Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors and adaptors for two-fiber mechanical transfer type ferrules are not optimized for high-density network panels, leading to fiber management issues, maintenance challenges, and accessibility problems due to their dimensions and design, which obstruct access to release mechanisms and cause unnecessary service interruptions.
Innovation Solution
Development of micro-MT connectors and adaptors with optimized dimensions and a remote release mechanism, including a latch body, latch spring, ferrule, and pull-tab, designed for simplex, duplex, and quad configurations, to enhance accessibility and reduce fiber management issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional 2-fiber connectors are used in high-density network panels, then fiber connection functionality is achieved, but accessibility to release mechanisms is obstructed and service interruptions occur
Solution Approach 1:
The connector is divided into separate functional components: a latch body that remains engaged with the adaptor and a pull-tab that can be remotely actuated. This segmentation allows the release mechanism to be accessed without manipulating the entire connector assembly, resolving the accessibility obstruction problem in high-density panels.
Solution Approach 2:
A pull-tab is introduced as an intermediary element between the operator and the latch release mechanism. The pull-tab transmits force remotely to actuate the latch spring and release the connector, eliminating the need for direct access to the latch body and solving the accessibility issue.
2Productivity
If 12-fiber MPO fan-out jumpers are used to connect multiple Tx-Rx ports, then all fibers are activated simultaneously, but service interruptions propagate to all ports when one connector malfunctions
Solution Approach 1:
The fan-out jumper system is segmented into independent 2-fiber connector units, each with its own latch body and pull-tab. This allows individual ports to be serviced or disconnected without affecting other ports, maintaining service continuity while preserving multi-port productivity.
Solution Approach 2:
Each connector position in the fan-out jumper is given independent control through its own latch mechanism and pull-tab. This local quality enables selective activation or deactivation of individual fiber pairs, ensuring that a malfunction at one position does not propagate to other positions.
3Area of stationary object
If connector dimensions are optimized for high-density panels, then space is reduced, but accessibility and maintenance become more difficult
Solution Approach 1:
The pull-tab serves as a long-reach intermediary that extends the operator's ability to access the latch release mechanism. Even when the latch body is positioned deep within the adaptor in a compact configuration, the pull-tab can be actuated from a distance, maintaining ease of maintenance while preserving space optimization.
Solution Approach 2:
By separating the latch body from the actuation interface (pull-tab), the design allows the latch body to be compactly positioned within the adaptor while the pull-tab extends outward for easy access. This segmentation resolves the conflict between compact dimensions and maintenance accessibility.
4Adaptability or versatility
If unused 2-fiber connectors are kept active in fan-out jumpers, then cable management complexity increases, but future service capability is preserved
Solution Approach 1:
Each 2-fiber connector in the fan-out jumper is segmented with its own independent latch mechanism and pull-tab. This allows individual connectors to be easily disconnected and reconnected without affecting other connectors, simplifying cable management while preserving the ability to activate or deactivate individual ports as needed for future service capability.
