Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing live fiber identifier tools are inadequate for detecting the presence and direction of light signals in dual fiber cables, as they can incorrectly indicate signal traffic when two signals travel in opposite directions within the same cable.
Innovation Solution
An optical fiber identifier tool with a housing and a head portion containing a slot for dual fiber cables, equipped with a clamp, photo detectors, and processing components that adjust a threshold factor to differentiate between light signal directions, allowing accurate indication of signal traffic in both directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing live fiber identifier tools are used on dual fiber cables, then the tool structure remains simple, but the measurement precision deteriorates due to inability to correctly distinguish signal directions in both fibers
Solution Approach 1:
The tool divides the detection function into separate photo detectors for each fiber, with each detector dedicated to detecting light leakage from its corresponding fiber. This segmentation allows independent processing of signals from each fiber, enabling accurate bidirectional detection without interference between fibers.
Solution Approach 2:
Each photo detector is positioned to detect light leakage from a specific fiber at a specific location within the cable. The local positioning of detectors ensures that each detects only the intended fiber's leakage, providing localized and unambiguous detection results for each fiber's signal direction.
2Productivity
If the tool detects light leakage from both fibers simultaneously, then the productivity increases, but the reliability decreases due to potential false indications from opposite direction signals
Solution Approach 1:
By segmenting the detection into separate channels for each fiber, the tool can simultaneously monitor both fibers without interference. Each fiber's leakage is detected independently, allowing parallel processing and maintaining high productivity while preventing false indications through isolated detection channels.
Solution Approach 2:
The processing components act as intermediaries that receive signals from both photo detectors and compare the leakage amounts. This intermediary processing layer filters out false indications by analyzing the relative leakage levels from both fibers before generating the final detection result.
3Adaptability or versatility
If the tool uses fixed threshold detection, then the ease of operation is maintained, but the adaptability deteriorates when dealing with different cable configurations and signal conditions
Solution Approach 1:
The threshold factor is made dynamically adjustable rather than fixed, allowing the tool to adapt to different cable configurations, fiber types, and signal conditions. The processing components can modify the threshold based on detected leakage levels and cable characteristics, maintaining ease of operation through automated adjustment.
Solution Approach 2:
The tool incorporates feedback mechanisms where the processing components continuously monitor the detection results and adjust the threshold factor accordingly. This feedback loop enables the tool to automatically adapt to varying operating conditions while maintaining simple user operation, as the adjustment occurs automatically based on real-time detection data.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tool reliably indicates the presence and direction of light signals in dual fiber cables by adjusting the threshold factor based on the sensitivity difference between photo detectors, reducing false indications and ensuring accurate detection of signal traffic in modern data centers.
Implementation Method 1
Two photo detectors are mounted at determined locations inside the head portion 3... A small fraction of any light signal traveling in the cable fiber will leak from the fiber and exit from the cable bend, and the photo detectors are located so that depending on the direction of the light signal in the fiber, one of the detectors receives more of the light that exits the cable than the other detector.
Data Source
AI summary
A live fiber identifier tool includes a head portion having a slot. A cable containing a pair of optical fibers can be inserted in the slot and forced to bend inside the head portion when a trigger is operated. Any light signal in a given fiber partially leaks from the fiber and exits the cable bend. Two photo detectors are located so that one of the detectors receives more light from the cable bend than the other detector depending on the signal direction in the given fiber. Processing components coupled to the detectors and the indicator define a threshold factor that corresponds to a determined difference between the outputs of the detectors. If the difference between the detector outputs does not exceed the threshold factor, an indicator on the tool reports that light signals are traveling in the pair of optical fibers in opposite directions along the cable.
