In our latest study, we dive deep into the effects of Stimulated Raman Scattering (SRS) on multi-band optical transport. Looking we analyze the GSNR and its OSNR and SNR_NL components for a 70 km scenario, revealing key insights:
🔹 Without SRS (dot-dashed curves), the OSNR is consistently 3 dB lower than the SNR_NL at each band center frequency.
🔹 With SRS (dotted curves), we see OSNR depletion in the O-to-S bands, shifting them towards an almost linear regime. Conversely, the L- and U-bands enter a nonlinear regime due to OSNR enhancements from SRS.
🔹 The C-band acts as a transition between these regimes, balancing OSNR and SNR_NL effects.
Key Takeaways for Multi-Band Optical Transport:
✅ Accurate GSNR computation must include SRS effects on both OSNR and SNR_NL.
✅ Multi-band optical controllers are essential to optimize amplifier settings across bands.
✅ Expanding traffic to additional bands requires careful power and amplification management.
As we push the boundaries of optical transport, understanding these dynamics is critical for next-gen high-capacity networks. Looking forward to more discussions on this!
