Innovation Solution
A switch system incorporating a digital signal processor and a lookup table, along with a microprocessor in a linear drive pluggable optics apparatus, where the microprocessor transmits identification codes to the digital signal processor to retrieve optoelectronic parameters from the lookup table, allowing the microprocessor to control the optics apparatus and adjust parameters based on diagnostic monitoring data to ensure compatibility and efficiency.

1Reliability
If each optical module includes a digital signal processor, then the optical module can work independently, but the power consumption of the switch system becomes very high
Solution Approach 1:
Multiple optical modules share a single digital signal processor located in the switch apparatus. Instead of each optical module having its own DSP, the DSP is centralized and serves multiple optical modules through electrical connections, reducing the total number of DSPs from 32 (one per module) to 1 (shared), thereby significantly reducing power consumption while maintaining operational capability
Solution Approach 2:
The centralized digital signal processor in the switch apparatus serves multiple optical modules simultaneously, making it a universal resource. The DSP can process signals from different optical modules by receiving identification codes and retrieving corresponding optoelectronic parameters from a lookup table, enabling one processor to perform the functions previously requiring multiple processors
2Use of energy by moving object
If a centralized digital signal processor is used to reduce power consumption, then power efficiency improves, but the system requires a lookup table and parameter matching mechanism
Solution Approach 1:
Optoelectronic parameters for different optical modules are pre-calculated and stored in a lookup table in the switch apparatus before runtime. When an optical module connects, the system performs a quick lookup based on the module's identification code rather than calculating parameters in real-time, simplifying the runtime operation and making the added complexity manageable through pre-computation
Solution Approach 2:
A lookup table acts as an intermediary between the centralized digital signal processor and the optical modules. The lookup table stores pre-configured optoelectronic parameters and enables the DSP to quickly retrieve appropriate parameters based on identification codes, simplifying the parameter management process and reducing the computational burden on the DSP
