A study on the optical fiber diagnostics using rayleigh back-scattering

In this paper, we have designed and fabricated high speed signal processing unit, optical driver and sensing unit in order to develop a distributed optic fiber sensing and measuring system using the rayleigh backscattering. To define the functions, we have constructed a testing system(1.1[km]), done the characteristics test.
