• Future-proofed for DWDM (Dense Wavelength-Division Multiplexing) upgrades.

8. Software Ecosystem

• Operating System:

• Runs Cisco IOS XR, optimized for carrier-grade reliability.

• Regular updates (e.g., Release 7.0 introduces IPv6-over-OTN support).

• Lifecycle Support:

• End-of-Sale (EOS): Announced for 2025 (check Cisco lifecycle tracker for specifics).

• Extended Support: Available via Cisco SMARTnet contracts.

9. Strategic Use Cases

• Metro Core Networks: High-capacity aggregation for 5G backhaul.

• Data Center Interconnect (DCI): Low-latency, encrypted links between campuses.

• Hybrid Cloud Networking: Integration with Cisco ACI and multi-cloud architectures.
