Development of SS-WDM and High Speed SS-WDM

Multiplexing is a term used to refer the process where multiple analog or digital signals are combined and transmitted through same transmitting media. The technology of combining a number of such independent information carrying wavelengths onto the same fiber is called Wavelength Division Multiplexing (WDM). The conventional WDM system can hardly be applied to systems that require high data transmission rate regardless of short haul or long haul transmission line. But now-a-days, the demands for high data transmission are increasing and also the use of lasers as source in WDM systems had increased the overall cost. To overcome these issues a new technology called spectral slicing was developed which brings WDM technology one step more ahead of advanced technology. In spectral sliced WDM system, LED or ASE can be used as the low cost broadband source. These sources have high broadband spectrum, so it can be sliced spectrally into many independent signals with equal channel spacing. The main advantages of using Spectral Sliced WDM(SS-WDM) system includes low cost and high channel capacity. Here, in this paper the realization of spectral sliced WDM system using NRZ and RZ modulation formats is performed and evaluate the performance of the system for use in various optical access networks using Optisystem 12.
