1 General Provisions
1.0.1 A submarine communication system is the application of optical fiber cable communication technologies in the special environment of sea bottom.With over 30,000km of coastline,China has been expanding,along with further reform and opening-up,its marine exploration and development and utilization.The application of submarine optical fiber cable communication has been growing fast too.Besides telecommunication carriers,other industries and organizations also have growing demand for submarine cable communication.With this Code formulated,the design of submarine cable systems will be standardized to a higher level,the application of new technologies will be promoted and marine authorities’ approval of coastline planning and related projects will be based on a more rational and scientific basis.
1.0.2 Submarine cable projects that land in the Chinese mainland,extend to other countries,Hong Kong,Macao,or Taiwan,and have investors from foreign countries,Hong Kong,Macao,or Taiwan are referred to as cross-border submarine cable projects.Cross-border submarine optical fiber cable projects are mostly carried out by consortium.The design and construction of such projects shall follow the technical requirements and procedures of acceptance that are agreed upon by all investors.The technical requirements and project management model are different in some aspects from those of similar domestic projects.Therefore,this Code may serve as a reference for cross-border submarine cable projects.
Optical fiber cable projects that cross rivers and submarine optical and electrical hybrid cable projects may also use this Code as reference.
For extension and renovation projects,the renovated or extended parts may be consistent with the existing project.
Submarine cable line is the umbrella term of all submarine system elements in the cable route,including land cable,land cable joints and submerged plant.
1.0.3 Design of submarine cable systems shall be based on a comparison of multiple schemes so as to improve economic efficiency and reduce cost wherever possible.
1.0.4 Optical fiber submarine cable systems shall be built based on overall planning,joint construction,and resource sharing to meet the requirement of building a resource-saving and environmental-friendly society.
1.0.5 Equipment used in the design of submarine cable projects refers to materials and equipment that comply with relevant national technical standards or professional standards of competent authorities,and are manufactured on an industrial scale for commercial use.Experimental projects approved by competent authorities are not included.
1.0.6 For optical fiber submarine cable systems in areas where seismic fortification intensity is 7 degrees or above,the equipment shall meet seismic performance requirements for communication networks.
1.0.7 The design of a submarine cable project shall comply with the Law of the People’s Republic of China on the Administration of the Use of Sea Areas,Marine Environment Protection Law of the People’s Republic of China,Law of the People’s Republic of China on Environmental Impact Assessment,Regulations on Preventing and Controlling Damage to Marine Environment Caused by Marine Construction Projects,Provisions Governing the Laying of Submarine Cables and Pipelines,as well as other relevant laws and regulations of China on environmental protection,use of sea areas,and use of coastlines.For projects concerning national security,the Regulations on Compliance with National Defense Requirements in Transportation,Post and Telecommunication Infrastructure Construction shall also be complied with.
