Performance Analysis of a Full - Duplex WDM-EPON based System with Fiber to Wireless Optical Network
Wireless technique is speedily becoming more essential during last four decade. Optical wireless channel is a type of communication in which unguided visible, IR, UV light wave is used to carry message signal. Based on transmission range optical wireless channel is used to send message at ultra-short, short, medium, high and ultra-high range. In this paper message signal is send through IR light wave at long range OWC from optical line terminal (OLT), having frequency lying in the range of 750nm-1600nm.On the other hand single mode optical fiber is used at receiver end to carry signal to the optical network unit (ONU).In this paper it is demonstrated that WDM-EPON technology has been successfully deployed in fiber to home which makes system more advanced, cost effective and having very high bandwidth and very high data rate. The proposed bidirectional simulation is made on Optisystem software and analyzed considering Qfactor, BER and power received.
On supporting radio over fiber and passive optical network systems with a common fiber plant: Compatibility aspects
In view of the current prospects in wired and wireless access networks, it is becoming increasingly important to address potential convergence issues between both types of access networks. Therefore, this paper analyzes compatibility aspects of supporting radio signals over a passive optical infrastructure, which must be accounted for to enable the coexistence of fixed and radio access systems over a common fiber plant.
Theoretical analysis of multiple transmitters/receivers on the performance of Free Space Optics (FSO) link
The Free Space Optics (FSO) vulnerability towards atmospheric phenomena has introduced the usage of multiple transmitters/receivers in the FSO system as the optimal solution. With current interest in this technology as an alternative backup to the already established broadband technology, a proper understanding on the performance of FSO link has become vital and thus arise the need to examine the effect of these multiple transceivers on FSO link. This paper gives the preliminary result of the FSO link performance in terms of geometrical losses, power received and link margin using precise mathematical relations regardless of the various atmospheric conditions. Thus, this is the first step towards developing a comprehensive theoretical analysis of multiple transmitters/receivers on FSO link to be used as a benchmark in the practical implementation.
