Seismic sensing and acoustic logging systems using optical fiber, transducer s and sensors are provided. The quartz sensing system includes a quartz sensor , an electromechanical converter, an optical source, an optical fiber and a signal processor. The geophone seismic sensing system has a sensor, a transducer, an optical source and detection unit, an optical fiber and a measurement unit. The acoustic logging system has a sonde for arranging in a borehole of a well such as an oil well. The sonde has a transmitter for providing at least one transmitter acoustic signal, and has receivers for responding to the at least one transmitter acoustic signal, for providing electrical receiver signals containing information about properties of earth formations in the borehole of the well. The acoustic logging system features one or more transducers, a light source, an optical fiber and a detection an d management unit.
