Telecommunications Module Frame With Multi-Direction Cable Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber optic telecommunications systems face challenges in managing cable access and expansion, particularly in cramped locations, while ensuring cleanliness and protection against thermal expansion and insect infestation, with limited access to components for maintenance and future growth capabilities.
Innovation Solution
A telecommunications module with a dual-layered cable management structure and removable cover, incorporating a fiber optic component like a splitter or multiplexer/demultiplexer, provides cable protection through crimp assemblies and bend radius management, along with insect prevention devices, housed within a chassis/frame that allows modular expansion and easy access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If modules are mounted in a fixture with limited access or in cramped locations, then space utilization is improved, but access to components for maintenance and cleaning becomes difficult
Solution Approach 1:
The fixture is divided into multiple access points: front access for module installation/removal, rear access for connector cleaning, and side access for cable management. This segmentation allows maintenance operations to be performed from different directions without requiring complete disassembly, resolving the contradiction between compact space utilization and ease of component access.
2Adaptability or versatility
If transmission cables are pre-configured with maximum capacity, then future expansion capability is improved, but access to connectors for cleaning during installation becomes limited
Solution Approach 1:
A removable connector cleaning tool or access device is introduced as an intermediary mechanism. This device allows technicians to access and clean pre-configured connectors on transmission cables without disrupting the maximum capacity configuration or future expansion capabilities, thus resolving the contradiction between adaptability and ease of operation.
3Reliability
If cable management features are integrated within module housing, then cable protection is improved, but device complexity increases
Solution Approach 1:
Cable management features such as cable clips, bend radius guides, and strain relief structures are merged directly into the module housing structure. This integration provides comprehensive cable protection while avoiding the addition of separate complex subsystems, thus resolving the contradiction between reliability and device complexity by combining multiple functions into a unified structure.

AI summary
A telecommunications chassis comprises a cable sealing portion defining at least one cable opening configured to sealably receive a cable and a module mounting portion extending from the cable sealing portion, which further comprises a housing defining an open front closable by a door to define an interior, a rear wall, a right wall, and a left wall. A plurality of module mounting locations is provided in a vertically stacked arrangement, each configured to receive a telecommunications module through the open front. An exterior of the housing includes a first column of radius limiters defining curved profiles for guiding cables from the front toward the rear with bend control. A second column of radius limiters in the form of spools is spaced apart and generally parallel to the first column of radius limiters and a third column of radius limiters, at least some of which are in the form of spools, is also spaced apart and generally parallel to the first and second columns of radius limiters. The rear wall defines an opening for accessing from the exterior of the housing rear ends of modules to be mounted in the housing for signal input, wherein the exterior also includes a plate at least partially overlapping the opening for protection of cables entering the opening.
