Summary

Review of the drivers of the transformation of fiber optic networks and the transport of higher bandwidth over single wavelengths – 800G and 1.6T, to support this.

• The increasing demand for bandwidth 
• The rising need for stronger network security
• The need to build more agile and flexible networks. 

To address these challenges, three key technological advancements are set to shape the industry in 2025:

• L-band spectrum for Expanded fiber utilization
  The introduction of the L-band spectrum, alongside 800G coherent modules, significantly enhances fiber utilization by doubling the bandwidth of existing infrastructure. This innovation presents challenges such as the need for adjustments in amplification, ROADMs, management, and power budgets. Advanced solutions are developed to enable scalable, cost-effective upgrades to meet growing capacity demands.
• Flex grid technology for greater network adaptability
  Flex grid technology enables dynamic allocation of spectrum, accommodating different wavelength bandwidths and improving spectral efficiency, ensuring operators can maximize fiber utilization while future-proofing their networks for emerging technologies. This adaptability is critical for supporting high-capacity channels like 800G and 1.6T, and addressing the needs of data center interconnects and long-haul networks.
• Quantum Key Distribution (QKD) for enhanced security
  Network security is becoming more important on one hand, and more challenging on the other, as cyber threats become more sophisticated and the capabilities of quantum computing advance. QKD leverages quantum channels to transport secured encryption keys, providing a solution to these evolving security threats. Partnering with leading QKD providers to integrate this technology into DWDM networks, ensures the robust protection between DCIs, especially in sensitive applications.
