Fiber To The Home (FTTH) Passive Optical Networks (PON) are widespread in modern access networks. Among PONs, Ethernet-PON (EPON) networks stand out, as they have the advantage of combining simplicity and low cost devices with a wide bandwidth provision. As a matter of fact, the Epon Optical Light Expander (OLE) has been designed to improve the scalability and cost issues of EPON networks, adding, in this way, CWDM bandwidth enhancements without extra costs per subscriber. In this article, we empower the OLE with a new Adaptive Prediction Algorithm (APA) that allows for better performances in terms of per-user bandwidth assignment efficiency. Our algorithm shows an average packet delay that is 18% less than the standard Interleaved Polling Adaptive Control Protocol (IPACT) algorithm, simulated for medium traffic load conditions. © 2010 IEEE.
