Optical Line Terminal Power Adaptation for Mixed Power Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing PON networks face challenges in efficiently managing power supply to optical line terminals (OLTs) located remotely from the core network, as they often rely on limited and varied power sources such as wall power, coaxial cable power, and telecommunications power, requiring separate designs for each, which complicates inventory and installation.
Innovation Solution
A single optical line terminal design that can adapt to multiple power sources (wall power, coaxial cable power, and telecommunications power) by using an input power circuit topology that combines and selects the available power sources, ensuring a suitable DC voltage for operation, and includes a selection matrix for prioritization and reprogramming.

Engineering Contradiction Analysis
1Reliability
If separate OLT designs are used for each power source type, then each design can be optimized for its specific power source, but inventory complexity and installation difficulty increase
Solution Approach 1:
The patent implements a universal OLT platform that can operate with multiple power source types (wall power, coaxial cable power, telecommunications power) through a single device design. The power circuit includes multiple input circuits that can accept different power source configurations, and a power management system that automatically detects and adapts to the available power source, eliminating the need for separate designs for each power type while maintaining optimization for each source.
2Ease of operation
If multiple power source inputs are integrated into a single OLT design, then inventory complexity is reduced and installation is simplified, but the device must handle more varied power configurations
Solution Approach 1:
The power management system incorporates automatic detection and selection capabilities that allow the OLT to autonomously identify the connected power source type and configure its internal circuits accordingly. The system self-adjusts without requiring manual intervention or complex external configuration, simplifying installation while managing the complexity of handling multiple power configurations through intelligent automation.
3Device complexity
If a single universal OLT design is used, then inventory complexity is reduced, but the device may not be optimized for specific power source characteristics
Solution Approach 1:
The power circuit incorporates dynamic switching and adaptation mechanisms that adjust the operating parameters based on the detected power source type. The system can dynamically reconfigure its power processing characteristics to match the specific requirements of wall power, coaxial cable power, or telecommunications power inputs, maintaining optimal performance across different power sources while using a single universal hardware platform.
