1. A system for use with a subterranean well, the system comprising:

  • multiple well tools installed at longitudinally spaced apart locations along the well, each of the multiple well tools are encompassed in a side-pocket mandrel disposed in the well, each of the multiple well tools including a sensor to measure one or more downhole parameters and an acoustic transmitter which wirelessly transmits an acoustic signal including information representative of a measurement of the one or more downhole parameters by the sensor, and wherein the multiple well tools are configured to change a data source, a data rate, a modulation technique, or a transmitting frequency on command from a surface controller;

    an optical waveguide positioned in the well, wherein the optical waveguide is present at each of the locations, the optical waveguide sensing the respective acoustic signal from the respective acoustic transmitter at the respective location for each of the multiple well tools; and

    an optical interrogator positioned at a surface of the earth and connected to the optical waveguide, the optical interrogator thereby receiving the respective information representative of the respective measurement by the respective sensor for each of the multiple well tools.
