Abstract
Disclosed is a non-steel high strength data transmission cable having a strength member (5) and a core (1). The high strength data transmission cable includes a length of a core-cable (10), the length of core-cable (10) includes core (1) plus at least. one. fiber-optic conductor (2) that is: (i) disposed in a helical shape; and (ii) completely encased in a solid, flexible material. Also disclosed is a process for making a high strength data transmission cable. The high strength data transmission cable is capable of being wound on a winch under tensions and surging shocks experienced by a fishing trawler, and provides high quality data signal transmission and resolution so as to permit use for transmitting data during fish trawl operation from high-resolution sonars used to monitor fish caught.

A data transmission cable having a strength member (5) preferably formed of synthetic fibers, and a core (1), the data transmission cable comprising a length of a core-cable (10), the length of core-cable (10) comprising core (1) as well as comprising at least. one fiber-optic conductor (2) that is:
- (i) disposed in a helical shape;
- and (ii) completely encased in a solid, flexible material.
A process for producing a data transmission cable, the process comprising steps of:
- (i) situating in spiraling helical fashion at least one fiber-optic conductor (2) about a core (1) comprising thermoplastic material forming the surface of core (1);
- (ii) next;
- situating additional the material (3) about the combination of the core (1) and the fiber-optic conductor (2) that is helically disposed about 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 layer (3) while not destroying the structural integrity of layer (3), while also to permit elongating and compacting said resultant cable and the strength member comprising said resultant cable;
- (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.
