Solution Overview
Problem
Current optical communication systems face challenges in efficiently encoding and transmitting data over increased bandwidth demands without physical alterations to the communication path, as existing methods do not effectively leverage transmission power output to optimize data encoding.
Innovation Solution
The proposed solution involves using power-based compression algorithms to map binary characters to varying transmission power levels, where repeated instances of a binary character are transmitted at higher power outputs, allowing for efficient partitioning of data into transmission packets that maintain throughput without physical changes to the optical communication path.

Engineering Contradiction Analysis
1Productivity
If traditional optical encoding schemes are used, then the optical communication path can transmit data, but the bandwidth demand cannot be met without physical alterations to the communication path
Solution Approach 1:
The patent changes the encoding parameters by using variable transmission power levels to represent multiple binary characters. Instead of using fixed power levels for single bits, the system transmits repeated binary characters by varying the power output (e.g., higher power for repeated instances), thereby increasing data capacity without physical modifications to the optical path.
Solution Approach 2:
The patent introduces a new dimension for encoding by utilizing transmission power as an additional encoding parameter beyond traditional intensity modulation. By mapping binary characters to power levels and using power variation to represent repetition counts, the system effectively adds a dimensional layer to the encoding scheme, enabling higher bandwidth utilization.
2Productivity
If transmission power is increased to encode repeated binary characters, then more data can be transmitted efficiently, but energy consumption increases
Solution Approach 1:
The patent applies partial action by selectively increasing power only for packets containing repeated binary characters, rather than transmitting all data at maximum power. The system determines the optimal number of packets and uses power variation only where needed to encode repetition information, thereby improving transmission rate while controlling energy consumption.
Solution Approach 2:
The patent performs preliminary encoding of the bitstream to identify repeated binary characters and determine optimal packet partitioning before transmission. This preliminary analysis allows the system to plan power allocation efficiently, transmitting at higher power only when necessary to convey repetition information, thus optimizing the trade-off between transmission rate and energy consumption.
3Productivity
If power-based encoding is implemented, then bandwidth utilization improves, but the complexity of encoding and decoding algorithms increases
Solution Approach 1:
The patent segments the encoded bitstream into multiple transmission packets, where each packet represents a specific number of binary characters. This segmentation simplifies the encoding process by breaking down complex repeated sequences into manageable units that can be independently encoded and transmitted, reducing the overall complexity of the encoding algorithm while improving bandwidth utilization.

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.
