow braided strength member comprising synthetic material about the core-cable sheathed by the flow shield; followed by subjecting the resultant cable to tension and to heat sufficient to permit permanently deforming the thermoplastic material comprising a layer (3) while not destroying the structural integrity of the layer (3), while also to permit elongating and compacting said resultant cable and the strength member comprising said resultant cable; and
(vi) next, determining that a desired amount of elongation and compaction of the resultant cable and the strength member comprising said resultant cable has been achieved, followed by cooling the resultant cable to an ambient temperature while maintaining tension on the cable;
wherein the process further comprises the step of:
(vii) providing additional fixation between the core (1) and the at least one fiber-optic conductor (2) helically disposed about the core (1), the additional fixation being additional to a fixation that is obtained by helically disposing the at least one fiber-optic conductor (2) about the core (1), the additional fixation being provided prior to step (ii) so that the combination of the core (1) and the at least one fiber-optic conductor (2) that is helically disposed about the core (1) remains uncased prior to step (ii).
