Modular Fiber Frame for High-Density Optical Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunication networks face challenges in upgrading to high-speed fiber optic connections due to the cost and complexity of installing new infrastructure, particularly in densely populated areas where obtaining new rights of way is difficult, and existing copper cabinets have limited space for optical fiber integration, risking damage to fibers and increased attenuation.
Innovation Solution
A modular fiber frame system that retrofits existing copper cabinets with a high-density connection module, preterminated cable harnesses, and a splitter bracket to manage optical splitter modules on the front side, reducing the need for backside access and minimizing fiber bending, while allowing easy expansion of fiber network capacity within the same footprint as legacy copper networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If fiber cables and pre-terminated harnesses are added into an existing copper cabinet, then fiber network capacity is expanded, but the risk of damage to fiber optic pigtails and fan outs increases due to limited space and potential tight bends
Solution Approach 1:
The fiber frame is divided into distinct functional sections: a cable access area at the back for cable entry and termination, a connection module mounted on the back side for secure fiber termination, and a front side with splitter brackets and cable management features. This segmentation isolates the vulnerable fiber optic pigtails and fan outs in a protected backside area with adequate space, preventing tight bends and damage while allowing high-density fiber capacity on the front side.
2Area of stationary object
If fiber network components are loaded into an existing copper cabinet with limited depth (less than or equal to 6 inches), then space utilization is improved, but the ease of installation and fiber routing becomes more difficult
Solution Approach 1:
The connection module is mounted vertically on the back side of the fiber frame, utilizing the depth dimension of the cabinet effectively. This vertical mounting arrangement, combined with the backside placement of connection ports, allows fiber cables to be routed from the front through the frame body to the backside connections, simplifying installation by providing clear access paths within the limited 6-inch depth constraint.
3Quantity of substance
If a high density connection module is used to increase connection capacity, then fiber connection density is improved, but the device complexity increases
Solution Approach 1:
The fiber frame serves multiple functions: it provides structural support for high-density connection modules, acts as a cable management system with integrated splitter brackets, provides protection for fiber optic components through its enclosed design, and facilitates easy installation with pre-configured cable access and routing paths. This multi-functionality consolidates what would otherwise require multiple separate components into a single integrated unit, maintaining simplicity despite high connection density.

AI summary
A modular fiber frame is disclosed that comprises a generally rectangular frame body, a high density connection module attached to a front side of the frame body, a splitter bracket to hold a plurality of optical splitter modules on the front side of the frame body. All of the splitter connections can be made on the front side of the modular fiber frame, and a preterminated cable harness optically connected to connection ports on a back of the connection module, wherein the connection module includes a protective cover over said connection ports. In some embodiments, the exemplary modular fiber frame can utilize a second preterminated cable harness optically connected to a back of the connection module.
