Fiber Optic Cable Flexible Conduit Termination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber optic cables, particularly trunk cables, have low flexibility, making it difficult to maneuver them around tight bends and within small spaces, which poses a challenge during installation and connection to telecommunications equipment.
Innovation Solution
The development of a fiber optic cable with a flexible conduit portion that includes a terminating device, allowing the optical fibers to pass through and providing increased flexibility at the end connecting to telecommunications equipment, while maintaining protection of the internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional stiff cable structure is used, then the cable has high strength and stability, but the cable has low flexibility and is difficult to maneuver around tight bends and within small spaces
Solution Approach 1:
The cable is divided into distinct segments: a flexible conduit portion with a different material composition than the traditional cable body. This segmented approach allows the conduit portion to provide flexibility while the main cable body maintains its structural strength and stability.
Solution Approach 2:
The flexible conduit portion uses a different material composition compared to the main cable body, creating local quality differences. The conduit portion has enhanced flexibility properties while the main cable maintains traditional strength characteristics, allowing each part to optimize its function.
2Ease of operation
If the cable structure is modified to increase flexibility, then the cable becomes easier to install and connect, but the protection of internal components may be compromised
Solution Approach 1:
The flexible conduit portion is nested within the existing cable structure, with the conduit containing the optical fibers and surrounded by the traditional cable jacket and strengthening members. This nested configuration provides flexibility while maintaining protection of internal components through the existing protective layers.
Solution Approach 2:
The flexible conduit portion uses a composite material composition that combines flexibility with protective properties. The conduit is formed from materials that provide both ease of manipulation and protection for the internal optical fibers, eliminating the need to sacrifice protection for flexibility.
