Embodiments of the present disclosure provides a visible light communication network. The visible light communication network includes a plurality of optical network nodes, any two optical network nodes of the plurality of optical network nodes are connected through an optical connection, the plurality of optical network nodes form at least one optical communication link, and each of the at least one optical communication link includes at least part of the plurality of optical network nodes. A first optical network node is configured to communicate an optical signal with an other optical network node through an optical connection between the first optical network node and the other optical network node, and the first optical network node is any optical network node in the optical communication link.
