Pre-connectorized Optical Termination Assembly for FTTH
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of existing optical termination boxes in FTTH networks is cumbersome and time-consuming for end users, requiring multiple steps and handling of delicate optical fibers and connectors, which increases the risk of damage and inconvenience.
Innovation Solution
An optical termination assembly with a pre-connectorized drop cable and an optical termination box that can be mounted without opening the compartment, featuring external fixing elements for secure attachment to a support structure, minimizing the need for in-apartment handling of optical fibers and connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the optical termination box is installed using conventional methods requiring opening the compartment and handling optical fibers and connectors, then the installation can be completed, but the installation time is long and the risk of damage to optical components is high
Solution Approach 1:
The optical fibers are pre-connectorized to optical connectors within the optical termination box before delivery to the end user. The compartment is pre-assembled with all necessary components (optical fibers, connectors, splices) arranged and secured. This preliminary preparation eliminates the need for operators to handle delicate optical components during installation, reducing both installation time and the risk of damage.
2Reliability
If the optical termination box is sealed to protect optical components, then the protection of optical fibers and connectors is improved, but the ease of installation and maintenance is reduced
Solution Approach 1:
The optical termination box is designed with a removable compartment or access mechanism that allows operators to access the optical components for initial installation and configuration, after which the compartment can be sealed to protect the components. This extraction approach provides protection during normal operation while maintaining ease of installation and maintenance when needed.
3Strength
If multiple fixing operations are performed within the apartment, then the optical termination box can be securely installed, but the installation complexity and time increase
Solution Approach 1:
The optical termination box is designed with integrated mounting features that combine multiple functions (securing the box to the wall, organizing cables, and protecting components) into a single unified structure. The box can be mounted as one complete unit rather than requiring separate operations for mounting and component installation, reducing installation complexity while maintaining secure installation.
