Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In transparent networks, improper light of unacceptable intensity or with wavelengths other than configured cannot be effectively detected or prevented from passing to subsequent stages.
Innovation Solution
A separation system comprising a separation unit that separates desired and improper signals by wavelength, and a detection unit that identifies the intensity of the improper signal, with a discarding unit to prevent the improper signal from mixing with the desired signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a transparent network is implemented without signal detection functions, then network simplicity and transparency are maintained, but improper signals cannot be detected or prevented from passing
Solution Approach 1:
The patent extracts the improper signal detection function from the main signal transmission path by introducing a separate detection unit that monitors a copy of the signal. This allows reliability improvement without significantly complicating the main network architecture, as the detection function is isolated in a dedicated unit that does not interfere with normal signal transmission.
Solution Approach 2:
The patent introduces an intermediary detection unit that acts as a mediator between the signal transmission and the control system. This intermediary unit receives signal copies, detects improper characteristics, and triggers control actions, thereby adding reliability without requiring direct integration of detection functions into the transmission path itself.
2Measurement precision
If wavelength separation is performed to detect improper signals, then signal identification capability is improved, but device complexity increases due to additional separation and detection units
Solution Approach 1:
The patent segments the signal processing function into distinct units: a separation unit that divides the optical signal into wavelength components, and a detection unit that analyzes specific wavelengths for improper characteristics. This segmentation enables precise wavelength detection while keeping each unit's complexity manageable and modular.
Solution Approach 2:
The patent applies local quality by focusing the detection unit on specific wavelength ranges that are most likely to contain improper signals. Rather than analyzing all wavelengths uniformly, the system concentrates detection resources on critical wavelength bands, improving measurement precision for the most important parameters while reducing overall system complexity.
