Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In optical communication systems, there is a need to transmit instruction signals to optical transceivers while maintaining the quality of the main data signal, particularly when multiple transceivers are involved and various channel settings are required, such as wavelength allocation, which can be time-consuming and prone to errors in manual settings.
Innovation Solution
The optical transceiver includes an optical transmission unit that superimposes an instruction signal onto a main communication data signal using amplitude shift-keying or phase shift-keying, allowing the instruction signal to be transmitted while controlling the amplitude based on a predetermined ratio to maintain signal quality, enabling autonomous channel setting and remote control of optical transceivers.

Engineering Contradiction Analysis
1Reliability
If an instruction signal is transmitted by modulating a high-frequency main signal and superimposing the instruction signal, then the instruction signal can be transmitted to the optical transceiver, but it is difficult to maintain the quality of the main signal while superimposing the instruction signal
Solution Approach 1:
The patent segments the transmission signal into two distinct components: a high-frequency main signal for data communication and a low-frequency instruction signal for control. By separating the frequency domains of these signals, the system can transmit both simultaneously without significant interference, maintaining the quality of the main signal while enabling instruction signal transmission.
Solution Approach 2:
The patent introduces frequency domain separation as an intermediary mechanism to resolve the conflict between main signal and instruction signal. By assigning different frequency ranges to different signal types, the system creates a harmonious coexistence environment where both signals can be transmitted without degrading each other's quality.
2Measurement precision
If manual setting of channel parameters such as wavelength is performed, then the optical transceiver can be configured, but the process is time-consuming and prone to errors
Solution Approach 1:
The patent enables the optical transceiver to perform self-configuration by automatically receiving and executing instruction signals that contain channel setting parameters such as wavelength assignments. This self-service capability eliminates the need for manual configuration, thereby reducing both the time required for channel setting and the potential for human errors.
Solution Approach 2:
The system transmits channel setting instructions in advance through the instruction signal mechanism, allowing the optical transceiver to be pre-configured with appropriate parameters before actual data communication begins. This preliminary action ensures accurate channel settings are established without requiring time-consuming manual intervention.

AI summary
A wavelength-tunable optical transmission unit outputs an optical signal in which a signal to be superimposed for giving an instruction to another optical transceiver is superimposed on a main signal. A wavelength-tunable optical reception unit receives an optical signal from another optical transceiver. A control unit controls the wavelength-tunable optical transmission unit and the wavelength-tunable optical reception unit. The wavelength-tunable optical transmission unit superimposes, on the main signal, the signal to be superimposed, by modulating the main signal into a signal having a waveform whose amplitude transitions between two levels by amplitude shift-keying or phase shift-keying, and controls an amplitude of the superimposed signal based on a value obtained by multiplying an amplitude of the main signal by a predetermined ratio.
