Abstract
A time synchronization method for a passive optical network, and an electronic device and a storage medium are disclosed. The method may include acquiring a first response time from a first optical network unit (ONU); performing a ranging calculation to the first ONU to acquire a first equalization time delay; generating an equalization delay configuration message according to the first response time and the first equalization delay; and sending the equalization delay configuration message to a second ONU to configure a second equalization delay for the second ONU; where the first ONU and the second ONU access the same branch optical fiber.
Claims19
A method for time synchronization in a passive optical network (PON), which is applied to an optical line terminal (OLT), the method comprising,
- acquiring a first response time from a first optical network unit (ONU);
- performing a ranging calculation to the first ONU to acquire a first equalization time delay;
- generating an equalization delay configuration message according to the first response time and the first equalization delay;
- and
- sending the equalization delay configuration message to a second ONU to configure a second equalization delay for the second ONU;
- wherein, the first ONU and the second ONU access a same branch optical fiber;
