Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical fiber communication networks face challenges in adapting to varying user requirements due to a lack of optical splitters with variable splitting ratios, making it difficult to achieve mobility and flexibility in terminal user access.
Innovation Solution
A cascaded optical splitter system is implemented, comprising multiple splitting units, including wavelength-sensitive and ordinary optical splitters, which allow for adjustable splitting ratios by regulating optical signals based on wavelengths or wavebands, enabling controllable and adaptable splitting ratios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed optical splitter is used in the ODN, then the network structure is simple and easy to implement, but the splitting ratio cannot be changed once selected, making it difficult to achieve adaptability to terminal user mobility
Solution Approach 1:
The patent applies the dynamics principle by transforming the static, fixed splitting ratio of traditional optical splitters into a dynamic, adjustable system. The optical splitter can now change its splitting ratio based on terminal user mobility requirements, allowing the network to adapt to varying user demands without requiring complete network reconfiguration. This dynamic capability enables the same optical access network to serve diverse user requirements efficiently.
Solution Approach 2:
The patent segments the optical splitting function into multiple adjustable stages or configurations. Instead of a single fixed splitter, the system divides the splitting function across multiple controllable units, allowing independent adjustment of splitting ratios for different user groups or time periods. This segmentation enables flexible adaptation to terminal user mobility while maintaining manageable system complexity.
2Adaptability or versatility
If the ODN is fixed to serve specific users, then the network configuration is stable, but it cannot accommodate diverse user requirements when terminal users move or when networks are integrated
Solution Approach 1:
The patent implements parameter changes by enabling the optical splitter's key parameter (splitting ratio) to be dynamically adjusted. Instead of fixing the network configuration to specific users, the system can modify splitting ratios to accommodate diverse user requirements arising from terminal mobility or network integration. This parameter flexibility maintains network stability while enhancing adaptability to changing user demands.
3Adaptability or versatility
If three networks (mobile communication, telecommunication, broadcast and television) are integrated into one optical access network, then resource utilization is improved, but user diversity increases and makes it difficult to meet varying user requirements with a fixed ODN
Solution Approach 1:
The patent applies universality by designing an optical splitter that can serve multiple network types (mobile communication, telecommunication, broadcast and television) with a single device. The splitter's ability to dynamically adjust splitting ratios allows it to handle diverse user requirements from different network services uniformly, eliminating the need for separate fixed splitters for each network type and reducing overall system complexity despite the multi-functional requirement.
