Challenges with Fibre optics

  • There is a challenge of managing capital and operating costs while building a future proof network.
  • The single mode fiber optic that is used its cost is relatively high compared to multimode fiber.
  • Difficulties of connection between 2 fibers.
  • Difficult derivations.
  • High cost of installation fragility within the country.
  • Depending on application and environment, optical fibers need to be coated for both mechanical and chemical protection which is expensive for the country.
  • Increased optical attenuation from hydrogen induced losses (hydrogen darkening).
  • There is decreased mechanical strength due to moisture corrosion and chemical attack.
  • The main challenge for these fiber sensors is to identify and differentiate between noise and actual acoustic event.
