Analysis study of quality factor and bit error rate at wavelength change

Abstract

Gigabit-per-second data speeds can be achieved via free space optics (FSO) lines, which needless system complexity. On the other hand, the link's availability across a wide range of atmospheric circumstances is a major worry. As a result of the increased signal attenuation caused by the linkages being weather-dependent, their efficiency decreases. Up to 70 dB/km of attenuation can be caused by bad weather on a 500-meter free space optics link. In this work, transmission windows of 1310 nm, 850 nm, and 1550 nm are analyzed and compared using the free space optics link. by using the Simulation program opti system such as the quality factor, the minimal bit error rate (BER), and the eye diagram is taken into account. Analyzer findings are compared to establish the optimal wavelength for a transmitter under poor weather conditions.
