Optimal design of spectrally sliced ASE seeded WDM-PON system

The spectrum sliced dense wavelength division multiplexed passive optical network (SS-DWDM PON) is a cost effective and power efficient solution for passive optical access networks to satisfy the growing worldwide demand for transmission capacity. In this paper we successfully demonstrate the investigation of 16 channel high-speed SS-DWDM PON system with data rate 2.5 Gbit/s per channel where broadband ASE source is realized using two EDFA amplifiers in cascade mode. Originally resulting ASE spectrum on the output of EDFA is irregular and manipulation with EDFA parameters must be done to make it more flat. Flat optical spectrum of ASE source is an important premise to achieve minimal output power level fluctuations of obtained channels after spectrum slicing and provide stable data transmission with BER<;1·10^-10 over the specified fiber optical link length. Maximal reach of realized SS-DWDM PON system is evaluated as well as the performance of proposed broadband ASE source.
