Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If advanced optical access communication systems are deployed to meet increasing bandwidth demand, then service quality and coverage are improved, but deployment costs and complexity increase significantly
Solution Approach 1:
The patent combines multiple functions (optical modulation, phase control, intensity control, and backscattering compensation) into a single intelligent subscriber subsystem. This integration eliminates the need for separate middle equipment like routers and switches, thereby reducing deployment complexity while maintaining high bandwidth capacity.
Solution Approach 2:
The intelligent subscriber subsystem is designed to perform multiple functions simultaneously: it acts as an optical modulator, phase controller, intensity controller, and backscattering compensator. This multi-functionality reduces the number of required components and simplifies the overall network architecture, addressing the deployment complexity issue.
2Length of stationary object
If middle equipment like routers and switches are added to extend network reach, then coverage is improved, but deployment costs and device complexity increase
Solution Approach 1:
The patent extracts and eliminates the need for middle equipment (routers and switches) by implementing backscattering compensation directly at the subscriber subsystem. This allows optical signals to travel longer distances without requiring intermediate amplification or regeneration equipment, thereby extending network reach while reducing equipment quantity.
Solution Approach 2:
The patent introduces phase modulators and intensity modulators as intermediary components at the subscriber end to compensate for Rayleigh backscattering effects. These modulators act as mediators that enable long-distance signal transmission without requiring traditional middle equipment, thus extending network reach while maintaining low complexity.
3Length of stationary object
If Rayleigh backscattering compensation is implemented, then network reach is extended, but system complexity at subscriber subsystem increases
Solution Approach 1:
The patent merges phase control and intensity control functions into the intelligent subscriber subsystem, allowing backscattering compensation to be implemented without adding separate complex components. This integration extends network reach while keeping the subscriber subsystem complexity manageable through functional consolidation.
4Reliability
If traditional optical access networks are deployed, then infrastructure is established, but return on investment decreases due to high operational costs
Solution Approach 1:
The intelligent subscriber subsystem performs self-compensation for Rayleigh backscattering effects, eliminating the need for expensive operational maintenance and intermediate equipment. This self-service capability reduces operational costs while maintaining reliable network infrastructure, thereby improving return on investment.

Implementation Method 1
an optical signal from the object is received by the phase modulator, wherein the phase modulator modulates a phase of the optical signal
Implementation Method 2
the modulated optical signal is then modulated in intensity by the intensity modulator
Implementation Method 3
Together, these two critical optical modules can reduce the Rayleigh backscattering effect on the propagation of optical signals
