Abstract

The disclosure provides a monitoring control device and an optical power supply system in which a system capable of remotely controlling many optical power supply type optical nodes can be economically constructed. A monitoring control device according to the present disclosure includes control means for executing power supply and power supply time allocation for selecting a control target optical node based on the amount of stored energy of a plurality of optical nodes. According to the present disclosure, in a system that includes a monitoring control device installed in a power supply environment and one or a plurality of remotely arranged optical line switching nodes, optical power supply and control of a plurality of optical switches included in the nodes and management of an amount of stored power can be simultaneously implemented with a single laser. Thus, it is possible to provide an economical optical line switching node system.
