Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional optical fiber connectors face challenges with sensitivity to dust and contaminants, and require significant physical forces for insertion, which degrades performance and is problematic in space-constrained environments.
Innovation Solution
A module housing with an array of Very Small Form Factor (VSFF) connectors and a trunk cable system that includes a fanout module to break out optical fibers into ribbon fibers, enabling high-density, scalable, and secure optical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional optical fiber connectors are used, then connectivity is provided, but sensitivity to dust and contaminants degrades performance
Solution Approach 1:
The connector employs a nested structure where the fiber optic cable is inserted through a receptacle, and a cap is placed over the receptacle to enclose and protect the fiber connection. This nested configuration creates a protective barrier that shields the sensitive optical interface from dust and contaminants while maintaining connectivity functionality.
2Reliability
If traditional connectors are used, then optical connections are established, but significant physical forces are required for insertion
Solution Approach 1:
The connector replaces traditional mechanical insertion mechanisms with a push-on style connection system. The fiber optic cable is inserted through a receptacle and secured using a simple pushing motion rather than requiring significant insertion forces, thereby reducing the mechanical effort needed while maintaining stable optical connections.
3Productivity
If high fiber density is implemented, then bandwidth and transmission capacity are increased, but space constraints are exacerbated
Solution Approach 1:
The connector system is divided into modular components including a module housing, individual VSFF connectors, and a fan out module. This segmentation allows for flexible configuration and high fiber density to be achieved through multiple small connector units rather than requiring a single large connector, thereby increasing capacity while managing space constraints.
Solution Approach 2:
The patent transitions from traditional planar connector arrangements to a three-dimensional configuration using VSFF connectors that extend from the front of a module housing. This dimensional change enables higher port density and fiber capacity within the same physical footprint by utilizing vertical and depth dimensions rather than only horizontal space.
4Area of stationary object
If VSFF connectors are used, then space footprint is reduced, but connector complexity increases
Solution Approach 1:
The VSFF connector design incorporates multi-functional elements where the receptacle serves both as the fiber insertion point and as a structural support for the cap mechanism. The fan out module integrates multiple functions including fiber distribution, routing, and connection to multiple VSFF connectors. This universality reduces overall system complexity despite the compact size of individual connectors.

AI summary
An apparatus comprises a module. The module comprising a module housing and an array of Very Small Form Factor (VSFF) connectors extending from a front of the module housing. Each of the VSFF connectors comprises a connector housing having a port at a front end of the connector housing, and a set of optical connections positioned within the port. A trunk cable, comprising a set of optical fibers, extends from the rear of the module housing. Within the module housing, the trunk cable is attached to a fan out module, where the set of optical fibers are broken out into a set of ribbon fibers that are attached to the VSFF connectors.
