Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the gain of the amplifier is adjusted during burst optical signal reception, then the signal amplitude becomes appropriate, but transmission efficiency decreases due to the need for redundant data during gain convergence
Solution Approach 1:
The patent applies preliminary action by pre-adjusting the gain of the amplifier before receiving the burst optical signal. The setting processor adjusts the gain in advance based on the wavelength of the local oscillation light, so that when the burst signal arrives, the gain is already converged to the appropriate value. This eliminates the need for redundant data that would otherwise be required during gain convergence, thereby maintaining high transmission efficiency while ensuring appropriate signal amplitude.
2Measurement precision
If the wavelength of the local oscillation light is switched to match different transmitting devices, then reception accuracy improves, but device complexity increases
Solution Approach 1:
The patent applies feedback by implementing a setting processor that receives wavelength information from the control device and automatically switches the wavelength of the local oscillation light accordingly. The system continuously monitors the wavelength requirements and adjusts the local oscillation light wavelength in real-time, ensuring accurate reception without manual intervention. This automated feedback mechanism improves reception accuracy while managing device complexity through intelligent control.
3Reliability
If redundant data is added to accommodate gain convergence time, then signal reception reliability improves, but transmission efficiency decreases
Solution Approach 1:
The patent eliminates the need for redundant data by performing preliminary gain adjustment before the burst optical signal arrives. The setting processor calculates and sets the appropriate gain value in advance based on the local oscillation light wavelength, ensuring that the amplifier is ready to process the signal immediately upon arrival. This preliminary action maintains signal reception reliability without sacrificing transmission efficiency, as no additional redundant data needs to be transmitted.
