What are the advantages of Coherent Optical Transmission System?
- High Chromatic Dispersion (CD) Robustness
- Can avoid Dispersion Compensation Units (DCUs)
- No need to have precise Fiber Characterization
- Simpler Network Design
- Latency improvement due to no DCUs
- High Polarization Mode Dispersion (PMD) Robustness
- High Bit Rate Wavelengths deployable on all Fiber types
- No need for “fancy”PMD Compensator devices
- No need to have precise Fiber Characterization
- Low Optical Signal-to-Noise Ratio (OSNR) Needed
- More capacity at greater distances w/o OEO Regeneration
- Possibility to launch lower per-channel Power
- Higher tolerance to Channels Interferences
