Optical Transceiver Channel Auto-Setting via Peer Signal Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manually setting channels for multiple optical transceivers in an optical transmission apparatus is time-consuming and prone to errors, especially when a large number of transceivers are involved.
Innovation Solution
The optical transceiver includes a wavelength variable transmitting and receiving unit, along with a control unit that autonomously sets channels by exchanging channel information through channel setting optical signals, allowing each transceiver to determine the channels for transmission and reception independently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual channel setting is performed for each optical transceiver, then channel allocation accuracy is improved, but setting time increases significantly
Solution Approach 1:
The optical transceiver autonomously performs channel setting by receiving channel information from another transceiver and automatically configuring its transmission and reception channels, eliminating the need for manual operator intervention and significantly reducing setting time while maintaining accurate channel allocation
Solution Approach 2:
The system establishes bidirectional communication between optical transceivers where channel information is exchanged and confirmed through feedback mechanisms, ensuring accurate channel allocation while automating the setting process to reduce time consumption
2Measurement precision
If manual channel setting is performed for multiple optical transceivers, then channel configuration accuracy is improved, but operational complexity increases
Solution Approach 1:
Each optical transceiver automatically configures its channels by receiving and processing channel information from peer transceivers, eliminating complex manual configuration steps and reducing operational complexity while maintaining configuration accuracy through automated validation
3Loss of time
If automatic channel setting is implemented, then setting time is reduced, but reliability may decrease due to potential automation errors
Solution Approach 1:
The automatic channel setting process incorporates bidirectional feedback where transceivers exchange channel information and confirm proper configuration, enabling automated speed while maintaining reliability through verification mechanisms that detect and correct potential errors
Solution Approach 2:
The system performs preliminary channel information exchange and validation before final channel configuration is completed, ensuring that automatic setting proceeds with pre-verified parameters to maintain reliability while achieving rapid deployment

AI summary
A wavelength variable optical transmitting unit is configured to be able to transmit a first channel setting optical signal including first channel information indicating a channel for the first channel setting optical signal. A wavelength variable optical receiving unit is configured to, when the optical transceiver receives a second channel setting optical signal from another optical transceiver, transfer second channel information contained in the second channel setting optical signal and indicating a channel for the second channel setting optical signal. A control unit is configured to control the wavelength variable optical transmitting unit and the wavelength variable optical receiving unit. The control unit sets, based on the second channel information that the wavelength variable optical receiving unit has transferred, a first channel indicated by the second channel information as a channel through which the wavelength variable optical receiving unit receives an optical signal.
