【Abstract】 Based on fiber profile design, the measures improved for single-mode fiber bend sensitivity are proposed. Utilizing the PCVD process advantage and the employment of the coating with low bend loss characteristic during drawing process, the bend non-sensitivity single-mode fiber with low water peak attenuation are fabricated. The microbending and macrobending performance of this kind of fiber are researched and the effect of the fiber profile structure on bend loss is analyzed.更多还原
