Local analysis of stimulated Brillouin interaction in installed fiber optics cables

Brillouin gain spectrum measurement along an optical fiber has recently gained a lot of interests owing to its potentiality for strain monitoring in installed telecom cables. The purpose of the paper is to show that this potentiality is now effective, since field measurements of installed fiber optics cables currently in operation are demonstrated. A portable instrument has been developed, based on an original experimental configuration developed in our Institute which is briefly described
