A birefringent launching fiber (BLF) is proposed as a means of reducing backscattered power fluctuations in single-mode fibers that occur during polarization-sensitive measurements. The BLF consists of birefringent single-mode fibers spliced in series. The arrangement of the birefringent single-mode fibers is discussed theoretically and experimentally. Results show the usefulness of the BLF in an optical-time-domain reflectometer.
