ZTE's PRWG is a DC Power Board for its ZXA10 C300/C350 Optical Line Terminals (OLTs), offering features like -48V/-60V DC input, redundancy (1:1 protection), load balancing, and robust power filtering, ensuring high reliability and eco-friendly operation for FTTH networks, supporting various PON technologies (GPON, EPON) with seamless integration and automatic ONU configuration for efficient service deployment.
Product Features
Power Filtering: Includes input power filtering and current limitation for stable power delivery.
DC Power Input: Accepts -48V or -60V DC input, with options for AC input on some platforms (C300).
Redundancy: Supports 1:1 power redundancy for high availability, ensuring continuous operation.
Load Balancing: When two power cards are used, they share the load equally for better efficiency.
Power Filtering: Includes input power filtering and current limitation for stable power delivery.
Automated Service: Simplifies provisioning with automatic service configuration and plug-and-play ONU access.
Application Scenarios
1. FTTH Network in Remote Areas of South Africa
A South African regional telecom operator deployed ZTE PRWG DC power boards with ZXA10 C300 OLTs for rural FTTH projects. The PRWG, supporting -48V DC input and 30A max current, adapted well to unstable rural power grids. Its dual-card load-balance mode ensured continuous power supply for OLTs serving 1,800+ scattered households. With compact design and 4W low power consumption, it fit small outdoor cabinets and reduced energy costs, maintaining 99.85% power reliability to bridge the rural digital divide.
2. Smart Campus Infrastructure in Singapore
A top Singaporean university adopted ZTE PRWG boards in ZXA10 C350 OLTs for its smart campus network. The PRWG provided stable power for high-density service cards (e.g., SCXL, HUVQ) supporting 10,000+ users. Its real-time monitoring and alarm functions enabled proactive maintenance, while hot-swappable design allowed zero-downtime repairs—critical for 24/7 campus services. Paired with ZTE’s energy-saving solution, it cut campus network power costs by 12%, aligning with the university’s sustainability goals.
