Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current optical communication systems face challenges in efficiently encoding and transmitting large amounts of data over long distances without physical alterations to the communication path, as the demand for bandwidth increases with the number of devices.
Innovation Solution
The use of power-based encoding schemes that map binary characters to varying transmission power outputs, allowing repeated instances of a binary character to be represented by a single instance at a higher power level, thereby optimizing data transmission without requiring physical changes to the optical communication path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional optical encoding schemes are used, then the optical communication path can transmit data, but the bandwidth capacity is limited and cannot meet increasing demand without physical alterations
Solution Approach 1:
The patent changes the power parameter of optical signals to encode multiple binary characters. Instead of using only presence/absence of light pulses, the system varies the power level of pulses to represent different numbers of repeated binary characters, thereby increasing data transmission capacity without adding physical infrastructure
Solution Approach 2:
The patent merges multiple binary characters into a single optical pulse by encoding them together based on their repetition pattern. Multiple binary characters that are the same are combined into one pulse with a power level indicating how many characters were merged, reducing the total number of pulses needed for transmission
2Quantity of substance
If more binary characters are transmitted using traditional methods, then data volume increases, but the number of transmission pulses increases proportionally
Solution Approach 1:
Multiple identical binary characters are merged into a single optical pulse. The power level of the pulse encodes the count of merged characters, so transmitting N identical characters requires only one pulse instead of N separate pulses, directly increasing transmission rate while maintaining data volume
3Loss of time
If repeated binary characters are encoded individually, then each character requires a separate pulse, but using power-based encoding allows multiple characters to be represented by a single pulse at higher power level
Solution Approach 1:
Repeated binary characters are merged into a single pulse with power level proportional to the number of characters. This reduces transmission time by sending one pulse instead of multiple pulses, while the power consumption increases proportionally to encode the count of merged characters
Solution Approach 2:
The system changes from binary presence/absence encoding to multi-level power encoding. By varying the power parameter of optical pulses, the system can represent multiple binary characters in a single pulse, trading increased power usage for reduced transmission time

AI summary
A system for transmitting data over an optical communication path is configured to receive data to be encoded in a bitstream for transmission using an optical communication path and encodes the received data to obtain a bitstream. The system is further configured to determine that the bitstream includes a sequence of consecutive bits, and obtain a power level at which to transmit a portion of the bitstream based on a count of the consecutive bits in the sequence. The system may be configured to selectively activate a light source at a power level according to a modulation scheme to optically transmit the portion of the bitstream at the power level.
