Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate transceivers are used for data and management signals, then management function is achieved, but system resources are occupied, bandwidth is reduced, and cost increases
Solution Approach 1:
The patent merges data signals and management signals into a single transceiver system. The driver circuit simultaneously processes both data signals and management signals, and the optical transmitter combines them into a single optical signal for transmission over one fiber. This eliminates the need for separate transceivers and reduces system complexity while maintaining management functionality.
Solution Approach 2:
The transceiver is designed with multi-functionality to handle both data transmission and management signal transmission through the same hardware components. The driver circuit and optical transmitter serve dual purposes, enabling the system to achieve multiple functions (data communication and network management) without requiring additional dedicated resources.
2Reliability
If separate transceivers are used for data and management signals, then management function is achieved, but bandwidth is reduced
Solution Approach 1:
By combining data signals and management signals into a single optical transmission path, the system eliminates the bandwidth consumption associated with separate transceivers. The merged signal transmission allows full utilization of the available optical fiber bandwidth for both data and management purposes simultaneously.
3Reliability
If separate transceivers are used for data and management signals, then management function is achieved, but cost increases
Solution Approach 1:
The patent reduces system cost by merging data and management signal transmission into a single transceiver unit. This eliminates the need to purchase, install, and maintain separate transceiver hardware, thereby reducing overall system cost while preserving essential management capabilities.
4Reliability
If management signals are transmitted separately, then management function is achieved, but data signal transmission is affected
Solution Approach 1:
The system merges management signals with data signals in the optical transmission domain, allowing both to share the same fiber infrastructure. The driver circuit and optical transmitter handle both signal types simultaneously, ensuring that management signal transmission does not interfere with or reduce data signal transmission capacity.
