A hybrid cable for collecting data inside a well includes an electrical cable extending along a longitudinal axis of the hybrid cable, an optical fiber extending along the longitudinal axis, an armor that extends along the longitudinal axis, and encircles the electrical cable and the optical fiber, and a connecting device extending along the longitudinal axis, to enclose the electrical cable and the optical fiber, and to be enclosed by the armor. The connecting device has an unsmooth external surface.

An apparatus includes a rigid housing, a first connector coupled to the housing, the first connector to receive an edge connector of an input/output (I/O) device, and a second connector coupled to the housing, the second connector to couple to an edge connector socket. Pairs of electrical connection pins of the first connector are coupled to respective pairs of electrical connection pins of the second connector via shielded differential cables inside the housing.

A cable assembly and a cable connection component are provided. The cable assembly includes a cable and a cable connection component. The cable connection component includes a first outer metal member, a second outer metal member and a holding component. The second outer metal member has an end for interlocking with an end of the first outer metal member. The holding component is disposed between the first outer metal member and the second outer metal member. The holding component includes two inner metal members that are fixed to each other by a fixing member. Each inner metal member includes a wire slot, the wire slot includes an end section and two branch sections, the two end sections jointly hold a portion of the cable in place, and each branch section of the two inner metal members jointly hold one of core wires of the cable in place.

A magnetic grounding technique implements a magnet assembly. The magnet assembly may be soldered to a component to facilitate grounding of a metal shield layer of a cable assembly. A cable plating may be plated onto an exposed part of the insulator of a cable assembly to form the cable assembly, and which galvanically contacts the metal shield layer of the cable assembly. The cable plating may comprise an electrically conductive and magnetic material to ensure magnetic attraction with the magnet assembly. The magnetic assembly is thus magnetically attracted to the cable plating, and also provides galvanic contact between the cable plating and, in turn, the metal shield layer of the cable and ground to reduce RFI. The magnet assembly also magnetically aligns the cable connection pins with those of a mating connector, thus reducing the strain placed on the connectors.
