Abstract
Free space optical (FSO) technology is a quick-to-deploy and economical way of getting access to the fiber optic network. FSO technology not only offers fiber-quality connections, but it also offers the sector’s cheapest transmission capacity. FSO systems complement legacy network commitments and function in harmony with any protocol, saving significant up-front investments as a completely protocol-independent broadband gateway. An FSO link may be purchased and deployed at a fraction of the cost of installing fiber cable and for roughly half the cost of equivalent microwave/RF wireless systems. With exception of RF wireless technologies, FSO does not need the purchase of expensive spectrum licenses or the fulfillment of additional regulatory criteria. The purpose of this study is to examine the performance of FSO-based optical access networks. Analysis of the performance in detail, with a focus on BER is also described.
