Splice Module Integrated Overlength Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fiber optic distribution systems require a significant amount of space due to the need for separate compartments for excess fiber lengths, which limits packing density and increases mechanical stress on cables, especially in data centers with expanding network demands.
Innovation Solution
A splicing module with integrated excess length management using flexible protective hoses that act as both a protective sleeve and a bend radius limiter, allowing for controlled storage and retrieval of loose tubes within the module, eliminating the need for an additional height unit for excess length storage and enabling higher packing density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate compartments for excess fiber lengths are used, then fiber protection and handling are improved, but space requirement and device complexity increase
Solution Approach 1:
The patent combines the excess length storage function with the splicing module housing by integrating a reel mechanism directly into the module. The reel is mounted within the splicing module housing, allowing excess fiber to be wound and stored compactly within the same space that previously required separate overlength drawers or compartments. This merging eliminates the need for additional height units while maintaining fiber protection capabilities.
Solution Approach 2:
The patent implements nesting by placing the reel mechanism inside the splicing module housing. The reel is positioned such that it fits within the existing structural boundaries of the module, with the fiber winding around the reel core and the reel itself nested within the housing cavity. This nested arrangement allows the excess length management system to occupy minimal additional space while providing comprehensive fiber protection.
2Productivity
If more splice modules are accommodated per subrack, then packing density is improved, but mechanical stress on fiber optic cables increases
Solution Approach 1:
The patent introduces a dynamic reel mechanism that allows the excess fiber length to be actively managed as modules are added or removed from the subrack. The reel can rotate to pay out or wind in fiber as needed, dynamically adapting to changes in the system configuration. This dynamic capability prevents mechanical stress that would occur with static, fixed-length fiber arrangements, enabling higher packing density without compromising cable integrity.
Solution Approach 2:
The patent changes the parameter of fiber length management from fixed to variable by implementing a reel mechanism. The effective fiber length available to each module can be adjusted by rotating the reel, allowing the system to accommodate varying numbers of splice modules per subrack. This parameter change enables the system to optimize packing density while maintaining appropriate fiber tension and minimizing mechanical stress on the cables.
3Ease of operation
If excess length is stored outside the splicing module, then module removal is simplified, but space requirement and device complexity increase
Solution Approach 1:
The patent merges the excess length storage function with the splicing module by integrating a reel mechanism directly into the module housing. The reel is mounted within the module itself, and the fiber is routed through the module structure. This integration maintains ease of module removal and installation while eliminating the need for separate external storage compartments, thereby reducing overall system complexity.
Solution Approach 2:
The reel mechanism is designed to be self-contained within the splicing module, with the fiber automatically winding onto or unwinding from the reel as the module is installed or removed. This self-service design eliminates the need for manual fiber management or external assistance during module handling, maintaining operational simplicity while integrating the storage function within the module boundaries.
