Application Scenarios
1. Telecom Network Reliability in Australia
A major Australian ISP deployed ZTE PRVR DC power boards on ZXA10 C650 OLTs across rural and urban exchange sites. Configured in dual-card load sharing mode (same input voltage), the PRVR boards delivered stable –48V DC power to PON service cards, supporting 60A maximum current per channel. Hot-swappable design allowed non-disruptive maintenance, while load sharing ensured uninterrupted broadband for 50,000+ users during peak hours. The deployment enhanced network uptime in remote areas prone to power fluctuations, aligning with the ISP’s 99.99% service reliability commitment.
2. 5G Backhaul Power Support in Germany
A German telecom adopted ZTE PRVR power boards on ZXA10 C600 OLTs to power 5G backhaul infrastructure in Berlin. The dual-card redundant setup (load sharing mode) provided consistent power to XGS-PON and combo service cards, including the GFTL 16-port XGS-PON board. With –48V DC input and 60A channel capacity, the PRVR boards supported high-bandwidth 5G data transmission, while hot-swapping minimized downtime during upgrades. This ensured reliable connectivity for enterprise cloud services and residential 10Gbps broadband, supporting Germany’s digital infrastructure expansion.
FAQ
