Dual Band Bend Insensitive Fiber

These germanium doped Single-Mode (SM) fibers offer excellent performance in tight space environments and are available with a 9.8µm core size. This is compliant to ITU standard G657.A2.

These fibers are designed to withstand harsh environments such as high temperature, high pressure, moisture, and chemicals. Applications in oil and gas, data transmission, offshore oil and gas asset monitoring, Enhanced Oil Recovery (EOR) (especially Steam Assisted Gravity Drainage (SAGD) techniques), borehole seismic and avionics can benefit by using these fibers.

Fibercore has developed a unique carbon coating, which offers significant barriers against hydrogen, moisture fatigue, and acid ingression. The carbon coating also increases the lifetime of a fiber under tight and sharp bends, protecting the fiber from water/moisture attack/(micro-cracking) to the fiberglass surface.

These fibers are available with high temperature acrylate, polyimide, carbon & high temperature acrylate, and carbon & polyimide.

  • Low weight/small size avionics cables
  • Data center transceivers
  • Oil & Gas distributed sensors
  • Silicon photonics
  • Well integrity monitoring
  • FBGs for strain and temperature monitoring where tight bends are required
