摘要

This paper reviews the work on huge capacity fiber-optic sensing network based on ultra-weak draw tower gratings developed at the National Engineering Laboratory for Fiber Optic Sensing Technology (NEL-FOST),Wuhan University of Technology,China.A versatile drawing tower grating sensor network based on ultra-weak fiber Bragg gratings (FBGs) is firstly proposed and demonstrated.The sensing network is interrogated with time-and wavelength-division multiplexing method,which is very promising for the large-scale sensing network.
