Pre-terminated Optical Fiber Tray Mount for Data Center Interconnects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The labor-intensive and time-consuming process of fusion splicing optical fibers in data center installations, which can result in varying quality and signal attenuation due to technician skill and experience, and the need for a simpler method to manage high fiber-count cable interconnections within data centers.
Innovation Solution
The use of pre-terminated trunk cable assemblies with furcation bodies and adapter trays that allow for easy connection and management of optical fiber ribbons, featuring ferrules and tray mounts that facilitate secure and efficient interconnections without additional tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fusion splicing is used to connect optical fibers, then optical connectivity is achieved, but installation time and labor cost increase significantly
Solution Approach 1:
The optical fibers are pre-terminated with connectors at the factory before cable assembly. This preliminary action allows the connectors to be precisely aligned and secured in controlled manufacturing conditions, eliminating the need for time-consuming field splicing operations while ensuring consistent connection quality.
Solution Approach 2:
Connectors serve as intermediary components that facilitate quick connection between optical fibers. Instead of directly splicing fibers in the field, pre-attached connectors act as mediators that enable rapid plug-and-play interconnection while maintaining reliable optical transmission.
2Reliability
If fusion splicing is performed by field technicians, then optical fiber connections are made, but connection quality varies due to technician skill differences
Solution Approach 1:
Optical fiber termination is performed in advance under controlled factory conditions where skilled technicians can ensure consistent, high-quality connections. This transfers the complex splicing operation from variable field conditions to standardized manufacturing environments, eliminating quality variation due to different technician skills.
Solution Approach 2:
The pre-terminated cable assembly provides self-contained, factory-calibrated connections that do not require field technician intervention for splicing. The system serves itself by delivering ready-to-connect components with consistent quality built into the manufacturing process.
3Reliability
If traditional cable management methods are used, then optical fibers are organized, but signal degradation occurs due to improper routing and bending
Solution Approach 1:
Optical fibers are pre-routed and pre-positioned within the cable assembly during manufacturing. This preliminary organization ensures proper bend radii and routing paths are established before installation, preventing signal degradation from improper field installation while reducing the complexity of post-installation cable management.
Solution Approach 2:
The cable assembly incorporates localized features such as strain relief sections, bend radius controls, and organized fiber pathways at critical points. These local quality enhancements protect signal transmission at vulnerable locations without requiring complex overall cable management systems.

AI summary
A system for managing connections for optical fibers that extend from a cable comprises a tray and a tray mount. The tray includes a body having at least one tray mount receiver. The tray mount comprises a base that defines an interface for cooperating with the at least one tray mount receiver, and comprises a clamshell tube configured to receive the optical fibers. The clamshell tube is movable between an open position and a closed position. The tray mount is configured couple the optical fibers to the tray without additional tools.
