Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manually setting channels for multiple optical transceivers on an optical transmission apparatus is time-consuming and prone to errors, necessitating a more efficient and autonomous channel setting method.
Innovation Solution
The optical transceiver includes a wavelength-tunable optical transmission and reception unit, along with a control unit that autonomously sets channels by transmitting and receiving channel setting optical signals, allowing the transceiver to determine and establish communication channels without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual channel setting is performed for multiple optical transceivers, then channel configuration can be completed with basic equipment, but the time required for setting increases significantly and labor intensity increases
Solution Approach 1:
The optical transceiver autonomously performs channel setting by transmitting channel setting optical signals and automatically determining its own transmission and reception channels without requiring manual configuration. The control unit automatically processes the channel information from received signals and configures the wavelength-tunable optical reception unit accordingly
Solution Approach 2:
The optical transceiver transmits channel setting optical signals containing channel information before actual data communication begins. This preliminary channel establishment allows the system to prepare transmission and reception channels in advance, enabling faster subsequent communication setup
2Ease of manufacture
If manual channel setting is performed for multiple optical transceivers, then channel configuration can be done with simple equipment, but the complexity of the setting process increases and error probability increases
Solution Approach 1:
The optical transceiver autonomously determines its reception channel by processing channel information from received channel setting optical signals. The control unit automatically extracts channel identifiers and configures the wavelength-tunable optical reception unit, eliminating manual configuration errors and improving setting accuracy
Solution Approach 2:
The system uses bidirectional channel setting optical signals where each optical transceiver transmits its channel information and receives the other's channel information. This feedback mechanism allows automatic verification and matching of transmission and reception channels, ensuring accurate pairing without manual intervention
3Adaptability or versatility
If additional optical transceivers are installed, then system capacity increases, but manual channel investigation and setting is required which reduces productivity
Solution Approach 1:
When additional optical transceivers are installed, each unit automatically performs channel setting by transmitting and receiving channel setting optical signals with existing transceivers. The control unit autonomously determines appropriate transmission and reception channels without requiring manual channel investigation, enabling rapid system expansion
Solution Approach 2:
The channel setting mechanism is universally applicable to any optical transceiver in the system. The same automatic channel setting protocol works for initial installation and for adding new transceivers later, providing a unified approach that simplifies system expansion regardless of the number of units

AI summary
A wavelength-tunable optical transmission unit repeatedly transmits a first channel setting optical signal while changing a transmission channel until a wavelength-tunable optical reception unit receives a second channel setting optical signal in response to a first instruction signal. When the wavelength-tunable optical reception unit receives the second channel setting optical signal, a channel indicated by second channel information is set as a channel of an optical signal to be received by the wavelength-tunable optical reception unit. When a second instruction signal is received after the first instruction signal is received, a channel of an optical signal to be transmitted by the wavelength-tunable optical transmission unit is set to a first designated channel, and a channel of an optical signal to be received by the wavelength-tunable optical reception unit is set to a second designated channel.
