The ZXA10 C320 Shelf Configuration includes the PRAM AC power card, which is exclusively installed into slot 3 of the ZTE ZXA10 C320 OLT; this card accepts 110 V or 220 V AC power input via its 1 dedicated AC power interface, features 1 battery interface and 1 temperature sensor interface to support storage battery connection and battery temperature monitoring respectively, and provides stable power supply to each card within the chassis, while also supporting DC power output for the heat exchanger and EPM in outdoor cabinets and being equipped with a convenient power-on switch for operational control.
1. Urban FTTH Deployment in Thailand
A Thai telecom operator deployed ZTE PRAM AC power boards in ZXA10 C320 OLTs for downtown Bangkok FTTH networks. The PRAM, installed in slot 3, supports 110V/220V AC input and features a backup battery interface, critical for stable power amid frequent grid fluctuations. It efficiently powers GPON service cards serving 3,000+ households, enabling 4K streaming and remote work. With hot-swap functionality and 320W max output, it ensured 99.9% power reliability, aligning with the operator’s network quality commitments.
2. Suburban Enterprise Zone in Italy
An Italian infrastructure firm adopted ZTE PRAM boards for ZXA10 C320 OLTs in a suburban enterprise park. The PRAM’s ability to convert AC to -48V DC powered multi-service cards (e.g., HUTQ, SCXM) for 50+ SMEs. Its temperature sensor interface and power-on switch simplified monitoring and management. Compact and energy-efficient, it fit small cabinet spaces and reduced operational costs, maintaining uninterrupted power for business-critical services like cloud access and video conferencing.
