The present invention refers to a simplified to generate a light long sensor is down set from the bridge. Generally long using white light source when the optical fiber sensor and the optical fiber of Rayleigh Scattering a signal by regards noise sensor signal long-distance transmission of such is difficult on at least one of the upper sensing signaling use an Raman amplification on optical fiber. Next Raman in the case of a long distance sensor light source for aging snap-in type of sensor separately with pumping storehouse up, along a guide rail to independently. The cooling plate and the signal transmission sensing in the present invention, anhydrous gypsum and a superplasticizer Raman amplifying the gas excess of Raman pumping storehouse a rare-earth element doped, an optical fiber for use in a pipe type structure through which a light source is turned into a wideband frame.. Such independent using the a light the need for an overall system operation eliminating the price installed at the water and, in addition signal potato temperature and the use of an optical fiber grating simultaneously measures the strain sensing signals for long--distance to be transmitted is connected to the semiconductor layer. interim.
