Engineering Contradiction Analysis
1Quantity of substance
If a single OLT serves multiple ONTs through a passive optical splitter, then fiber bandwidth is shared among multiple endpoints reducing the amount of fiber necessary, but computational complexity increases due to varying timing distributions and data traffic patterns from diverse subscriber services
Solution Approach 1:
The patent segments the MAC layer processing into separate modular transceivers, with each transceiver dedicated to a specific access technology (PON, DOCSIS, Ethernet). This segmentation allows each transceiver to handle timing distributions and data traffic patterns specific to its access technology independently, reducing overall computational complexity while maintaining the shared fiber infrastructure benefits.
Solution Approach 2:
The patent implements dynamically reconfigurable transceivers that can adapt their MAC layer processing parameters based on the specific timing distributions and data traffic patterns of different subscriber services. This dynamic adaptation enables efficient handling of diverse services without increasing fixed computational complexity.
2Ease of operation
If MAC layer processing is centralized in the OLT, then data handling for multiple access technologies is simplified, but efficiency decreases due to lack of tailored processing for different access technologies with varying timing distributions
Solution Approach 1:
The patent applies local quality by implementing MAC layer processing with technology-specific optimizations in each modular transceiver. Each transceiver is tailored to handle the specific timing distributions and data traffic patterns of its assigned access technology (PON, DOCSIS, or Ethernet), achieving both simplicity through modular design and efficiency through specialized processing.
Solution Approach 2:
The patent creates a universal modular transceiver platform that can be configured to handle multiple access technologies. Each transceiver module maintains simplicity through standardized interfaces while achieving efficiency through technology-specific MAC layer processing capabilities, allowing the system to scale across different access technologies without complexity increases.
3Adaptability or versatility
If diverse subscriber services are accommodated with varying timing distributions, then service diversity increases, but computational overhead increases due to lack of tailored processing
Solution Approach 1:
The patent segments computational processing by dedicating specific modular transceivers to specific access technologies and service types. This segmentation allows the system to accommodate diverse subscriber services with varying timing distributions while maintaining manageable computational overhead, as each segment processes only its designated service type with optimized algorithms.
Solution Approach 2:
The patent utilizes parameter changes by allowing each modular transceiver to dynamically adjust its processing parameters based on the specific timing distributions and traffic patterns of the services it handles. This enables the system to accommodate service diversity efficiently by adapting processing parameters rather than increasing overall computational complexity.
