This review summarizes recent progress and emerging trends in multiparameter optical fiber sensing, emphasizing techniques that enable the simultaneous measurement of temperature, strain, acoustic waves, pressure, and other environmental quantities within a single sensing network. This perspective article delves into the current performance limitations of distributed optical fiber sensors and proposes avenues for future advancements, as envisioned by the author, whose four-decade-long career has been dedicated to this transformative field. These are reliable and easy-to-use devices that have high power, can automatically adjust to real-time conditions, and have a straightforward display that eliminates any guesswork. Sensing is achieved by. application areas by the use of distributed fiber-optic sensor (DFOS) systems, which can be formed by combining fiber sensing and telemetry [l-l 11. In the case of intrinsic distributed.
