N2 - Free space optical links (FSOL) applications have been considered as a potential medium to provide short range links using simple and compact equipment. The development of radio on free-space optical links (RoFSOLs) has also proved effective as a short link. In RoFSOLs, some radio on fiber signals are directly transmitted from an optical fiber into air. This can provide a free-space link for various types of wireless services in an optical wireless beam similar to RoF. RoFSOLs can provide another method to extend mobile network infrastructure, where radio signals from a base station analog-modulate an optical signal at a radio-to-optical signal converter (R/O) using a laser diode or a optical external modulator. RoFSOLs without fiber or a combination of RoF and RoFSOLs are suitable for universal backhaul link and a universal access point for heterogeneous wireless services. RoFSOLs, in combination with WDM technology, can provide shared backhaul for flexible deployment of various wireless services operating in different radio frequency bands.
