振动光缆系列产品简介

Brief introduction of series optical cable vibration

光纤振动传感报警系统是一项基于光干涉原理来测量外界振动、声音的一项技术。它的原理是将两束相同（同频率、同相位、同时）激光入射到光纤中，并在光纤中形成稳定的干涉现象。当外界的挠动（如挖掘、触碰、敲打、甚至声音的振动）对光纤产生轴向的挤压时，会引起入射光在这个区域发生变化（衰减、相位、波长、极化、模场分布和传播时间），这种干涉平衡的现象就被打破。通过分析仪，我们可以调解出这种变化的强度、频率和位置，通过大数据分析，判断出其入侵类型，从而输出报警信号。振动光缆（光纤）在这里充当了传感器的重要作用。

新科凯邦公司针对光纤振动传感报警系统的实际应用领域、工况、环境和性能的要求，研制出各种不同的振动光缆，有减敏型的、增敏型的、挂网式的、埋地的、单纤干涉型的、双臂干涉形的等等，以满足不同的系统，不同的应用场景的需求。

应用场景∶

1.机场周界安防 2.化工厂、危化品仓库 3. 4. 5.高档小区 6.国防边境 7.变电站、电厂

Optical fiber vibration sensor alarm system is a technology lased on the principle of optical interference to measure the external vibration and sound.Its principle is that two identical(same frequency, same phase, and same time) laser beams are incident into the optical fiber, and stable interference phenomenon is formed in the fiber. When the external torsion (such as digging, touching, knocking, and even sound vibration) produuces axial squeezing on the optical fiber, the incident light will change in this region (attenuation, phase, wavelength, polarization, mode field distribution and propagation time), and the interference balance will be broken. Through the analyzer, wecan adjust the intensity, frequency and location of this change. Through big data analysis, we can judge its intrusion type, andthen output alarm signal. Vibration optical cable (optical fiber)plays an important role in the sensor.According to the requirements of practical application field, working condition, environment and performance of optical fiber vibration sensingalarm system, Xinkekaibang photoelectric company has developed various vibration optical cables, including desensitization typee, sensitization type, hanging network type, buried type, single fiber interference type, double arm interference type, etc.,to meet the requirements of different systems and different application scenarios.Application scenarios:1. Airport perirmeter security 2. Chemical plant and dangerous chemicals warehouse 3.Prison 4.Government agencies 5.High grade residential area 6. National defense border 7. Substation and power plant
