Huawei MPWD Overview
Huawei MPWD (Modular Power Module Wide-range//DC) power boards are essential components for Huawei's access network devices (like MA5608T OLTs), providing reliable AC/DC power with extensive protection (overcurrent, overvoltage, short circuit, over-temp), battery backup management, and environment monitoring, ensuring stable operation for broadband and voice services with features like input filtering, fault detection, and alarm reporting, supporting both AC input and -48V DC battery backup.
Product Features
- Power Conversion & Supply: Converts AC input (100V-240V) into stable DC power for the OLT system, with rated outputs (e.g., 400W).
- Comprehensive Protection: Built-in safeguards against overcurrent, output overvoltage, short circuits, and over-temperature conditions.
- Battery Management: Supports lead-acid battery backup, offering low voltage disconnection, charge/discharge management, and battery temperature sensing.
- Monitoring & Alarms: Includes a monitoring unit for power system status, battery health, and environmental factors (like temperature), reporting faults and alarms.
- Input Flexibility: Handles single-phase three-wire AC power and can connect to -48V DC backup.
Fault Detection: Detects input power issues and fuse breaks, reporting these as alarms.
Application Scenarios
Rural FTTH Network OLT Power Supply for African Operators
A telecom operator in East Africa deployed Huawei MA5608T OLTs with MPWD power boards to support FTTH services for 30,000 rural households. Each OLT was configured with 1 MPWD board and 2 lead-acid batteries (backup). The MPWD’s 400W output powered the OLT chassis and 8 GPON service boards, while battery backup ensured 4-hour uninterrupted service during frequent rural power outages. Its -40°C~+65°C design adapted to the region’s extreme temperature swings (10°C at night, 40°C during the day), and comprehensive protection prevented damage from voltage fluctuations. The monitoring unit allowed remote tracking of battery status, reducing on-site maintenance by 40% and achieving 99.99% OLT availability.
