Abstract
Abstract Free space optics (FSO) can be used as an alternative to the currently used wireless radio communication systems to meet the increasing demands for the uninterrupted internet connection in High-Speed Trains (HSTs). FSO is less prone to interference, license-free and more secure as compared to Radio Frequency (RF) technology. In this paper, we have compared three different wavelengths (850, 1330, and 1550 nm) for the dual-wavelength model at a bit rate of 10 Gb/s to see which two wavelengths provide better results. The system is studied for return to zero (RZ) and non-return to zero (NRZ) modulation formats this electronic document is a “live” template and already defines the components of your paper [title, text, heads, etc.] in its style sheet.
