Communications Service Providers Explore 800G Coherent Optics for Network Evolution

What's Happening?

Communications service providers (CSPs) are increasingly focusing on the adoption of 800G coherent pluggable optics as part of their IP over DWDM strategies. A recent survey conducted by Heavy Reading, now part of Omdia, involved 80 CSPs globally and highlighted their diverse applications for 800G optics. While hyperscalers are pushing for the highest data rates, CSPs are planning to start deployments at 400G data rates, with 53% of respondents indicating this approach. The survey also revealed that 45% of CSPs expect to use a mix of rates up to 800G as capacity demands increase. The flexibility of 800G coherent pluggables allows CSPs to optimize current network demands while preparing for future growth, particularly in AI-driven traffic.

Why It's Important?

The adoption of 800G coherent optics is significant for CSPs as it offers a flexible and scalable solution to meet increasing data demands. This technology enables CSPs to enhance their network capacity and efficiency, which is crucial in the face of growing data traffic and the need for high-speed connectivity. The ability to strategically deploy these optics across various rates provides CSPs with a future-proof foundation, allowing them to adapt to evolving technological and market demands. This development is particularly relevant as industries increasingly rely on AI and other data-intensive applications, necessitating robust and adaptable network infrastructures.

What's Next?

As CSPs continue to integrate 800G coherent optics into their networks, they will need to address management preferences and operational practices. The survey indicates a divergence in management strategies, with some CSPs favoring optical controllers for managing coherent pluggables. This approach, while offering autonomy and direct control, may impact interoperability and increase costs. CSPs will need to balance these considerations as they evolve their network infrastructures. The ongoing evolution of IP over DWDM strategies will likely see further developments in management practices and technology adoption, shaping the future of telecommunications networks.
