Thanks for reading and sharing your insight on terahertz and fibre optics @onderkcaalan. And i did mention that this is going to be futuristic, in the sense that research on its benefits and its application are still ongoing. About SBS, i agree that it could be an issue with fiber optics, because it usually occurs when the amount of light being passed into the fibre exceeds the power level threshold suited for the launch and transmission process. However, this won't be much of an issue, as the researchers are still working to ensure the application of Terahertz is seemlessly achieved in telecom. The potential of speed which it boasts of, and the radiation free wavelength transmission, would definitely make it a choice of the future; as the present day gigahertz, would eventually be unable to sustain our need and demand for faster speed of transmission of data in the no-distant future.
