Field Installable Optical Module Cable Adaptor Case
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing patch and splice cassette modules are not space-efficient, prone to fiber damage, and have cumbersome fiber management issues due to moving parts, limited cable entry/access, and poor handling of ribbon fibers, requiring time-consuming installation and multiple consumable items.
Innovation Solution
A cable adaptor case with a cable tray, adaptor tray, splice holders, and removable breakout portions, featuring secure cable clips and snap-in/snap-out splice holders to prevent fiber damage and simplify installation, while allowing flexible cable entry and efficient ribbon fiber management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a stationary splice sleeve holder is used, then the module structure is simplified, but installation becomes difficult due to limited hand room inside the module
Solution Approach 1:
The splice sleeve holder is divided into a stationary base portion attached to the module and a removable cover portion that can be taken off during installation. This segmentation allows the cover to be removed for easy access to splice sleeves during installation, then reattached to maintain the simplified stationary structure during operation.
Solution Approach 2:
The splice sleeve holder transitions from a completely stationary design to a dynamically configurable structure where the cover can be removed and reattached. This dynamic element provides hand room during installation while maintaining the simplified stationary appearance during normal operation.
2Ease of operation
If an open splice sleeve holder is used, then installation is easier, but splice sleeves can easily fall out causing fiber damage
Solution Approach 1:
The splice sleeve holder is segmented into a secure base portion that holds splice sleeves firmly and a separate cover portion that protects them. The base provides reliable retention while the removable cover allows easy installation access, resolving the contradiction between ease of installation and fiber protection.
Solution Approach 2:
The cover portion acts as a protective barrier that is put in place beforehand to prevent splice sleeves from falling out and causing fiber damage. It provides advance protection while allowing the base to maintain secure holding capability.
3Device complexity
If conventional cable management is used, then the module design is simple, but cable entry is limited to certain directions and angles
Solution Approach 1:
The cable management system incorporates three-dimensional cable trays and routing paths that allow cables to enter the module from multiple directions and angles. This dimensional approach maintains simple module design while providing versatile cable entry options.
4Device complexity
If traditional patch and splice modules are used, then the design is conventional, but they are not space-efficient and require multiple consumable items
Solution Approach 1:
The module integrates multiple functions including cable management, splice holding, and fiber organization into a single unified structure. This merging eliminates the need for separate consumable items like tie-wraps and multiple management components, improving installation efficiency while maintaining conventional design simplicity.
Solution Approach 2:
The module design incorporates multi-functional components that perform multiple tasks simultaneously, such as cable trays that also provide structural support and organize fibers. This universality reduces the number of consumable items needed and improves installation productivity.
