Scope

Optical fiber communication is an important direction for the development of communication technology and an advanced and practical means of communication for power system dedicated communication networks. The use of optical fiber communication in power systems has some advantages that other communication methods cannot match. In view of the increasing number of optical fiber circuits in the power system, this regulation is specially formulated in order to strengthen the management of optical fiber communication in the power system's dedicated communication network and serve the power grid more effectively. This regulation applies to directly buried optical cables, pipeline optical cables (including optical cables laid in cable trenches and corridors), overhead optical cables (including pole-mounted and self-supporting optical cables), overhead ground wire composite optical cables (OPGW), overhead ground wires Operation, maintenance and management of optical fiber communication circuits and equipment laid by wire-wound optical cables (GWWOP), overhead ground wires and bundled optical cables. The purpose of formulating this procedure is to use professional technical management methods to improve the operation and management level of optical fiber communications, ensure that operating equipment and circuit transmission performance meet technical standards, ensure personal and equipment safety, and provide power dispatching, relay protection, safety and stability control devices, Power grid dispatching automation and enterprise management and administrative management provide stable and reliable information transmission channels. This regulation is part of the electric power industry regulations and must be followed by all levels of electrical industry departments.
