PRODUCT IDENTIFICATION

The H901NXED (Model: H901NXED) is a high-density, 8-port upstream interface board engineered exclusively for the Huawei SmartAX MA5800 series multi-service access platforms. As a critical component for next-generation fiber-to-the-home (FTTH) and business access networks, this card provides 10 Gigabit Ethernet (10GE) and Gigabit Ethernet (GE) optical uplink interfaces. It is designed to meet the rigorous demands of carrier-grade operations, enabling seamless aggregation and high-bandwidth upstream transmission for XG-PON, XGS-PON, and GPON access networks .

CORE INTERNAL TOPOLOGY & HARDWARE ARCHITECTURE

The H901NXED is built on a distributed forwarding architecture with a non-blocking switching fabric, providing up to 80 Gbit/s of non-converged upstream bandwidth . Its hardware design emphasizes both performance and resilience. The board is hot-swappable, supporting online insertion and removal (OIR) without impacting system operation, a critical feature for minimizing downtime during network expansion or maintenance .

It features a substantial MAC address table size of 262,143 entries, ensuring efficient handling of large-scale user equipment in dense access environments . The board's design supports advanced synchronization features, including IEEE 1588v2 (Precision Time Protocol) and Synchronous Ethernet (SyncE), which are essential for delivering high-quality time and frequency synchronization for mobile backhaul and other latency-sensitive services .
