Reversible Duplex Fiber Connector Latch for Polarity Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing duplex optical fiber cable connectors are often unidirectional, making it cumbersome and time-consuming for installers to correct cross-over errors between transmitting and receiving cables, and are difficult to remove from high-density panels due to limited space and complex locking mechanisms.
Innovation Solution
A reversible optical fiber connector design with a snap-fit housing and a latch system that allows for interchangeable polarity and easy removal, featuring a handle and boot for stress relief and simplified installation and removal processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If duplex optical fiber cable connectors are designed as unidirectional connectors, then connection reliability is improved, but ease of operation deteriorates when polarity correction is needed
Solution Approach 1:
The connector design incorporates a dynamic polarity reversal mechanism where the connector body can be rotated 180 degrees relative to the housing to switch between normal and reversed polarity configurations. This dynamic adjustment allows the connector to adapt its orientation based on installation requirements while maintaining secure engagement through the latch mechanism.
2Reliability
If duplex optical fiber cable connectors use complex locking mechanisms, then connection reliability is improved, but ease of operation deteriorates in high-density panel environments
Solution Approach 1:
The locking mechanism is segmented into a latch component and a separate locking lever component. The latch provides secure engagement when inserted, while the locking lever offers a simplified manual release mechanism that can be actuated with minimal space, enabling easy removal even in high-density panel environments where maneuverability is constrained.
3Reliability
If installer needs to correct polarity errors in unidirectional connectors, then connection reliability is maintained, but loss of time increases due to cumbersome reinstallation
Solution Approach 1:
The connector enables dynamic polarity reversal by rotating the connector body 180 degrees relative to the housing while maintaining engagement through the latch mechanism. This allows installers to correct polarity errors in-situ without removing the connector from the panel, significantly reducing correction time while maintaining connection reliability.
4Area of stationary object
If duplex optical fiber cable connectors are designed for high-density panels, then space utilization is improved, but ease of operation deteriorates due to limited manipulation space
Solution Approach 1:
The locking mechanism is divided into a latch for secure engagement and a separate locking lever for manual release. The locking lever is designed to be actuated with minimal movement, allowing operators to remove connectors even in the constrained spaces of high-density panels where full manipulation of traditional locking mechanisms would be difficult.

AI summary
A connector for optically connecting an optical fiber to an optical fiber port, the connector defining a first length, L1, as measured between a leading edge and a trailing edge of the connector when the connector is in a locked configuration, and a second length, L2, as measured between the leading edge and the trailing edge of the connector when the connector is in an unlocked configuration, wherein L1 is different than L2. In an embodiment, L2 is greater than L1. In another embodiment, the connector comprises a boot and a housing, and the boot and housing are configured to float relative to one another.
