Dear Miroslav,
all component can be used for free-space optic communication. Th LiFi component is best suited for LiFi, how it is limited to ON-OFF DD system. The other three components are flexible to use any modulation and detection. You may use the LOS component for short distances, FSO for ground level transmission and OWC for ground to satellite transmission. Please check the parameters of each component for your needs.
Regards,
Ahmad
