Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If breakout cable assemblies use fixed cable lengths and connector types, then manufacturing and installation are simplified, but flexibility in supporting different fiber cable lengths, materials, and media interfaces is limited
Solution Approach 1:
The breakout cable assembly is segmented into modular components: a main connector (QSFP/MPO) that accepts multiple individual cables, each with separate connectors (LC/SC). This segmentation allows each cable to have different lengths, materials, and connector types while maintaining a unified interface at the main connector, thereby achieving versatility without excessive complexity.
Solution Approach 2:
The main connector is designed as a universal interface that can accommodate multiple different cable types and connector configurations simultaneously. The QSFP/MPO connector serves multiple functions by providing a common attachment point for various fiber optic cables with different specifications, enabling one component to perform multiple roles.
2Ease of manufacture
If breakout cable assemblies use standardized connectors and cable configurations, then ease of manufacture is improved, but adaptability to different communication services and interfaces is reduced
Solution Approach 1:
The cable assembly system is made dynamic and reconfigurable. Individual cables can be added, removed, or replaced independently at the connector level without affecting the entire assembly. This dynamic configuration allows the same manufactured base unit to adapt to different communication services and interfaces as needed, balancing standardization with versatility.
3Ease of operation
If multiple individual cables are bundled in a single jacket, then cable management and organization are improved, but heat dissipation and power management become more difficult
Solution Approach 1:
While cables are bundled together in a single jacket for management purposes, the segmentation principle is applied at the connector level where each cable maintains its independence. This allows for organized cable routing and management while preserving the ability to individually manage heat and power for each cable connection through separate connector interfaces.
