There are two key benefits of PFCS technology. First, such systems are independent
of the underlying data transmission rate because they do not regenerate the signal
electrically. They can truly serve as a means of wireless fiber extension. Second, such
systems (when designed with the right kind of optical components) can support multiple
wavelength transmission, making them viable for transmission of WDM signals.
Both of these benefits can bring the virtually unbounded capacity of the fiber-optic
world to the wireless world, something that will never be matched by RF wireless
technology.
Such systems, even though proven in the field at data rates as high as 40 Gbps, have
yet to find their way into mainstream FSO product offerings in a commercially viable
way. However, as demand increases and technology advances, costs will continue to
decrease, enabling such FSO technology to enter the mainstream communication world
as an economically viable technology.
Optics Optics is a key component of FSO technology, and this is where it differs most
significantly from fiber-optic technology and draws closer to RF wireless technology.
Optics in FSO systems play the same role as antennas in RF communications.
