ZTE PRSF Overview
The PRSF is a ZXA10 power board originally specified for ZTE OLT ZXA10 C600/C650, though it primarily provides one –48V/–60V DC input interface to supply power to cards of the ZXA10 C620 with a maximum supported current of 15A; in contrast, the PRVR/PRVR(C) is a dedicated power board for ZXA10 C600/C650 that offers one –48V DC input interface with each channel supporting a maximum current of 60A and supports hot swapping, while the PRAF is an AC power board for ZXA10 C620 that supports 220V/110V AC input, a backup battery interface (including a battery temperature sensor interface), and a power input control switch; 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 or one AC power supply card for flexible power configuration.

Application Scenarios
1. Rural Broadband Power Support in Canada
A Canadian telecom deployed ZTE PRSF power boards on ZXA10 C620 OLTs for rural broadband expansion in Alberta. The board’s dual –48V/–60V DC input compatibility adapted to regional power infrastructure, delivering 15A max current to power PON service cards. Configured in dual DC card redundancy, it ensured uninterrupted connectivity for remote households relying on broadband for work and education. Its compact design fit pole-mounted enclosures, while stable power output supported reliable FTTH services in harsh weather, aligning with the operator’s universal access goals.
2. Enterprise & Residential Convergence in France
An ISP in Lyon adopted ZTE PRSF boards for ZXA10 C620 OLTs in mixed-use urban developments. The 15A current capacity powered GPON/XG-PON combo cards, supporting both residential broadband and small business connectivity. Paired with PRAF AC power cards for redundancy, the PRSF ensured 24/7 service availability—critical for retail POS systems and home streaming. Its flexible voltage input simplified integration with existing DC power systems, reducing deployment costs while maintaining high reliability for 10,000+ users across offices and apartments.
FAQ
Q: What is the ZTE PRSF Board?
A: It is a DC power board designed for ZTE ZXA10 C620 OLTs, providing –48V/–60V DC input and 15A maximum current to power OLT service cards reliably.
Q: Which OLT models is the PRSF compatible with?
A: The PRSF is specifically compatible with ZXA10 C620 OLTs; it is not designed for C600/C650 models (use PRVR/PRVR(C) for those).
Q: What is the maximum current supported by the PRSF Board?
A: It supports a maximum current of 15A, suitable for powering service cards in medium-scale C620 OLT deployments.
Q: How does the PRSF differ from the PRVR power board?
A: PRSF powers C620 (–48V/–60V, 15A), while PRVR is for C600/C650 (–48V, 60A) with hot-swapping and load sharing features.
Q: What is the warranty period?
A: 12-month warranty covering manufacturing defects.
Q: What is the lead time for orders?
A: 3-5 days for samples/small orders.
