| 摘要 |
An optical fiber having a multi-material coating and a fabrication method therefor are disclosed. The coating includes at least two portions adjacent in a longitudinal direction. Adjacent portions are comprised of different materials having different Young's moduli. The invention provides a multi-material coating for an optical fiber and coating fabrication method wherein the interfacial shearing stress for the multi-material coated fiber is less than the interfacial shearing stress for a substantially like fiber coated with only one of the materials found in the multi-material coating. Further disclosed is a telecommunications system and fabrication method, wherein the system comprises multi-material coated fibers having reduced interfacial shearing stress.
