Fiber Shuffle Box Centralized Splitting for Cross-Manufacturer Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reconfigurable optical add-drop multiplexers face challenges in achieving compatibility and reliability due to the use of private connection protocols between devices from different manufacturers, leading to higher costs and complexity.
Innovation Solution
Incorporating a splitter within the fiber shuffle box and using standard LC splices for connections between the line direction unit and local add-drop unit, allowing for heterogeneous integration and reducing the need for additional splitters in the local add-drop unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a 1: n splitter is configured in the local add-drop unit to connect wavelength to all directions, then the connection capability is improved, but the device complexity and cost increase
Solution Approach 1:
The patent extracts the splitter function from the local add-drop unit and relocates it to the fiber shuffle box. This removes the need for each local add-drop unit to have its own 1: n splitter, thereby reducing device complexity while maintaining the ability to connect wavelengths to all directions through the centralized splitter in the fiber shuffle box
Solution Approach 2:
The fiber shuffle box is designed to perform multiple functions: it acts as both a fiber routing switch and a centralized splitting node. By integrating the splitter into the fiber shuffle box, the system achieves multi-functionality where a single component serves both routing and signal distribution purposes, reducing overall system complexity
2Reliability
If private connection protocols are used between devices from different manufacturers, then device-specific optimization is achieved, but compatibility and heterogeneity are reduced
Solution Approach 1:
The patent adopts homogeneous standard LC connection interfaces and protocols for all connections between the fiber shuffle box and local add-drop units. This standardization ensures that devices from different manufacturers can be interconnected without requiring private or proprietary connection methods, thereby achieving both compatibility and reliable communication through well-established standards
3Adaptability or versatility
If each local add-drop unit includes its own splitter, then signal distribution capability is improved, but the number of components and cost increase
Solution Approach 1:
The patent merges all splitter functions into a single centralized splitter located in the fiber shuffle box, rather than having separate splitters in each local add-drop unit. This consolidation reduces the total number of splitter components while maintaining full signal distribution capability, as the centralized splitter can distribute signals to all required directions through the fiber shuffle box's routing functionality

Implementation Method 1
the splitter divides the compensated optical wave signal into N uplink signals and sends the N uplink signals to corresponding line direction units
Implementation Method 2
performing multiplexing on optical waves to be sent by using a multiplexer to obtain an optical wave signal
Implementation Method 3
performing multiplexing loss compensation processing on the optical wave signal by using an uplink power amplify to obtain a compensated optical wave signal
