Abstract :
The authors propose the use of Optical Frequency Domain Reflectometry (OFDR) in the multiplexing of Fiber Bragg Gratings (FBGs) of differing wavelengths that are installed equidistantly, and are developing a system for measuring reflected wavelength in real-time. We have demonstrated that how the wavelength sweep width of a tunable laser was expanded to 30nm and multiplexing of FBGs of five different Bragg wavelengths and multi-pointing of FBGs of the same Bragg wavelength was done. This paper describes that this measurement system is able to measure the reflected wavelengths of each of 26 multiplexed and multi-pointed FBGs, every two seconds in real-time.
