Data synchronization method and apparatus for passive optical network, and data synchronization system

An electronic device, comprising:

• a processor;
• and
• a memory, configured to store instructions executable by the processor;
• wherein the processor is configured to perform the instructions to cause the electronic device to:
• perform an aligning and recovering operation comprising:
• performing synchronization alignment on multiple paths of first data signals, and recovering aligned multiple paths of first data signals into a path of a second data signal;
• perform passive optical network synchronization verification on the second data signal;
• and
• in a case where the second data signal does not pass the passive optical network synchronization verification, return to the aligning and recovering operation;
• or in a case where the second data signal passes the passive optical network synchronization verification, determine that the synchronization alignment is successful.

A data synchronization system, comprising:

• a data splitting apparatus, a first passive optical network device, a second passive optical network device, and a synchronization apparatus, that are connected in sequence;
• wherein the data splitting apparatus is configured to split a third data signal into multiple paths of first data signals, and transmit the multiple paths of first data signals to the synchronization apparatus via the first passive optical network device and the second passive optical network device;
• and
• the synchronization apparatus is configured to:
• perform an aligning and recovering operation comprising:
• performing synchronization alignment on multiple paths of first data signals, and recovering aligned multiple paths of first data signals into a path of a second data signal;
• perform passive optical network synchronization verification on the second data signal;
• and
• in a case where the second data signal does not pass the passive optical network synchronization verification, return to the aligning and recovering operation;
• or in a case where the second data signal passes the passive optical network synchronization verification, determine that the synchronization alignment is successful.
