Multi-layer fiber module with segmented storage and front access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fiber optic modules face challenges with disorganization and tangling of cables, inadequate slack storage, and difficult access due to back-entry configurations, which complicate maintenance and require multiple splice modules for different splicing scenarios.
Innovation Solution
A multi-layer splice module with a hinged transparent cover, separate layers for cable, splice, and pigtail storage, front-entry openings, and adaptable adapter plates to accommodate various adapter types, allowing for organized routing and storage of multi-fiber cables and facilitating easy maintenance within confined spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multi-fiber cable is routed to a splice module with back entry opening, then the module can store excess slack and facilitate splicing, but the cable may become disorganized and tangled within the module
Solution Approach 1:
The module is divided into multiple functional layers: a first layer for receiving and organizing the multi-fiber cable with separate channels for each fiber, a second layer for splicing operations, and a third layer for storing excess cable slack. This segmentation prevents cable tangling by providing dedicated pathways for each fiber while maintaining splicing functionality.
2Ease of manufacture
If a splice module is configured with back entry opening for cable access, then splicing can be performed, but maintenance becomes difficult due to confined access
Solution Approach 1:
The module provides dual access methods: traditional back entry for initial installation and a hinged cover on the front face for maintenance. This inversion of the typical access pattern allows technicians to perform maintenance from the front of the rack without requiring back access, significantly improving ease of repair while maintaining installation capabilities.
3Adaptability or versatility
If multiple splice modules are carried to a site to accommodate different splicing scenarios, then both single fiber and mass fusion splicing can be supported, but the device complexity and number of components increases
Solution Approach 1:
The module is designed with universal adaptability to perform multiple splicing functions: single fiber splicing, mass fusion splicing, and cable storage. The configurable adapter plate and multi-layer structure allow the same module to adapt to different splicing scenarios, eliminating the need to carry multiple specialized modules while maintaining full functionality.
4Ease of operation
If adapters are mounted with front opening configuration in telecommunications rack, then cable access is improved, but the splice module becomes difficult to install and maintain
Solution Approach 1:
The module utilizes the vertical dimension within the rack space by implementing a multi-layer stacked structure. Cables enter from the front and are routed vertically through dedicated channels to each layer, allowing front access while organizing cables in the vertical dimension to prevent tangling and simplify installation and maintenance.
