Fiber Optic Cable Anchoring System With Modular Sealant
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fiber optic cable anchoring systems in enclosures are not easily accessible and user-friendly, making it difficult to transfer loading from fiber optic cables to the enclosure, which can lead to unprotected optical fibers during installation and maintenance.
Innovation Solution
A cable sealing and anchoring system with a primary sealant assembly, secondary cable tube, and secondary cable sealant assembly, along with a cable anchoring assembly, allows for easy installation and anchoring of fiber optic cables by routing them through sealed ports and using actuators to pressurize sealants for environmental protection and secure anchoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional cable anchoring systems are used in fiber optic enclosures, then the structural strength and reliability are maintained, but the ease of operation and accessibility for installation and maintenance deteriorates
Solution Approach 1:
The anchoring system is divided into separate modular components: a cable access assembly with sealant for environmental protection, and a separate anchoring assembly with clamping mechanism. This segmentation allows independent optimization of each function and simplifies installation procedures.
Solution Approach 2:
A secondary cable tube acts as an intermediary component between the primary sealant assembly and the anchoring assembly. This intermediary structure provides a dedicated pathway for the cable, separating the sealing function from the anchoring function and improving overall accessibility.
2Adaptability or versatility
If cable anchoring is performed after cable routing, then the cable installation flexibility is improved, but the protection of optical fibers from loading deteriorates
Solution Approach 1:
The sealant is applied to the cable in advance, before the anchoring operation. This preliminary sealing action ensures that the optical fibers are protected from environmental loading and contamination before they are exposed during the anchoring process.
Solution Approach 2:
The anchoring assembly is nested within the cable access assembly structure, with the secondary cable tube positioned within the primary sealant assembly. This nested configuration allows the anchoring operation to be performed while maintaining the protective seal.

AI summary
A cable sealing and cable anchoring system has a primary sealant assembly that includes a primary volume of sealant that defines primary through-ports. The primary sealant assembly includes a primary actuator for pressurizing the primary volume of sealant. The system also has a secondary cable tube that mounts within one of the primary cable through-ports and a secondary cable sealant assembly that mounts within a first end of the secondary cable tube. The secondary cable sealant assembly includes a secondary sealant volume that defines secondary cable through-ports. The secondary cable sealant assembly also includes a secondary actuator for pressurizing the secondary sealant volume. The system further has a cable anchoring assembly for anchoring a strength member of a secondary cable to the secondary cable tube. The cable anchoring assembly is supported by the secondary cable tube adjacent the second end of the secondary cable tube.
