Question

What are losses in optical fiber and how can be they minimized?

Answer 1

 reduce optical fiber losses, Rayleigh scattering loss, infrared absorption loss, and losses due to imperfections should be reduced. Among these, Rayleigh scattering and infrared absorption losses are highly affected by used dopant. On the other hand, losses due to imperfections depend not only on the fabrication process but also on the viscosity properties of the core and cladding materials. To reduce loss due to imperfections, the viscosity matching of core and cladding materials is quite effective.  T
