Abstract :
This letter proposes and demonstrates two, 100 and 200 km, long distance fiber laser systems for fiber Bragg grating (FBG) sensors multiplexing. The first system is based on a fiber ring laser and reaches 100 km, whereas the second one is composed by a random fiber laser with a reach of 200 km. Both of them are able to multiplex 11 FBGs. In addition, because of the mode operation of the systems, they are low noise configurations.
