Paper Abstract

The preferred method for ultra-high bandwidth in communications has been the optical. This is mainly due to the demand for more bandwidth, which the 1300-1650nm band of light offers in an optically transparent medium, air or fiber. Although fiber technology has been advanced to produce a wide range of fiber types to meet specific needs, fiber deployment requires long-term planning and installation that culminate to long delays till full service is established. There are applications that demand high-data rate connectivity urgently, either because of natural emergencies or because the private sector cannot wait for the long planning and deployment. Thus, an alternative communication method is free space optical. This method uses a laser beam that is directed from a building to another to establish full-duplex point-to-point high-data rate connectivity. However, this technology has been limited to a point-to-point topology. In this paper we present a free space optical integrated node design suitable for mesh and/or ring topology with full connectivity. We also discuss engineering aspects, traffic management, fault management and security issues.
