DATA COMMUNICATION METHOD IN OPTICAL NETWORK SYSTEM, OPTICAL NETWORK UNIT AND SYSTEM

摘要

The present invention provides a data communication method, where the method includes: receiving, through a first port of a first optical network unit, a first message sent by a first optical line terminal, where the first message is used to instruct the first optical network unit to switch to the second port from the first port; and after the first optical network unit switches to the second port from the first port according to the first message, performing data communication with a second optical line terminal through the second port. It is ensured that switchover time between the OLTs is within 50 ms, and reliability of data communication is further improved.
