Fiber Networks Deserve Smarter Power

In the world of telecommunications, the reliability of a fiber-optic network (FTTH) depends directly on the heart of the infrastructure: the OLTs (Optical Line Terminals).

But what happens when these devices, often installed in street cabinets or remote sites, face power outages, voltage spikes, or harsh environmental conditions?

To keep the connection stable at all times, the power supply must be smart, scalable, and robust.
This is where 9dot’s nCore-Lite comes in—a compact, active power station housed in a single 1U rack unit.

How can you ensure absolute uptime for your fiber-optic OLTs?

The answer is simple: nCore-Lite by 9dot.

Here’s how nCore-Lite can transform power management at your fiber sites:

1.🔋 Total flexibility for -48V: OLT devices frequently require a -48V power supply. nCore-Lite handles this scenario perfectly: by using the ADJ isolated output modules, you can set the voltage to 48V via software and, simply by reversing the connection terminals, obtain the clean, stabilized -48V power required by the equipment.

2.⚡High-power management: Despite its compact size, nCore-Lite can deliver up to 1600W of total load through its ACDC and DCDC modules. The configurable ports of the ADJ modules support up to 8A per output, ensuring sufficient power even for the most demanding optical nodes.

3.🛡️Durability in extreme environments: Telecommunications sites are not always temperature-controlled environments. nCore-Lite is designed with industrial-grade components capable of operating optimally in ambient temperatures ranging from -10°C to +55°C (14 °F - 131 °F) , making it reliable even in the harshest climatic conditions.

4. 🔋Operational Continuity and Proactive Mode: The integrated smart battery charger module supports both lead-acid and lithium technologies (such as LiFePO4) and ensures an instantaneous, uninterrupted switchover to battery power (“Instant online”). Using the Always On feature, you can assign the highest priority to the ports powering the OLTs: in the event of a prolonged power outage, the system will automatically disable secondary loads to maximize the survival of critical devices.

5. 💻 Remote Control and Security: Avoid costly on-site visits. nCore-Lite offers full remote control via a web interface, SNMP (completely redesigned), and SSH. Additionally, the dual-processor design ensures the system continues to provide uninterrupted power even during firmware updates.
