Fiber Optic Splitter Module Alignment With Accessible Chassis Adapters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fiber optic telecommunications systems face challenges in providing easy access for cleaning and ensuring correct alignment of modules within chassis, especially in cramped locations, while accommodating future expansion and reducing installation complexity.
Innovation Solution
A chassis design with integrally formed fiber optic adapters and a keying system for correct module orientation, combined with a flexible latch mechanism for secure mounting and horizontal float, allows easy access and alignment of modules within the chassis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If modules are mounted in a chassis with limited access sides or mounted in cramped locations, then installation space is optimized, but access for cleaning connectors becomes difficult
Solution Approach 1:
The chassis is divided into multiple accessible sides, with at least one side providing enhanced access to internal components. This segmentation allows the chassis to be installed in space-constrained locations while maintaining accessibility for maintenance operations on connectors and other components.
2Adaptability or versatility
If pre-configured transmission cables are installed to accommodate future expansion, then future growth capacity is provided, but access to connectors for cleaning is restricted
Solution Approach 1:
Transmission cables are pre-configured and pre-connectorized within the chassis to accommodate future module expansions. The connector access provision is designed in advance to allow maintenance personnel to reach connectors even when modules are installed in space-constrained configurations, enabling both future expansion and ongoing maintenance.
3Productivity
If modules are installed without proper alignment features, then installation speed is increased, but alignment precision with transmission cables deteriorates
Solution Approach 1:
Alignment features such as alignment pins, keyways, or asymmetric mounting structures are incorporated into the chassis and modules. These asymmetric elements guide modules into correct alignment with pre-configured transmission cables during installation, ensuring precise connector mating while maintaining straightforward installation procedures.

AI summary
A telecommunications assembly includes a chassis and a plurality of fiber optic splitter modules mounted within the chassis. Each splitter module includes at least one fiber optic connector. Within an interior of the chassis are positioned at least one fiber optic adapter. Inserting the splitter module through a front opening of the chassis at a mounting location positions the connector of the splitter module for insertion into and mating with the adapter of the chassis. The adapters mounted within the interior of the chassis are integrally formed as part of a removable adapter assembly. A method of mounting a fiber optic splitter module within a telecommunications chassis is also disclosed.
