Cable special for signal receiving and sending connection assembly

The invention discloses a cable special for a signal receiving and sending connection assembly. The cable comprises an inner core body, wherein the inner core body is of a cylindrical structure, two groups of signal lines in parallel are arranged, each signal line comprises two wire cores, an aluminum foil Myra back adhesive wraps the wire cores, an aluminum foil Myra is pasted with an outer side of the aluminum foil Myra back adhesive, a positioning post is arranged between the two wire cores, Myra wraps the signal lines, and a Dennis filler is arranged between the signal lines and the Myra. An insulator extruder is co-extruded by five machines, so that the dielectric constant of a foamed PP strip is stabilized within 1.6-1.7, and each pair of signal lines in 16 pairs of signal lines are enabled to be stable in transmission; an all-in-one machine is arranged outside a total twisted braid, the signal lines are only subjected to winding and unwinding in one time to complete a cable finished product, and the risk that an external force is applied to damage the foamed PP belt is greatly reduced; and by the cable, aggregate bandwidth of over 14.4Tbps can be transmitted, and the demand of rapid data traffic increase of a data center is solved.
