Summary
Symmetrical dispersion compensation in optical communication systems reduces pulse distortions caused by Kerr nonlinearity. This method is effective for 10-Gbit/s return-to-zero pulse transmission over standard monomode fiber with large amplifier spacing.
Area of Science:
- Optical communications
- Nonlinear optics
- Fiber optics
Background:
- Cascaded communication systems face challenges with pulse distortion due to Kerr nonlinearity.
- Standard monomode fiber with large amplifier spacing requires effective dispersion compensation.
Purpose of the Study:
- To investigate optical 10-Gbit/s return-to-zero pulse transmission.
- To examine the impact of dispersion compensation on pulse distortions in cascaded systems.
- To determine the optimal arrangement of compensation sections.
Main Methods:
- Simulating 10-Gbit/s return-to-zero pulse transmission.
- Employing dispersion compensation using standard monomode fiber sections.
- Analyzing the effects of symmetrical ordering of precompensation and postcompensation sections.
Main Results:
- Pulse distortions from Kerr nonlinearity are significantly diminished.
- Symmetrical ordering of compensation sections proved effective.
- The total number of precompensation and postcompensation sections being equal is key.
- Repositioning of compensation sections is not critical for performance.
Conclusions:
- Symmetrical dispersion compensation is a viable strategy for mitigating Kerr nonlinearity effects.
- This approach enhances the performance of 10-Gbit/s optical systems.
- The findings offer practical insights for designing robust fiber optic communication networks.
