A Broadcasting-enabled WDM-PON Architecture Based on Subcarrier Modulation Techniques

We propose a novel broadcasting scheme for WDM-PON access networks and experimentally demonstrate the downstream transmission performance. Broadcasting data is generated via subcarrier modulation technique and the un-modulated carrier acts as the seeder for FP-LD injection locking direct modulation, which is compatible with current WDM-PON infrastructures. 2.5 Gb/s broadcasting data and 2.5 Gb/s point-to-point data are successfully integrated and transmitted in a typical WDM-PON structure.
