Deploying fiber optic repeaters in rural areas often comes with a significant challenge: power supply. To ensure optimal mobile signal coverage, the near-end unit of a fiber optic repeater is typically installed in locations where power infrastructure is lacking, such as mountains, deserts, and farmlands. To address this issue, solar power systems are commonly used to provide reliable electricity.

Lintratek has recently launched a solar power system specifically designed for fiber optic repeaters. The R&D team has optimized the system to offer flexible power solutions with different output capacities. This adaptability allows solar power configurations to be tailored to the power consumption needs of various fiber optic repeaters and mobile signal boosters, providing a cost-effective solution that helps customers save on expenses.
Solar Power System for Fiber Optic Repeaters and Mobile Signal Boosters
Integrated Lithium Battery Storage and Control System
200W Solar Panel
1. Solar Panels (PV Modules): Made from high-efficiency monocrystalline silicon, these panels achieve a solar-to-electric conversion rate of over 22%. Available power ratings include 80W, 120W, 150W, 180W, 200W, 240W, 300W, 360W, 400W, and even 600W to accommodate various power demands.
2. Solar Mounting Structure: The integrated mounting frame requires no installation, is lightweight, and features galvanized treatment for long-term durability.
3. Battery Storage: Batteries are a crucial part of the solar power system, storing energy generated by the solar panels for use during nighttime or cloudy days.
- Types of Solar Batteries:
- Lead-acid battery
- Lithium-ion battery
- Nickel-cadmium battery
Battery of Solar Power System
- Key Battery Parameters:
- Capacity (Ah): Determines the amount of energy stored.
- Voltage (V): Must match the system requirements.
- Cycle Life: The number of charge-discharge cycles the battery can sustain.
- Depth of Discharge (DoD): Affects battery lifespan.
- Integrated Lithium Iron Phosphate (LiFePO4) Battery: Features an advanced storage and control system, providing comprehensive protection to ensure stable and efficient long-term operation.
4. Charge Controllers:
- PWM (Pulse Width Modulation) Controller: A simple, cost-effective solution for small systems. Many low-power solar power systems integrate this controller directly into the battery.
- MPPT (Maximum Power Point Tracking) Controller: More efficient, ideal for larger systems, but comes at a higher cost.
5. Inverter: Converts the battery’s DC power into AC power for industrial or household use. Available in pure sine wave and modified sinewave types. The inverter should be sized with a 20%-30% power margin above the total load consumption.
Case Study: 5W Dual-Band Fiber Optic Repeater with Solar Power Supply
For a fiber optic repeater with a peak power consumption of 80W, operating 24 hours a day, the solar power system was designed as follows:
1. Energy Consumption Calculation:
- Peak power consumption: 80W × 24h = 1920Wh (1.92kWh/day)
- Solar panel power calculation based on an average of 4 hours of sunlight per day.
2. Solar Panels Selection:
- To generate at least 1.92kWh per day, three 200W solar panels were selected.
3. Battery Storage Calculation:
- To ensure continuous operation during cloudy days, a backup of three days’ energy (5.76kWh) was required.
- A 48V 150Ah lithium battery was chosen. Alternatively, four 12V 150Ah batteries in parallel could be used.
4. Charge Controller & Inverter:
- A 48V MPPT charge controller was selected to optimize charging efficiency.
5. Mounting Structure and Cables:
- Lintratek recommended a fully integrated system with appropriate wiring.
Estimated cost: approximately $400
Conclusion
For those looking to deploy fiber optic repeaters in rural areas with limited power infrastructure, a well-designed solar power system provides a sustainable and cost-effective solution. Lintratek’s solar-powered solution ensures reliable mobile signal coverage without reliance on traditional grid power.
