ZTE PRAF Overview
The PRAF is a ZTE ZXA10 C620-specific 110-220V AC power board that supports 220V/110V AC input to supply power to the cards of the ZXA10 C620, and it features a backup battery interface (including a battery temperature sensor interface) as well as a power input control switch; in contrast, the PRVR/PRVR(C) is a DC power board designed for the ZXA10 C600/C650 that provides one –48V DC input interface with each channel supporting a maximum current of 60A and supports hot swapping, while the PRSF is a DC power board for the ZXA10 C620 that offers one –48V/–60V DC input interface with a maximum supported current of 15A; additionally, the ZXA10 C600/C650 supports two power cards that operate in load sharing mode if their input voltages are the same, and the ZXA10 C620 supports two DC power supply cards (e.g., PRSF) or one AC power supply card (i.e., PRAF) for flexible power configuration.
Product Features
- Power Conversion: Converts 220V/110V AC input to the 48V DC required by the OLT chassis and boards.
- Hot-Swappable: Allows for replacement without interrupting OLT operation, ensuring high availability.
- Reliable Power: Provides stable power for high-density data traffic and performance.
- Environmental Robustness: Designed to operate in extreme conditions (freezing, scorching, damp, dry).
- Backup Support: Includes interfaces for backup batteries and temperature sensors.
- OLT Integration: Works with ZTE C300, C320, and C620 OLT platforms, supporting various PON technologies (GPON, 10G PON).
Application Scenarios
1. Urban FTTH Reliability in Mexico
A major Mexican ISP deployed ZTE PRAF AC power boards on ZXA10 C620 OLTs for dense urban FTTH networks in Mexico City. The 110V/220V AC input compatibility integrated seamlessly with local grid infrastructure, while the backup battery interface (with temperature sensor) ensured uninterrupted service during frequent power sags. The power input control switch simplified on-site management, and the board’s robust design supported 24/7 operation for 15,000+ residential users. This deployment aligned with the ISP’s goal of 99.99% service uptime for high-bandwidth applications like streaming and remote work.
2. Rural Telecom Resilience in South Africa
A South African telecom adopted ZTE PRAF boards for ZXA10 C620 OLTs in underserved rural regions. Paired with solar hybrid battery systems, the PRAF’s backup battery interface provided critical power redundancy in areas with unstable grid access. Its 110V/220V input flexibility adapted to local power conditions, while the temperature sensor protected batteries from extreme heat. The board powered GPON service cards, delivering reliable broadband to rural schools and businesses, supporting the country’s digital inclusion initiatives with minimal maintenance downtime.
