Abstract
A new scheme is proposed for sensing distributed strain and temperature in optical fibers. This scheme uses Brillouin scattering as the sensing mechanism and a branched optical fiber network as the sensing fibers. Brillouin optical time domain reflectometry (OTDR) makes it possible to distinguish Brillouin scattered lightwaves from different optical fiber branches in the network when different Brillouin frequency shifts are assigned to each branch.
