Paper Abstract

In this paper, we propose an all-optical real-time data format conversion system to realize the efficient-utilization of the spectrum resource in the FBG sensing network. In the data format conversion unit, frequency domain sensing signals reflected by FBGs are converted into optical time division multiplexing signals with a specified wavelength in real time. Format converted data from each node are sent back to the control center for demodulation. Experimentally, data format conversion and demodulation of one sensing node is carried out with different temperature and static strain. The spectra of sensing pulses before and after data format conversion indicates that the data format conversion is successful and the spectrum resource in this node is released.
