Seismic cable is an important component of cable seismic instruments. The technical characteristics of the seismic cables are not only directly related to comprehensive performance and application effect of seismic instruments, but also directly related to overall efficiency of seismic exploration. Sometimes it is even related to the quality of seismic data. Taking the actual demand of seismic exploration and seis-mic instruments application as the goal, this paper discusses the characteristics of seismic cable’s data transmission and field operating sys-tematically, and clearifies the key technical characteristics’ physical significance, main role and calculation method on the basis of general symmetrical communication cable technique. Combined with practical work experience, it also gives the suggestions to enhance the technical characteristics and improve the application result of the seismic cable.
