Embodiment Construction
[0014] In the magnetic optical cable provided by the present invention, a single sensing optical fiber 4 or at least two sensing optical fibers are used as information transmission and sensing media, and the coated inner sheath 3, aramid fiber 2, outer sheath 1, and the outer sheath The single diameter is 3mm. Each end of the magnetic optical cable is connected to the instrument and equipment to be monitored. Such as monitoring the oil temperature in the tank and the temperature of the tank body; monitoring the temperature change of bridges and tunnels and fire alarms and other occasions.

The present invention design highlights is the magnetic optical fiber cable sheath having sensing optical fiber, aromatic polyamide fibre filament set between inner sheath and magnetic outer sheath. It is composed of 25-35 per cent neodymium iron boron magnetic particle and 75-65 per cent powdered plastic, through stirring becoming powder plastics having magnetic particle. Said Magnetic optical fiber cable is directly laid and adsorbed structural member and building surface having ferrous material. The inner piece of said optical fiber cable I s parallel each other, uncrossed, stressing uniformly, reducing optical fiber cable generated internal stress, thereby effectively releasing sensing fiber-optic stressing.
Description
technical field [0001] The invention relates to the field of kits for information transmission and sensing media. Specifically, it discloses a magnetic optical cable and how the optical cable is manufactured. The magnetic optical cable can rely on its own magnetic force to be easily adsorbed on the structural parts, buildings, bridges, oil tanks, etc. with ferrous materials to be laid, and used as a sensor. Background technique [0002] With the rapid development of my country's sensing industry, people are paying more and more attention to using optical fiber as a sensor to monitor the temperature and leakage of buildings and equipment. While the optical cable is being laid as a sensor, the positioning and fixing of the optical cable is very important. The movement of the optical cable after laying leads to the failure of the monitoring results. Therefore, the optical cable needs to be fixed continuously during the laying process, and the fixing force should be moderate. ...
