Huawei MPLB Overview
Huawei MPLB (Main Processing Board) features central system control, service switching, and traffic aggregation for Huawei MA5800 OLTs, offering high reliability with active/standby control plane switchover, performance via load sharing (up to 200Gbps/slot), and advanced functions like ISSU (In-Service Software Upgrade) for zero downtime, SyncE/1588v2/1588ACR for precision timing, and multiple 10GE/GE uplink ports for flexible connectivity.
Product Features
- System Control: Acts as the core for system management, service switching, and traffic aggregation.
- High Availability: Supports active/standby failover for the control plane and ISSU for seamless software updates.
- Management Ports: Includes CON (serial), ETH (Ethernet), and ESC (environmental monitoring) for local/remote maintenance.
- Energy Efficiency: Power Saving: Contributes to the MA5800's overall energy-saving design through intelligent power management.
Application Scenarios
A regional telecom operator in Canada deployed MPLB uplink boards with MA5800-X7 OLTs to upgrade its suburban and SME network, covering 70,000 households and 12,000 small-to-medium enterprises across 9 cities. Each MPLB’s 4 GE ports aggregated traffic from GPON service boards, connecting OLTs to regional aggregation switches via 1Gbps copper links. The L2 VLAN function isolated residential and SME traffic, while QoS ensured priority for enterprise video conferencing and cloud access. With 40 MPLB boards deployed, the operator achieved 160Gbps total uplink capacity, meeting peak demands for 4K streaming and remote work—all at 35% lower costs than high-density alternatives, perfectly matching the region’s medium-scale bandwidth needs.
