摘要: Free Space Optical (FSO) communication links are although extremely vulnerable to atmospheric adversities, multi-hop relay transmission can however, significantly improve the link performance and reliability. This paper proposes 120 Gbps DP-16 QAM modulated serial FSO with coherent reception for delivering medical consultation services in remote isolated locations. Considering current situation wherein pandemic of highly infectious nature, COVID-19 has affected millions people globally; doctors use proposed high-speed architecture “contact-less” supervision quarantined patients suspects through video conferencing. Each terminal uses an all-optical amplify-and-forward technique Erbium-doped fiber amplifier (EDFA) gain optimization as its core elements. As a possible last-mile application medical/health care services, been evaluated reliability by exposing varied conditions. Our results reveal that at target BER $10^{-5}$ , useful range increments 1.8 kms compared direct operates under similar channel Furthermore, from recent literature on [30], shows enhancement approximately 0.7 km. The analysis also reveals number nodes increases, error different conditions approaches state convergence.
