Extended reach 32-channel dense spectrum-sliced optical access system
2016
In this paper, we report on 32-channel dense wavelength division multiplexed passive optical network (WDM-PON) with shared amplified spontaneous emission (ASE) light source. Proposed transmission system enables to simplify the architecture of PON network and has a dense channel spacing of 50 GHz as well as it is fully compatible with ITU-TG.694.1 DWDM frequency grid. We investigated the performance of next generation passive optical network (NG-PON) compatible dense spectrum sliced WDM-PON system (SS-WDM PON) with 32 directly modulated 10 Gbit/s channels located in the optical C band. It is shown that maximal transmission distance for SS-WDM PON system can be increased by 23.8% if standard SMF fiber is being replaced with NZ-DSF fiber. Post FEC error free transmission has been demonstrated for all 32 channels over different optical fiber types (SMF and NZ-DSF) and line lengths of at least 100 km.
