FOTDR相干型振动光缆

FOTDR Type Vibration Sensing Cable

产品描述Description

FOTDR型振动光缆专为瑞利相干型系统研制的振动传感 光缆，针对此类型的系统作了优化处理。光缆由PBT充油束管、加强钢丝以及外护套组成。振动光纤置到PBT松套管内，周围是油膏填充。光缆敏感性适中，防水性好，可于挂网、嵌入、埋地等场合。

FOTDR type vibration sensor cable is designed for Rayleigh interferometer vibration system. The cable consists of PBT oil - filled loose tube, reinforced stranded steel wires and PE outer sheath. The vibration fiber is placed into the PBT loose tube, and the surrounding is filled with oil. Cable is good vibration sensitive, good water resistance, and it is widely used in several fields.
