ABSTRACT:
A bandwidth allocation equipment in an optical line terminal, which allocates bandwidth for data to be transmitted from optical network units through an optical splitter, includes a transmit/receive unit and bandwidth allocation units. The transmit/receive unit receives an output request for requesting bandwidth allocation, and sends back a signal sending permission to the respective optical network units for specifying bandwidth to be allowed for transmitting the data in each service cycle. The bandwidth allocation units are connected to one another in a ring. Each bandwidth allocation unit is provided with corresponding to the optical network unit, and outputs the signal sending permission from the bandwidth allocation unit that has performed the last bandwidth allocation processing in the ring connection. The transmit/receive unit specifies the bandwidth allocation unit that performs the first bandwidth allocation processing by shifting one by one for each of the service cycles.
