GB/T 17881-1999
ActiveTechnical specifications of SDH transmission interface for broadcasting and television optical backbone network
广播电视光缆干线同步数字体系(SDH)传输接口技术规范
Application Summary AI generated
This standard specifies the technical requirements for Synchronous Digital Hierarchy (SDH) transmission interfaces used in broadcasting and television optical backbone networks. It is applied to ensure interoperability and signal quality in the long-distance, high-capacity fiber optic transmission of broadcast and television signals. The standard is primarily used by network operators and equipment manufacturers for designing, testing, and maintaining SDH-based trunk lines in China's radio and TV distribution systems.
