LightPointe's FSO is a carrier-class technology. LightPointe is an established name in the US for laser connections. The company, an authorised member of Cisco Systems' Ecosystem Partner Program, offers technology that is transparent to any network protocol. In the US, privately run MANs and large-campus corporate networks make use of this system. In the local market, however, this is first and foremost a carrier- or service-provider level solution. It is perfect for metropolitan distribution of broadband data services and avoids the limitations and expense of wireless and fibre broadband systems.
