Focus on C and L Bands
In Dense Wavelength Division Multiplexing (DWDM), the primary focus is on the C-band and L-band.
Why?
- These bands provide the best performance, with minimal attenuation and dispersion.
- The spectrum includes:
- C-band
- Extended C-band
- Super C-band
- Similarly, L-band has extended and super variations.
Importance of Expanding Fiber Spectrum
Increasing the available spectrum in fiber-optic networks is crucial for:
- Internet Service Providers (ISPs) – To handle growing bandwidth demands.
- Data Center Interconnect (DCI) – For high-speed connectivity between data centers.
- Mobile Operators – Supporting 5G and beyond.
- Artificial Intelligence (AI) Applications – Enabling large-scale data transfer.
What is Spectrum Efficiency?
Spectrum efficiency refers to the optimal utilization of available spectrum to:
- Maximize data transmission rates
- Minimize interference
- Reduce spectrum wastage
Expanding Super C and Super L-band enhances capacity, making optical networks more efficient and scalable.
