Improve the performance of spectrum-sliced WDM PON systems with FEC
Abstract: Firstly l,this article introduce advantages and basic principle of spectrum-sliced WDM PON. at the same time, analyze its disadvantages in detail, such as low spectrum efficiency, the multiplexed number is few, low data rate and so on . FEC is adopted to improve the performance of spectrum-sliced WDM PON system.
Keywords: Spectrum-sliced FEC WDM PON signal-noise ratio spectrum efficiency
