Spiral steel tube armored vibration optical cable is a kind of sensor cable which is designed for micro vibration system,it takes double layer stainless steel armored sheath to protect the optical fiber,it has high performance of tensile,resist compression,anti-twisting,anti-rate biting,anti-cutting,water-proof and so on,due to above characteristics,it can suitable for all kinds of bad weather.the structure of optical fiber cable is very clear:optical fiber is protected in a steel tube , the micro vibration is very sensitive to the outside world,it is the ideal of sensor detecting unit of distributed vibration.it is widely used in airports,power plants,chemical industry,military,boundary,prison,oil pipelines,communication cable,power cable,railway,highway,community,schools,mines,big medium and small size factories,enterprises and so on.
