Abstract	In pervasive computing, fiber optic can be adaptive to smart apperceive the complicated environment because of the sensitivity. This paper analyzed the influence of the measurand-strain (axial strain and radial strain) and temperature effect on propagation wave phase in fiber-optic sensors. The equations of propagation wave phase shift caused by strain and temperature change were deduced, and sensitivity coefficients of strain and temperature were obtained. Then we described the cross-sensitivity's physical mechanics of the fiber sensor and obtained cross-sensitivity coefficient. With double wavelength single detecting the change of strain and temperature simultaneously, the cross-sensitivity can be solved. Using the highly elliptical core two-mode fiber as the sensing fiber, two wavelengths 580nm, 600nm as sensor signal, the linear equations were obtained. The relationship of the strain (and temperature) against the two wave phases shifts was showed
