Disclosed are a wavelength multi-casting method and device in a multi-ring network, and more particularly, a wavelength multi-casting method and device in a multi-ring network capable of configuring an economical network. The wavelength multi-casting method in the multi-ring network according to the exemplary embodiment of the present invention includes: receiving, by one node, optical signals from other nodes within a ring network to which the node belongs; and multi-casting, by the node, an optical wavelength to neighboring nodes by a scheme of dropping and continuing the transmitted optical signals.
