1 Scope

GB/T 46463-2025 is the Chinese national standard covering testing XGS-PON kit - the optical budget and receiver sensitivity, the ranging and burst mode timing that make a shared fibre work, the dynamic bandwidth allocation, the coexistence with the GPON already on the same fibre, and the management interface. At 35,000 words. First edition, under the Ministry of Industry and Information Technology. In force from 1 February 2026. Issued on 31 October 2025, it has been in force since 1 February 2026.

This document describes the interfaces between the central office equipment (OLT) and the user-side equipment (ONU) of a 10Gbit/s symmetric passive optical network (XGS-PON). Testing methods for functionality, performance, operation, management, and maintenance. This document applies to the research, development, production, and testing of XGS-PON equipment in public telecommunications network environments. It can also be used as a reference for private telecommunications networks.
