Solution Overview

Problem

Existing data communication systems are inadequate for handling high-bandwidth applications, such as social networks processing large amounts of multimedia data, as they require inefficient processes to determine the Forward Error Correction (FEC) mode for data streams.

Innovation Solution

Embedding FEC mode information in a designated field of alignment markers allows transceivers to quickly identify and establish the correct FEC mode, enabling efficient data processing and backward compatibility with existing systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If traditional methods are used to determine FEC mode, then system compatibility is maintained, but the time and processing effort required to identify FEC mode increases significantly

Engineering Contradiction:

Improvetime to determine FEC modeVSAvoidFEC mode identification process

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The patent embeds FEC mode information directly into the alignment marker before data transmission begins. This preliminary inclusion of FEC mode identification data in the alignment marker allows the receiving transceiver to quickly identify the FEC mode without requiring complex detection processes, thereby reducing the time and processing effort needed to determine FEC mode while maintaining system compatibility.

Inventive Principle:

Principle #10Preliminary action

2Speed

If FEC mode information is embedded in alignment markers, then FEC mode identification speed improves, but the complexity of the transmitting transceiver increases

Engineering Contradiction:

ImproveFEC mode identification speedVSAvoidtransmitting transceiver structure

Core Design Contradiction:

SpeedVSDevice complexity

Solution Approach 1:

The patent reuses the existing alignment marker structure, which is already present in the data communication system, to carry FEC mode information. By making the alignment marker multi-functional (serving both alignment and FEC mode indication purposes), the patent avoids adding separate dedicated structures, thus minimizing the increase in transmitting transceiver complexity while achieving fast FEC mode identification.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If alignment markers are used for FEC mode indication, then backward compatibility with existing systems is maintained, but the amount of data that must be processed increases

Engineering Contradiction:

Improvesystem compatibilityVSAvoiddata processing volume

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent embeds FEC mode information only in the specific portion of the alignment marker that is relevant for FEC mode identification, rather than processing the entire alignment marker data. This localized approach allows the system to maintain compatibility with existing alignment marker structures while minimizing the amount of data that must be processed for FEC mode determination.

Inventive Principle:
