FSO, an emerging technology will grow from
its current nascent state to a strong niche player within three years. FSO
equipment currently is being deployed for a variety of applications, such as
last-mile connections to buildings, which may provide the greatest opportunity
since FSO provides the high-speed links that customers need without the costs
of laying fiber to the end user. In 2005, last-mile access will represent over
two-thirds of the total FSO equipment market.
Currently, the increase in high-bandwidth
applications at the edge of the network, coupled with the lack of a high-speed
infrastructure connecting the edge to the core, has turned the threat of a
connectivity bottleneck into reality affecting the end-users, service providers
who face delays in laying fiber and building optical infrastructure, resulting
in incomplete networks, lack of revenue and increased competition. FSO allows
them to provide this optical connectivity cost effectively, quickly and
reliably. Such flexibility makes FSO systems an extremely attractive method for
service providers to truly solve the connectivity bottleneck.
Free-Space
Optics communication systems are among the most secure networking transmission
technologies. Unlike microwave systems, it is extremely difficult to intercept
the FSO light beam carrying networking data because the information is not
spread out in space but rather kept in a very narrow cone of light. To
intercept this invisible light beam, the intruder must be able to obtain direct
access to the light beam. Despite its potential, FSO still has many hurdles to
overcome before it will be deployed widely. Carriers, like Allied Riser and XO
Communications, may use FSO in conjunction with other technologies to expand
their current networks while others, such as Terabeam.
Because
of high availability, bandwidth scalability, and deployment simplicity,
Free-Space Optics has emerged as a solution and deployment option in the
deployment of next-generation wireless networks. As a result of its worldwide
license-free operation, combined with a multitude of applications, FSO is
providing an attractive and cost-effective option for network planners
concerned about fast and reliable network builds, and executives concerned
about faster paths to profitability.
