摘要

We present the analysis of a quasi-distributed fibre sensor based on the concatenation of identical low-reflective fiber Bragg gratings (FBGs) taking into account the effect of spectral-shadowing crosstalk. This allows obtaining more realistic values of the design parameters such as the maximum number of sensing points, the reflectivity of the gratings, and the distance between the sensing points.
