Problems solved by technology

Due to the limitation of the structure of this cable, in order to achieve a good crosstalk effect, the pitch must be made very small, otherwise the relative position of the two core wires of the pair is easily displaced and changed during the subsequent manufacturing process. As a result, the cable transmission performance is unstable, crosstalk occurs during transmission, or the impedance is uneven
However, the negative impact of too small pitch is to increase the attenuation, thus affecting the transmission distance

Abstract

The invention relates to a compound rope of a cable rope and an optical rope, belonging to the compound rope technical field. The compound rope of the cable rope and the optical rope comprises a twisted wire core and an optical fiber core which are provided with sheathing layers at the outside, and the twisted wire core conductor is provided with a coated insulating layer. The compound rope is characterized in that a framework, the twisted wire core and the optical fiber core are arranged in the groove of the framework. The invention has the advantages that the interval is increased and steady, the mutual interference can be restrained effectively, the overhearing can be reduced, the transmission stability of data ropes can be improved, wider bandwidth can be transmitted and the mechanical tensile property is good.

Description

technical field [0001] The invention belongs to the technical field of composite cables, in particular to a composite cable of electric cables and optical cables. Background technique [0002] At present, with the rapid development of communication technology and the continuous expansion of computer networks, the amount of extension and transmission information has increased sharply. On the one hand, the amount of data cables used for communication network cables has increased by a large margin; High transmission speed and better transmission effect to achieve fast and accurate transmission of information. At present, the known data transmission cables are generally unshielded twisted-pair cables utilizing four or more pairs of wire groups. It is two uniform insulated wire cores and twisted together in the same direction to form a wire pair group, and then formed into a wire pair group. The cable is finally covered with an outer sheath. Due to the limitation of the structu...
