Performance Analysis of Modulation Formats for WDM Spectrum Slicing

Jamal N. A. Hassan | F. E. Ismael | Elsadig Saeid

Abstract: The spectrum slicing technique of wavelength division multiplexing system is attracting more market recently since it is power efficient and less costly than the traditional laser sources. In this paper Continuous Wave (CW) array lasers element are utilized instead of de-multiplexer to reduce more cost and simplify the WDM system design structure. An erbium-doped fiber amplifier (EDFA) module is also used for laser power level enhancement. Data from different sources were transmitted to evaluate new WDM like system. Furthermore, spectrum slicing, modulation formats is used to analyze the relevant performance parameters. Optisystem14 software was used to design, implement and simulate the passive optical system of WDM. It is found that The NRZ system has been found to be good for transmitting optical signal at the rate of 8Gb/s and 60 km length.
