FIELD: physics, computer engineering.
SUBSTANCE: invention relates to means of constructing digital networks. The network consists of N series-connected routing switching nodes, which can be closed into a ring, with routing division, which can be carried out electronically in routers, and switching, which can be carried out optically in photonic switches. Use of the present fibre-optic network enables to construct ring and linear packet switched telecommunication networks using the existing SDH network structure by replacing terminal multiplexers with a switching and routing node.
EFFECT: fewer electronic-optical conversions in the system, which reduces distortions caused by said conversions.
