Movable Tray Equipment Panel for Optical Cable Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bladed chassis systems for optical adapters lack efficient cable management and access mechanisms, particularly in terms of tray mobility and splice region utilization.
Innovation Solution
The equipment panel features movable trays with termination and splice regions, including forward-facing ports for multi-fiber connectors and adjustable splice holders, allowing for enhanced cable management and access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If trays are made movable to enhance access to optical adapters, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The tray is designed to be movable relative to the chassis, transitioning between a retracted position for normal operation and an extended position for enhanced access to optical adapters. This dynamic configuration allows the same structure to serve multiple operational states, improving ease of operation without permanently increasing complexity.
Solution Approach 2:
The equipment panel is divided into modular components including the chassis, movable trays, and fixed cable management structures. This segmentation allows the tray to be independently moved while maintaining connection to the overall system, enabling enhanced access without requiring complete system reconfiguration.
2Adaptability or versatility
If splice regions are added to trays, then adaptability is improved, but device complexity increases
Solution Approach 1:
The tray is designed to perform multiple functions: housing optical adapters, providing cable management through integrated cable clamps and anchors, and incorporating splice regions for fiber optic splicing. This multi-functionality allows a single component to address diverse needs including connectivity, cable management, and repair operations.
Solution Approach 2:
The splice region and cable management structures are integrated within the tray structure, with cable clamps and anchors positioned to work in conjunction with the tray's movable and fixed features. This nested arrangement allows multiple functional elements to coexist within a compact footprint.
3Manufacturing precision
If multiple rows of ports are arranged in fixed orientation, then manufacturing precision is improved, but ease of operation deteriorates
Solution Approach 1:
The tray can be moved between retracted and extended positions, allowing the port arrangement to transition from a fixed, precision-manufactured configuration during assembly to a dynamically accessible configuration during operation. This enables both precise manufacturing and ease of operation in different operational contexts.

AI summary
An equipment panel includes one or more trays disposed within a chassis. Each tray has a two-layer termination region. Certain trays have a two-layer splice region. The splice region can be used to optically couple preterminated fibers within the tray to a trunk cable. Alternatively or in addition, the splice region can be used to fix broken fiber connections. A cable anchor and fanout arrangement mounts to the chassis as a unit.
