Summary
This study introduces a modified hybrid subcarrier/amplitude/phase/polarization (H-SAPP) modulation to exceed 400 Gb/s optical transmission. The enhanced scheme boosts bandwidth efficiency for higher aggregate data rates.
Area of Science:
- Optical communications
- Digital signal processing
- Modulation techniques
Background:
- Increasing demand for higher data rates in optical networks necessitates advanced modulation schemes.
- Existing modulation techniques face limitations in achieving ultra-high single-channel transmission speeds.
Purpose of the Study:
- To present a modified coded hybrid subcarrier/amplitude/phase/polarization (H-SAPP) modulation scheme.
- To demonstrate its capability for achieving beyond 400 Gb/s single-channel optical transmission.
Main Methods:
- Utilizing available resources and geometric properties to enhance bandwidth efficiency.
- Implementing a modified H-SAPP scheme capable of 11 bits/symbol encoding.
Main Results:
- Achieved a single-channel transmission rate of 440 Gb/s.
- Demonstrated the effectiveness of the modified H-SAPP scheme at 50 Giga Symbol/s (GS/s).
Conclusions:
- The modified H-SAPP modulation scheme offers a viable path towards ultra-high-speed optical transmission.
- This technique significantly increases system aggregate rates by improving bandwidth efficiency.
