<p>A delay control method in the passive optical network, an optical line terminal and a passive optical network are provided. The delay control method in the passive optical network transmits the precision time protocol message in the direction of downlink, and the method includes: obtaining the buffer time of the precision time protocol message sent to the optical network unit (21); storing the precision time protocol message sent to the optical network unit, when the storing time being equal to the buffer time, sending the precision time protocol message to the optical network unit (22).</p> |
