The invention discloses a residual cable stand and an aerial optical cable connecting structure using the same. The residual cable stand comprises a main stand body, wherein the main stand body comprises an entry portion and a leading-out portion, the main stand body is provided with a suspension structure, and the entry portion and the leading-out portion are each provided with a supporting arm. According to the residual cable stand, the entry portion and the leading-out portion of the main stand body are each provided with the supporting arm, the supporting arms can be used for stretching an incoming section and an outgoing section of a residual cable relatively, so as to support the incoming section and the outgoing section of the residual cable, thus the incoming section and the outgoing section do not twist in a relatively closed manner, and overturn torque applied on a twisted portion of the residual cable caused by deformation of the incoming section and the outgoing section is avoided, thereby ensuring that the residual cable stand can be suspended on a main cable under the connection of the suspension structure without being fixed on a tower body of a pole tower, saving a residual cable leading out from a connecting portion of the main cable toward the pole tower, reducing waste of an optical cable, and having the functions of saving optical cable and facilitating operation maintenance.
