Fiber Management Tray and Cable Guide for High-Density Rack Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fiber management in fiber optic telecommunications and data centers faces challenges with increased fiber-count density, as existing devices require additional space beyond the rack-unit and lack efficient patch cord and cable management solutions.
Innovation Solution
A telecommunications panel with a body, fiber management tray, and cable management guide, featuring an adjustment arm assembly and latch mechanism for depth adjustment, allowing for efficient fiber and cable routing without requiring additional rack space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If fiber-count density is increased to 288 fibers per rack-unit, then fiber density is improved, but patch cord and cable management becomes more difficult
Solution Approach 1:
The patent divides the cable management system into multiple cable management guides (first guide, second guide, third guide) that are distributed across different rack units. Each guide handles specific cables, segmenting the management task across multiple locations rather than concentrating all management functions in one place, thereby improving ease of operation while maintaining high fiber density.
Solution Approach 2:
The patent utilizes vertical distribution across multiple rack units (1RU, 2RU, 3RU) to manage cables. Instead of managing all cables within a single horizontal plane, the system distributes cable management guides across different vertical levels and rack unit positions, adding a dimensional aspect to cable routing that simplifies management of high-density fiber connections.
2Quantity of substance
If fiber-count density is increased, then fiber density is improved, but additional area and volume beyond rack-unit becomes required
Solution Approach 1:
The patent makes existing rack-unit structures serve multiple functions. The rack units not only house fiber optic equipment but also contain integrated cable management guides and adjustment arm assemblies. This multi-functionality allows the system to manage 288 fibers per RU without requiring additional dedicated space for cable management, as the same rack units perform both fiber housing and cable routing functions.
Solution Approach 2:
The patent nests cable management guides within the existing rack-unit structure. The guides are positioned inside or attached to the rack units, and adjustment arm assemblies are nested within the panel body. This nesting approach allows cable management functionality to be contained within the existing rack-unit footprint, avoiding the need for additional external area.
3Ease of operation
If cable management guides are distributed across multiple rack units, then cable management is improved, but device complexity increases
Solution Approach 1:
The patent incorporates adjustable components including adjustment arm assemblies with latch mechanisms that allow dynamic repositioning of cable management guides. The guides can be moved between different rack unit positions and secured at various locations, providing flexibility in cable routing while maintaining a relatively simple base structure. This dynamic capability improves cable management without requiring a completely complex fixed structure.

AI summary
A telecommunications panel includes a body having a cassette opening, a fiber management tray, and a cable management guide. An adjustment arm assembly is attachable to the frame and includes a first sleeve having a first mount interface attachable to the frame and a second sleeve having a second mount interface attachable to the fiber management tray. The first sleeve includes a first sleeve opening configured to receive a latch assembly selectively permitting adjustment of the second sleeve along a depth direction to and from the first sleeve. The fiber management tray is attachable to the second mount interface. The tray includes a platform having a platform opening. The cable management guide includes a guide frame having a plurality of sidewalls with a selectively openable passage providing access to a cable routing area. An insert member extends from the guide frame and is selectively positioned into the platform opening.
