Abstract :
Brillouin optical time-domain reflectometry (B-OTDR) operated in the 1.60-1.65 μm wavelength region is a promising technique for in-line monitoring and preventive maintenance in optical fiber networks. This paper presents strain and optical loss distributions measured in 30- and 100-km-long optical fibers, respectively
