Fiber Management Tray Routing Ribbonized Fibers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional optical fiber splice trays face issues with routing and attenuation due to the preferential bend of ribbonized fibers, and they often fail to accommodate both traditional and non-traditional fiber types, as well as non-ribbonized fibers, leading to inefficiencies in splicing and space management in data centers and other environments.
Innovation Solution
The design of a fiber management tray and wall cabinet system that includes a tray body with partitioned sections for storage and splicing, wing structures for guiding fibers, and a backboard with cable manifolds and a splice section, allowing for improved routing and organization of both ribbonized and non-ribbonized optical fibers, and enabling efficient splicing and space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional optical fiber ribbons are used in known splice trays with figure 8 routing, then splicing of multiple fibers can be achieved, but twisting and attenuation occur due to the preferential bend of the ribbons
Solution Approach 1:
The tray interior is divided into multiple storage portions (first rear storage portion, second rear storage portion, and side storage portions) with distinct routing paths. Each portion provides a dedicated route for fiber ribbons, eliminating the need for figure-8 coiling and reducing twisting and attenuation.
2Adaptability or versatility
If splice trays are designed to accommodate up to 12 mass splices, then multiple fiber splicing can be achieved, but the trays cannot accommodate both traditional and non-traditional fiber types simultaneously
Solution Approach 1:
The splice tray is designed with multiple types of storage portions and routing paths that can accommodate different fiber types (traditional ribbons, intermittently bonded ribbons, and non-ribbonized fibers) within a single tray, making it a universal solution for various fiber configurations.
3Productivity
If multiple splice trays are provided at the same location in a cabinet, then splicing capacity increases, but space consumption increases significantly in data centers
Solution Approach 1:
Multiple fiber types and splicing functions are merged into a single integrated splice tray design. The tray combines multiple storage portions, routing paths, and splice holders that can handle both ribbonized and non-ribbonized fibers, effectively replacing the need for multiple separate trays and reducing cabinet space requirements.

AI summary
Wall cabinets and fiber management trays are provided. A cabinet includes a mounting panel, the mounting panel including a rear panel and a mounting bracket extending from the rear panel along a transverse axis. The cabinet further includes a backboard mountable to the mounting panel such that a gap is defined between the backboard and the rear panel along the transverse axis. The backboard includes a main body defining a first cable manifold and a second cable manifold each extending along a longitudinal axis and a splice section positioned between the first cable manifold and the second cable manifold along a lateral axis. The cabinet further includes a plurality of splice trays disposed in the splice section.
