Solution Overview
Problem
The efficiency of detecting optical networks is low due to the need for manual testing devices to be carried to the site of optical splitters, which are prone to performance deterioration in high-temperature, high-humidity environments, leading to increased link loss and potential failures.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual testing devices are carried to the optical splitter site for detection, then detection accuracy is improved, but detection efficiency deteriorates
Solution Approach 1:
The patent uses optical signal copying principle where the testing optical signal is reflected back through the optical network to create a return signal that carries information about the network status. The management device analyzes this reflected signal to determine splitter and link status without physical presence at the splitter site, thereby improving detection efficiency while maintaining accuracy.
Solution Approach 2:
The patent introduces an optical reflective film as an intermediary element on the optical splitter. This reflective film enables the testing signal to be reflected back through the existing optical infrastructure, allowing remote detection through the management device without requiring manual intervention at the splitter location, thus resolving the contradiction between detection accuracy and efficiency.
2Productivity
If remote detection is implemented using reflective signals, then detection efficiency is improved, but measurement precision deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the testing optical signal is reflected back through the optical network and the return signal characteristics (power level, timing) are analyzed by the management device. This feedback loop provides information about splitter status and link integrity, enabling accurate remote detection by comparing the reflected signal properties against expected values.
Solution Approach 2:
The patent utilizes changes in optical signal parameters (power level, timing, reflection characteristics) to detect network status. By monitoring these parameter variations in the reflected signal, the management device can accurately determine splitter and link status remotely, maintaining measurement precision while improving detection efficiency.
