The invention discloses a dynamic bandwidth allocation algorithm applied to an OFDM-PON (Orthogonal Frequency Division Multiplexing-Passive Optical Network) system and belongs to optical fiber communication systems. The invention utilizes an interruption application response method to realize the bandwidth request and allocation; a plurality of subcarriers in the system are divided into three parts, namely, a communication channel control part, an ONU (Optical Network Unit) default bandwidth part and a part stored in a dynamic pool; when the load on the link is light, each ONU compares respective local flow with local threshold value so as to decide whether an interruption application for extra bandwidth is started; and when the load on the link is heavy, an OLT (Optical Line Terminal) allocates the surplus subcarriers based on the requiring ratio of the ONUs under the condition that the rated bandwidth of the ONUs is met firstly, so as to realize dynamic allocation. The invention ensures low time delay and low package loss rate of a high priority service, also performs bandwidth allocation as required, and can meet the equal allocation between the ONUs and the equal-level priority service when the load of link service flow is heavy.
