摘要： PROBLEM TO BE SOLVED: To provide an optical network system, an OLT, and an ONU capable of handling a signal requiring low delay and also capable of preventing a reduction in band utilization efficiency.SOLUTION: The optical network system uses an algorithm which, when transmitting an uplink signal from an ONU to an OLT, provides, within a band allocation cycle or in a specific discretionary band allocation cycle, a time slot (CAP) in which a signal is freely transmittable and a time (CFP) in which a band is dynamically allocated, allowing uplink transmission means to be multiply used. This algorithm enables low-delay and highly band utilization efficient uplink communication by performing communication of uplink data requiring low delay with low delay dispensing with REPORT/GATE or dispensing with a wait for time slot, and performing communication of other data not requiring low delay, by a DBA.
