Patients who are in healthcare places need for continuous healthcare monitoring system for long periods to surveillance human body vital signs. This system should be secure, reliable, and guarantee not to interfere with available radio frequencies or sensitive electronic devises such MRI (magnetic resonance imaging) since it deals with human life. In this paper, we designed, implement and evaluate a prototype model for Li-Fi healthcare monitoring system over different propagation links as an integrated optical system. The key idea of the created system is to remove the optical background noise power and to ensure patient's mobility at distance up to 4 m and 2.5 m in Los (line of sight) and diffuser links respectively. The system is created to receive data from a fibre Bragg gratings sensor (FBG) that will be sent to the end receiver through different propagation links having 100% accuracy. Also, it is particularized with low power consumption, low-cost components, and could be adapted to different other systems of sending or processing operation. The proposed system provides, much more accurate received data compared to previous related literature.
