摘要
We propose and experimentally demonstrate a novel wavelength-division-multiplexed passive optical network (WDM-PON) scheme for the suppression of adjacent crosstalk arising from the wavelength misalignment in arrayed waveguide gratings (AWGs) between a central office (CO) and a remote node (RN). The adjacent crosstalk suppression is achieved by allocating two different bands to adjacent channels of the AWGs by utilizing interleavers and WDM filters. The transmission performance of the proposed scheme was measured at a 155 Mb/s data stream, and error free transmission with a power penalty less than 0.7 dB was successfully achieved in case of AWG misalignment of 0.3 nm.
