Huawei MPSA Overview
Huawei MPSA (H901MPSA) is a main control board for the SmartAX MA5800 OLT, featuring a distributed architecture for high throughput (e.g., 80Gbps/slot), massive subscriber/MAC/ARP capacity, advanced service support (like 4K/8K video, Flex-PON), ISSU for seamless upgrades, and energy-saving functions, acting as the core for control and switching in next-gen broadband networks.
Product Features
- Core Function: Central control and service switching for MA5800 OLTs.
- Distributed Architecture: Separates control and forwarding planes for high performance (e.g., 200Gbps per slot in newer platforms).
- High Capacity: Supports a large number of subscribers (e.g., 4096 ONTs), MAC addresses (e.g., 262,143), and ARP/routing entries (e.g., 65,536).
- Performance: Handles significant bandwidth (e.g., 80Gbps/slot in load sharing mode).
- Service Support: Optimized for next-gen services like 4K/8K video, VR, and supports unified access for fiber, copper, and cable.
- PON Evolution: Supports Flex-PON for smooth upgrades from GPON to XG(S)-PON.
Application Scenarios
A regional telecom operator in Southeast Asia deployed MPSA uplink boards with MA5800-X7 OLTs to upgrade its suburban and small enterprise network, covering 60,000 households and 8,000 small-to-medium enterprises (SMEs) across 8 cities. Each MPSA’s 4 10GE SFP+ ports aggregated traffic from XGS-PON/GPON service boards, connecting OLTs to regional aggregation switches via 10Gbps fiber links. The L2 VLAN function isolated residential and SME traffic, while QoS ensured priority for enterprise data services. With 35 MPSA boards deployed, the operator achieved 1.4Tbps total uplink capacity, meeting peak demands for 4K streaming, remote work, and SME cloud access—all at 30% lower procurement costs compared to high-density alternatives.
