Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical transceivers in high-speed data transmission networks often require external hardware and systems for optimization, which can be inefficient and slow, as they are typically only coupled by an optical link without the capability for self-optimization.
Innovation Solution
The method involves one optical transceiver generating electrical optimization data, converting it into an optical signal, and transmitting it over the optical link to another transceiver, which recovers the data to adjust its transmission characteristics, allowing for self-optimization without external host systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If optical transceivers are coupled only by an optical link without external hardware, then device complexity is reduced, but optimization capability deteriorates
Solution Approach 1:
The patent enables optical transceivers to perform self-optimization by generating and exchanging optimization data through electrical and optical signals. Each transceiver autonomously adjusts its transmission characteristics based on recovered optimization data from its peer, eliminating the need for external host systems or additional hardware while maintaining optimization capability.
Solution Approach 2:
The optical link serves dual functions: transmitting both data signals and optimization data. The transceivers utilize existing electrical signal generation and optical signal conversion capabilities for optimization purposes, making the system multi-functional without requiring dedicated optimization hardware.
2Productivity
If external host systems are used for optimization, then optimization capability is maintained, but speed and efficiency deteriorate
Solution Approach 1:
The optimization process is transferred from external host systems to the optical transceivers themselves. Each transceiver autonomously generates optimization data, converts it to optical signals, transmits it over the optical link, recovers the data, and adjusts its transmission characteristics, enabling faster and more efficient optimization without external intervention.
Solution Approach 2:
The patent implements a feedback mechanism where transceivers exchange optimization data through the optical link, allowing each transceiver to continuously monitor and adjust its transmission characteristics based on real-time conditions, thereby improving optimization speed and efficiency.

AI summary
Two or more optical transceivers coupled to each other by an optical link to optimize communication over the optical link. A first transceiver generates electrical data that represents an operational parameter for optimization. The transceiver then converts the electrical data into an optical signal and transmits the optical signal over the optical link to a second transceiver. The second transceiver recovers the electrical data from the optical signal and uses the recovered electrical data to change characteristics of the optical signal transmitted by the second transceiver.
