Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the existing ROF communication system uses independent design modules for feedback link and uplink, then the system can effectively solve distortion during signal amplification, but the system requires extensive redesign and resource allocation when switching between different standards, frequency bands, and transmission power levels
Solution Approach 1:
The patent implements a universal remote machine design where the feedback link and uplink share common design modules including the same optical module, electrical module, and antenna. This multi-functional architecture allows the system to handle both feedback and uplink operations using identical hardware components, enabling seamless switching between different communication standards, frequency bands, and transmission power levels without requiring redesign of the entire module.
2Reliability
If the system redesigns the entire module when replacing different standards and frequency bands, then the signal amplification can be optimized for each specific application, but the process consumes a lot of manpower, material resources and development costs
Solution Approach 1:
The patent creates a universal remote machine with standardized modules that can be configured for different applications through parameter settings rather than physical redesign. The feedback link and uplink both use the same optical module, electrical module, and antenna design, eliminating the need for costly redesign when adapting to different standards or frequency bands.
Solution Approach 2:
The patent divides the remote machine into independent functional segments including optical modules, electrical modules, and antenna elements. These segmented modules can be independently configured and combined to meet different application requirements without redesigning the entire system, reducing development costs and manufacturing complexity.
3Power
If the system redesigns the entire module for different transmission power levels, then the power amplification can be precisely controlled, but the process takes a lot of time and resources
Solution Approach 1:
The patent implements a universal power amplification module that can operate at multiple transmission power levels without requiring physical redesign. The same electrical module and antenna are used across different power levels, with power control achieved through electronic configuration rather than hardware changes, significantly reducing the time and resources required for adaptation.

AI summary
An ROF communication remote machine and an ROF system are disclosed. The machine comprises a first packaging module and a second packaging module. The first packaging module comprises a first branch and a second branch. The first branch is used for converting a downlink optical signal, and sending the downlink electrical signal to the second packaging module. The second branch receives the downlink electrical signal, converts the downlink electrical signal into a downlink optical signal, sends the downlink optical signal to the local machine, receives an uplink electrical signal, and sends the uplink electrical signal to the local machine. The second packaging module is used for amplifying the power of the downlink electrical signal, filtering the downlink electrical signal, then feeding back the downlink electrical signal to another component, receiving the uplink electrical signal, and sending the uplink electrical signal to the second port.
