Abstract

The invention relates to an opto-electronic combined trailing cable used for a hydrophone system. The cable comprises a shielding signal line, power lines, optical units, and an outer sheath. The cable is characterized in that the shielding signal line is on the center of the cable, the power lines and the optical units are stranded around the shielding signal line to form a cable core, a nonmetal reinforcing element wraps out of the cable core, and the outer sheath wraps the nonmetal reinforcing element. Low-density or medium-density polyethylene is used in the cable to ensure the density of the opto-electronic combined trailing cable slightly larger than density of seawater, and by using seawater buoyancy, energy source loss in the hydrophone system is reduced. Optical fibers are high-strength anti-bending single-mode fibers, and torque balance is realized in the cable structure and technology, and transmission loss of the optical fibers is controlled, so as to ensure reliability of optical signal transmission and obtain better detection effect. The opto-electronic combined trailing cable is high in tensile and torsional strength, and flexibility of the optical fiber is ensured, and the cable has good transmission stability and reliability.

Description

technical field [0001] The invention relates to a photoelectric composite trailing cable, which is mainly used in a hydrophone system and has the functions of sending, receiving and transmitting optical signals. Background technique [0002] Large-scale optical fiber hydrophone system is of great significance in obtaining seabed address structure parameters, seabed oil distribution, marine environmental parameters and underwater target information. In practical applications, the light emitted from the light source is transmitted to the underwater optical fiber hydrophone system through the towed optical cable, and the underwater acoustic signal is converted into an optical signal by each optical fiber hydrophone, and the light containing the underwater acoustic information is then transmitted through the towed optical cable To photoelectric signal processing, multi-channel digital sound signals are obtained through photoelectric signal processing and demodulation.
