Abstract
A method and a system for time synchronization based on an optical transmission network, and a storage medium. On a user terminal device side, a first identity is selected from one or more identities in a first identity set according to a preset selection rule, and added to a delay request packet to obtain a first delay request packet carrying the first identity. The first delay request packet is sent to a central office device through an optical splitter. In response to a received first delay request response packet carrying time synchronization information and the first identity, time synchronization is performed between a first user terminal device and the central office device based on the time synchronization information and the first identity.
