We introduce the Cascaded Bit-interleaved optical network protocol, an energy-efficient solution aiming to achieve low power consumption in converged optical access/in-building networks while providing high data rates to end-users, and propose a novel network architecture for optical access/in-building networks. In the proposed network architecture, optical-electrical-optical (OEO) regeneration is employed at the interface between access and in-building networks. The downstream frames are generated in the central office using a two-stage bit-interleaving scheme. In the downstream direction, the network nodes only process the data destined for them at a lower clock rate than that of the aggregate passive optical network (PON). In the upstream direction, no word alignment or decoding is performed in the intermediate nodes. We present detailed simulation and experimental results we obtained and show that a significant reduction in the power consumption of access/in-building networks can be achieved when the proposed Cascaded Bit-interleaved Protocol is employed in conjunction with the proposed network architecture.
