We propose a new dynamic bandwidth allocation (DBA) method for long reach passive optical networks (PON) that can shorten upstream latency. In this method, the OLT allocates bandwidth to long-distance (up to 100 km) ONUs preliminarily and shortens the latency of long-distance optical network units (ONUs). This has no influence on the latency of short-distance ONUs if they coexist with long-distance ONUs. We show that this new DBA method achieves a smaller latency with long-distance ONUs than the conventional DBA technique, and that there is no influence on short-distance ONUs.
