“…The main limitation of the optical wireless solutions for longer distances is the communication link bad performance due to atmospheric attenuation and scintillation which lead to turbulence 9-12 . Relay and multiple input multiple output optical systems are proposed to overcome the turbulence phenomenon which limit the practical range [13][14] . Introducing optical transceiver for long-haul trunk lines has been proposed 15 .…”

Wireless optical communication solutions have quickly emerged the market. They are actually considered as potential alternative to fiber optic solutions that are currently the most claimed technologies in terms of data rate. The main issue for this technology besides providing low cost and high data rate link service is to ensure continuity and quality on the provided link. To achieve this goal, it is necessary to investigate the factors that could disturb the link. In this paper, PMD (Polarization Mode Dispersion) in FSO has been investigated. PMD is induced from a delay between propagation modes, using polarization sheets we might seclude one of the propagation modes and avoid dispersion. Two different approaches have been considered: the received power depending on the polarization angle and the average data rate according to vertical or horizontal propagation. Based on experimental tests, PMD and its impacts on transmission delay have been evaluated.

“…The potential scalability of such a hybrid system, integrating surface normal optoelectronic devices with free-space interconnects, has been theoretically assessed [1]. A demonstrator called the optical highway (OH) [7] has been built and experimentally assessed [11] in order to illustrate this potential and to validate this architectural approach to parallel optical interconnects. One important issue emerging from this demonstrator lies in the constraints that the imaging properties of the interconnection system put on the design of optoelectronic interface.…”

“…The bandwidth of a physical link within an optical highway of more than one stage is limited by the dissipation of optical power between the stages (i.e. detector/receiver limited) as indicated by Layet et al [6]. Further, the operating speed is linear in power dissipation (e.g.…”

SUMMARYThe list of applications requiring high-performance computing resources is constantly growing. The cost of inter-processor communication is critical in determining the performance of massively parallel computing systems for many of these applications. This paper considers the feasibility of a commodity processorbased system which uses a free-space optical interconnect. A novel architecture, based on this technology, is presented. Analytical and simulation results based on an implementation of BSP (Bulk Synchronous Parallelism) are presented, indicating that a significant performance enhancement, over architectures using conventional interconnect technology, is possible.
