Optimization of Repeater Spacing for Terrestrial and Undersea Fiber Optic Communication
Repeater spacing in fiber optic communication is optimized taking into consideration various parameters such as fiber attenuation, Stimulated Brillouin Scattering (SBS), Stimulated Raman Scattering (SRS), fiber attenuation, photodiode sensitivity and input power. In the authors' paper, they have taken a trade off between power threshold in order to reduce SBS varying the effective fiber length and effective fiber core area. Also, the authors have obtained results for various repeater spacing. Repeaters are basically used in Long Haul optical fiber communication and undersea fiber optic communication in order to increase the signal strength. Generally, when a signal propagates for long distances, its strength degrades and will be badly affected by noise.
