光纤技术可以给传感器设计提供一种革新方法,由于光纤传感器是介电器件,所以不受多种电磁干扰(EMI)和电磁脉冲(EMP)的影响.正因为如此,光纤传感器可用于远离其有关电子设备的苛刻的环境中,此外,光纤有较宽的通频带,允许高速数据传送,而且光纤的衰减要比铜导线小.除了光缆具有尺寸小,重量轻的优点之外,由于在光缆上搭线窃听困难而不会引起探测损失,与同轴电缆和铜导线相比较可以增加其可靠性.
Fiber optic technology offers a revolutionary approach to sensor design that is immune to many types of electromagnetic interference (EMI) and electromagnetic impulses (EMPs) because fiber optic sensors are dielectrics. Because of this, fiber optic sensors can be used to move away from them Electronic equipment in harsh environments, in addition, the optical fiber has a wide passband, allowing high-speed data transmission, and fiber attenuation than the copper wire. In addition to the small size of the cable, the advantages of light weight, due to the optical cable Wire tapping difficult without causing detection losses, compared with coaxial cables and copper wire can increase its reliability.
