Optical Fiber Loop Relaxation via Intermediary Management Recess
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical fiber loops in telecommunications management apparatuses are difficult to relax due to tight wrapping around radius limiter blocks, leading to potential signal losses as fibers shrink and become tightly wound, making it challenging to manage and organize fibers effectively.
Innovation Solution
A telecommunications management apparatus with a base plate, radius limiter blocks, fiber loop passages, and fiber loop management recesses that include guide grooves to facilitate the use of a fiber loop management device for relaxing fibers by spacing them away from the radius limiter blocks, ensuring minimal bend radius and orderly loop configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If optical fibers are wound in looped configurations around radius limiter blocks, then fibers are stored in an organized manner, but fibers become tightly wound and difficult to relax
Solution Approach 1:
A fiber loop management device is introduced as an intermediary component between the radius limiter block and the optical fiber. This device includes a management recess that receives and holds the fiber, allowing it to be positioned and secured at a controlled distance from the radius limiter block, thereby preventing tight winding while maintaining organized storage
Solution Approach 2:
The fiber management system is divided into separate functional components: the radius limiter block that defines the minimum bend radius, the fiber loop management device that holds and positions the fiber, and the base plate that provides structural support. This segmentation allows each component to perform its specific function independently, enabling effective fiber relaxation
2Area of stationary object
If fibers are tightly wound in loops, then compact storage is achieved, but signal losses occur due to tight winding
Solution Approach 1:
The fiber loop management device acts as a mediator that maintains an optimal distance between the fiber and the radius limiter block. The management recess provides a controlled environment that prevents the fiber from being tightly wound against the radius limiter, thereby eliminating signal losses while still achieving compact storage through organized loop configuration
Solution Approach 2:
The system controls the spatial parameter of fiber positioning by using the management recess to hold the fiber at a specific distance from the radius limiter block. This parameter control ensures that the fiber maintains proper loop geometry that prevents signal degradation while achieving space-efficient storage
3Reliability
If radius limiter blocks are used to ensure minimum bend radius, then fiber protection is improved, but fiber loop relaxation becomes difficult
Solution Approach 1:
The fiber loop management device serves as an intermediary that bridges the protective function of the radius limiter block and the operational need for easy fiber manipulation. By providing a management recess that can receive and hold the fiber, it allows technicians to easily access, position, and relax fiber loops without compromising the minimum bend radius protection
Solution Approach 2:
The system provides dynamic fiber management capability through the management recess, which allows the fiber to be easily inserted, positioned, and adjusted. This dynamic access point enables simple relaxation operations while the radius limiter block continues to provide static protective constraints on the minimum bend radius
