1. An optical communication device that communicates with another optical communication device by using at least a time division multiplexing system, the optical communication device comprising:
a management control signal divider configured to divide a management control signal used for management and control, into a size falling within an assigned amount of transmission; and
a transmitter configured to transmit the divided management control signal, by superimposing the divided management control signal on a burst signal to be transmitted at an assigned transmission timing;
wherein the assigned amount of transmission is assigned from the another optical communication device to the optical communication device for transmission of a main signal.
