In this article, a novel idea of a hidden bit channel established in the downstream passive optical network (PON) frames is proposed. As the downstream frames in time‐division multiplexed, PONs are broadcasted and delivered to all active end‐point optical network units (ONUs), and this bitstream could be potentially used for creating an additional hidden bit channel containing bits for all ONUs. Therefore, the downstream frames could simply transmit standard information fields and ONU contributions according to the standard PON principles; however, these bits could be also reused multiple times to carry additional data for each ONU in a form of segmented bit sequences spread within the entire bitstream. To establish effective bit channel with positive bit gain, an effective algorithm for addressing its bits is necessary. The most promising bit addressing algorithm is proposed within this article together with the results obtained by its simulations and performance evaluations. © 2015 Wiley Periodicals, Inc.
