Reliable fiber networks depend on more than optical equipment alone. For FTTH and other fiber deployments, Optical Line Terminals, or OLTs, are often at the center of the infrastructure. When those devices are installed in street cabinets, remote locations, or other demanding environments, power quality becomes a critical part of network performance.
Power outages, voltage spikes, and harsh environmental conditions can all impact uptime. To help keep fiber sites stable, power systems need to be reliable, scalable, and easy to manage remotely. That is where the 9dot nCore-Lite comes in. The nCore-Lite is a compact active power station designed in a single 1U rack unit, built to support smarter power management for telecom and fiber network environments.
Many OLT devices require a -48V power supply. The nCore-Lite supports this requirement through ADJ isolated output modules, which can be configured by software. By setting the voltage to 48V and reversing the connection terminals, operators can provide the stabilized -48V power required by compatible equipment.
This flexibility makes it easier to support fiber deployments where consistent, properly configured power is essential.
Even with its compact 1U form factor, nCore-Lite is built to support demanding power needs. According to 9dot, the system can deliver up to 1600W of total load through its ACDC and DCDC modules, with configurable ADJ module ports supporting up to 8A per output.
For optical nodes and remote telecom sites, this helps provide the capacity needed without taking up unnecessary rack space.
Fiber and telecom equipment is not always installed in climate-controlled spaces. Street cabinets, outdoor enclosures, and remote sites can expose equipment to wide temperature swings.
The nCore-Lite is designed with industrial-grade components and supports operation in ambient temperatures from -10°C to +55°C, or 14°F to 131°F. This makes it a practical option for deployments where environmental durability is just as important as power capacity.
Power continuity is one of the most important requirements for fiber infrastructure. The nCore-Lite includes a smart battery charger module that supports both lead-acid and lithium battery technologies, including LiFePO4. It is designed for instant online switchover to battery power during an outage.
The system also includes an Always On feature, which allows critical ports, such as those powering OLTs, to be prioritized. During a longer outage, secondary loads can be disabled automatically to help preserve power for the most important equipment.
Managing power equipment remotely can help reduce unnecessary truck rolls. The nCore-Lite supports remote control through a web interface, SNMP, and SSH. 9dot also notes that its dual-processor design allows the system to continue providing uninterrupted power during firmware updates.
For network operators managing distributed fiber sites, that remote visibility and control can make day-to-day maintenance more efficient.
As fiber networks continue to expand, power infrastructure needs to keep pace. The 9dot nCore-Lite offers a modular, compact, and remotely manageable option for supporting OLTs and other critical telecom equipment.
With support for -48V configurations, high-power output, battery backup, load prioritization, and remote management, nCore-Lite is built to help fiber networks maintain uptime in demanding environments.
