Underwater sonar system is a technology used for ocean exploration, navigation, and communication, widely applied in military, scientific research, and commercial fields. It detects underwater objects such as submarines, schools of fish, or seabed terrain by emitting and receiving sound wave signals. Underwater sonar can not only be used for locating underwater objects, but also assist in studying the marine environment and bottom structures.
Underwater sonar fibers utilize fiber optic transmission technology to enhance the data transmission capability of sonar systems, especially in deep-sea environments. Fiber optics can provide high bandwidth and anti-interference performance, which is a key part of ensuring clear and fast transmission of sonar signals. Fiber optic pipelines are commonly used to connect underwater sensors with ground equipment, ensuring stable signal transmission.
Why does it need to be sealed?
The working environment of submarine sonar fiber optic pipelines is extremely harsh, especially in deep-sea environments. Submarine pipelines must withstand water pressure, mechanical stress, and possible temperature changes. In addition, moisture and other pollutants in underwater environments may infiltrate the interior of pipelines, affecting the performance of optical fibers and even causing equipment damage.
In order to ensure the stability and long-term operation of the system, it is necessary to fill the pipeline. This not only provides a sealing effect to prevent the intrusion of moisture or pollutants, but also enhances the mechanical strength of the pipeline, reducing the impact of vibration and external forces. Filling materials help maintain good performance of fiber optic pipelines and ensure efficient operation of the system.
