OFS Shape Sensor Optical Fiber

Twisted Multicore Fiber with Continuous Gratings

OFS has developed a technology platform to produce high quality twisted multicore optical fiber with continuous FBGs (Fiber Bragg Gratings) to meet critical 3D shape sensing specifications. OFS expertise in specialty glass preform design makes possible the manufacture of a wide range of fibers with optimized features such as multiple cores, selected cutoff, specific numerical aperture, and core to core spacing.

KEY BENEFITS

  • Customizable high quality gratings provide good signal-to-noise ratio
  • Precisely positioned gratings provide stable signal throughout the fiber
  • No stripping and recoating provides high fiber integrity and strength

OFS’s manufacturing facilities and robust quality management system ensure optimal performance and peace of mind.
