A system for making temperature and pressure measurements distributed over a distance comprises a plurality of Bragg grating measurement points disposed in an optical fiber with a predetermined spacing between adjacent Bragg grating measurement points and a substrate with the optical fiber disposed thereon, at least a portion of the optical fiber being wrapped around the substrate with at least one predetermined wrap angle, wherein the predetermined wrap angle and predetermined spacing are selected to enable a temperature measurement signal to be distinguished from a bending measurement signal, wherein the substrate has a first coefficient of thermal expansion greater than a second coefficient of thermal expansion of the optical fiber and wherein the substrate comprises a hollow tube portion and a solid rod portion, each having optical fiber disposed thereon.
