Fiber Optic Harnesses With Pre-Connectorized Cables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fiber optic terminals with permanently attached feeder cable stubs lack flexibility and increase manufacturing complexity due to customized lengths for varying applications, limiting the ability to supply feeder cable stubs separately from the terminal.
Innovation Solution
The use of pre-connectorized fiber optic cables with a fiber optic harness and support member that allows for separate attachment or integration with the terminal, featuring hardened or indoor connectors for outdoor and indoor use, enabling feeder cable stubs to be supplied separately and connected without splicing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If feeder cable stubs are permanently attached to fiber optic terminals during assembly, then optical connectivity is established, but flexibility is reduced and manufacturing complexity increases due to customized lengths for different applications
Solution Approach 1:
The fiber optic assembly is divided into separate components: a fiber optic terminal and a fiber optic harness with pre-connectorized cables. The harness can be detached and replaced independently, allowing different cable lengths and configurations to be supplied separately without changing the terminal structure. This segmentation enables flexibility while maintaining reliable optical connectivity through the connector interface.
2Reliability
If feeder cable stubs are permanently attached to fiber optic terminals, then optical connections are established, but manufacturing complexity increases due to varying configurations for different applications and customers
Solution Approach 1:
The fiber optic terminal is designed with a universal interface that accepts standard fiber optic harnesses with pre-connectorized cables. The terminal enclosure includes openings that accommodate various cable configurations through a common support member structure. This universal design allows the same terminal to work with different cable lengths and types, reducing manufacturing complexity while maintaining reliable optical connections.
3Adaptability or versatility
If feeder cable stubs are supplied separately from fiber optic terminals, then flexibility is improved, but connection reliability may be compromised without proper support structures
Solution Approach 1:
A support member is introduced as an intermediary component between the fiber optic terminal and the pre-connectorized cable. The support member includes openings that securely hold the cable connectors in place, ensuring proper alignment and stable optical connections. This intermediary structure maintains connection reliability while allowing the cable to be supplied separately and easily replaced.
