GB／T 51126-2015 波分复用（WDM）光纤传输系统工程验收规范 （英文版）.pdf简介：

GB/T 51126-2015, "Optical WDM Fiber Transmission System Engineering Acceptance Specifications", is a technical standard in China that specifies the requirements and procedures for the acceptance testing of Wavelength Division Multiplexing (WDM) fiber transmission systems. This standard is aimed at ensuring the quality and reliability of such systems in engineering projects, which are widely used in telecommunications, data transmission, and other industries.

It covers various aspects including system design, installation, testing, and documentation, with a focus on performance parameters, system functionality, and safety measures. The document provides guidelines for engineers, technicians, and other stakeholders to ensure that the installed WDM systems conform to the established technical standards and specifications.

The PDF version of this standard likely contains detailed technical specifications, test methods, acceptance criteria, and best practices, making it a key reference for professionals working in the field of optical fiber communication systems. Since it is in Chinese, an English translation or summary may not be readily available, but you can find the original Chinese version for reference or seek a professional translation service if needed.
