Hollow Core Fiber Splicing Chamber for Contaminant Evacuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hollow core fibers (HCFs) are vulnerable to contaminants during deployment, which can impede data propagation and degrade performance, making detection and isolation difficult due to their hollow nature and susceptibility to dust, dirt, and other particulates.
Innovation Solution
A contaminant-mitigation technique involving a chamber that seats the ends of two HCFs, followed by cutting and joining the exposed ends using pressurization or vacuum to remove contaminants, and then fusing the ends using fusion splicing techniques to minimize scattering or reflection of light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If HCF ends are sealed during shipping and handling, then contaminants are prevented from entering the fiber core, but the ends cannot be prepared for splicing
Solution Approach 1:
The HCF ends are pre-sealed during manufacturing to protect against contaminants during shipping and handling. The seal is designed to be removable or breakable, allowing the ends to be exposed and prepared for splicing when needed. This preliminary protective action resolves the contradiction by providing contamination protection during transport while enabling easy preparation for splicing at the deployment site.
Solution Approach 2:
The HCF is segmented into a sealed protective portion and an exposed splicing portion. The seal acts as a temporary barrier that can be selectively removed, dividing the fiber into protected and accessible sections. This segmentation allows the fiber to maintain contamination protection during handling while enabling splicing operations when required.
2Ease of operation
If HCF ends are cut to expose strands for splicing, then splicing can be performed, but contaminants can enter and lodge in the fiber core
Solution Approach 1:
A controlled environment or protective housing serves as an intermediary between the exposed HCF ends and the external environment. This intermediary structure allows splicing operations to be performed while preventing contaminants from entering the fiber core during the exposure period. The housing may include features such as protective covers, controlled atmosphere, or cleanroom integration.
Solution Approach 2:
Pressurized gas flows or vacuum systems are used to create a protective environment during splicing. Gas flows can blow contaminants away from the fiber ends, while vacuum systems can actively remove contaminants that approach the exposed cores. These pneumatic and hydraulic mechanisms resolve the contradiction by enabling splicing operations while actively preventing contaminant intrusion.
3Object-affected harmful factors
If a clean work area policy is enforced, then contaminant introduction is reduced, but there is no guarantee of a contaminant-free environment
Solution Approach 1:
A dedicated splicing housing or controlled environment structure serves as an intermediary that provides physical isolation between the HCF ends and the general work area. This housing creates a localized clean zone that does not require complete control of the entire work area, reducing the complexity of clean room requirements while still protecting against contaminant introduction during critical splicing operations.
Solution Approach 2:
Active pneumatic systems such as gas flows or vacuum pumps provide dynamic protection against contaminants during splicing. These systems create localized protective environments that are more effective and potentially simpler than maintaining a completely contaminant-free work area, as they actively manage contamination at the point of need rather than requiring comprehensive environmental control.
