GB／T 51154-2015 海底光缆工程设计规范（英文版）.pdf简介：

GB/T 51154-2015 "Underwater Optical Cable Engineering Design Specifications" (Chinese Version) is a technical standard specifically designed for the engineering design of underwater optical cable projects in China. This standard sets out guidelines, requirements, and best practices for the planning, installation, and maintenance of underwater optical cables used in telecommunications, data transmission, and other maritime applications.

The 2015 edition provides a comprehensive framework, covering aspects such as cable selection, route planning, installation techniques, environmental impact assessments, cable protection measures, and safety protocols. It also includes specifications for cable design, including minimum bending radii, water depth limits, and performance criteria under various environmental conditions.

In English, it would be titled as "Underwater Optical Fiber Cable Engineering Design Code" or similar, translating the technical terminology and concepts from Chinese to English. The PDF version of this standard would contain detailed technical specifications, drawings, and explanations, serving as a valuable resource for engineers, designers, and contractors involved in underwater optical cable projects.
