Overview
See the eight-sided DVD system, which monitors vibrations at any point in the fibre fibre; it uses phase-time reflection technology, i.e. φ-OTDR technology; determines the location and other features of the cables that generate vibrations by detecting changes in returned light signals; extracts and AI self-learning algorithms through the feature library; and identifies and monitors events of various vibrations. The DVD system consists mainly of three components: vibrating monitoring mainframe, temperature sensor fibre, network management monitoring terminals. Based on client needs; multiple hosts can be used to network; monitoring coverage expanded
