Solution Overview

Problem

Existing fiber splice protectors face challenges in routing fiber splice connections along curved paths without degrading the optical and mechanical performance of the fiber splice connection.

Innovation Solution

A fiber splice protector is designed with an inner protection portion, a strength portion, and an outer protection portion. The strength portion, which can include an elongated flexible portion, a contoured surface, or a helical spring, is configured to limit bending of the fiber splice portion to a minimum bend radius, allowing the protector to be routed along a curved path without compromising performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional fiber splice protectors are used, then the fiber splice connection is protected, but the protector cannot be routed along sharp curved paths without degrading optical and mechanical performance

Engineering Contradiction:

Improverouting flexibilityVSAvoidoptical and mechanical performance

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The fiber splice protector is divided into multiple segments including a first portion, second portion, and third portion arranged in series. This segmentation allows each portion to independently accommodate bending stresses, enabling the protector to be routed along curved paths while maintaining the integrity of the fiber splice connection within the protective housing.

Inventive Principle:

Principle #1Segmentation

2Strength

If the fiber splice connection is protected with a rigid structure, then mechanical strength is improved, but the protector cannot follow curved routing paths

Engineering Contradiction:

Improvemechanical strengthVSAvoidinstallation flexibility

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The protective housing exhibits varying structural properties along its length, with certain regions designed to be more flexible to accommodate bending, while other regions maintain rigidity to protect the fiber splice connection. This local differentiation of structural quality enables the housing to provide mechanical strength where needed while allowing curvature where required for installation.

Inventive Principle:

Principle #3Local quality

3Adaptability or versatility

If the fiber splice connection is allowed to bend freely, then routing flexibility is improved, but the optical and mechanical performance degrades

Engineering Contradiction:

Improverouting flexibilityVSAvoidoptical performance

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The protective housing is pre-configured with structural features that counteract bending forces before they can affect the fiber splice connection. By designing the housing with appropriate stiffness and geometric characteristics, the invention prevents excessive bending of the fiber splice connection while still allowing the overall protector to follow curved routing paths.

Inventive Principle:

Principle #9Preliminary anti-action

AI summary

A fiber splice protector may include a splice protection portion having a through bore extending along a length thereof and being structurally configured to receive a splice connection of a first fiber with a second fiber therein and a strength portion configured to extend along at least a portion of the length of the splice protection portion. The strength portion is structurally configured to limit bending of the splice connection to a minimize bend radius so as to permit the strength portion to be routed along a curved path without degrading optical and mechanical performance of the splice connection.
