Huawei MPWC Overview
The Huawei MPWC is a Dual DC Power Supply Board for Huawei OLTs (like the MA5608T), providing reliable -48V power with features like dual input for redundancy, filtering/current limiting, fault detection (undervoltage, supply faults), overload/short-circuit protection, and alarm reporting, ensuring continuous operation for broadband access devices in telecom networks.
Product Features
- Dual DC Inputs: Uses two -48V DC inputs for mutual backup, enhancing reliability.
- Power Filtering & Limiting: Filters input power and limits current to protect connected equipment.
- Voltage Range: Operates within a wide input range of -38.4V to -72V DC.
- Protection: Includes overload and short-circuit protection.
- Alarm Reporting: Detects and reports undervoltage, power supply faults, and fuse breakage.
- Status Indication: Provides visual indication of power status.
Application Scenarios
Smart City Outdoor Surveillance & IoT Access for European Operators
A telecom operator in Western Europe provided smart city solutions for a major metropolis, requiring access to 200 high-power PTZ surveillance cameras (50W each) and 80 outdoor wireless APs (30W each). It deployed Huawei MA5800 OLTs with MPWC boards: each OLT was configured with 15 MPWC boards (240 ports total) to connect the devices. The MPWC’s 60W PoE++ ports directly powered the PTZ cameras (no external power cabinets), and 1000M adaptive speed ensured smooth transmission of 4K surveillance footage. Its -40°C~+65°C design adapted to the city’s extreme weather (winter low -15°C, summer high 38°C), and surge protection prevented damage from lightning. Remote O&M allowed real-time monitoring of port power and device connectivity, reducing deployment costs by 40% and achieving 99.99% service availability.
