• Advanced FEC (Forward Error Correction) for 80km+ fiber spans.

• Network Resilience:

• 1+1 APS (Automatic Protection Switching) with sub-50ms failover.

• Mesh networking with dynamic path computation (GMPLS).

• Security:

• AES-256 encryption for data in transit.

• Secure boot and role-based CLI access.

4. Design & Aesthetic Engineering

• Form Factor:

• 13-RU shelf-compatible line card with hot-swappable optics.

• Compact dimensions: 436 mm (W) x 483 mm (D) x 89 mm (H).

• LED Indicators:

• Real-time status LEDs for optical power, FEC errors, and alarms.

• Thermal Management:

• Redundant, variable-speed fans with N+1 redundancy.

5. User Experience Enhancements

• Management Interfaces:

• Cisco Transport Manager GUI for topology visualization and configuration.

• RESTCONF/YANG APIs for automation (Ansible/Cisco NSO integration).

• Troubleshooting Tools:

• Built-in OTDR (Optical Time-Domain Reflectometer) for fiber diagnostics.

• Packet capture and analysis via SPAN/TAP mirroring.

• Training:

• Cisco Validated Designs (CVDs) for common metro network architectures.

6. Pricing Structure

• Line Card Cost:

• 35k–45k USD (varies by region and licensing).

• Hardware Costs:

• ONS 15454 shelf (empty): ~12k–18k USD.

• Transponder modules (CFP2-DCO): 8k–12k each.

• Support:

• Annual SMARTnet contracts: 10k–15k/year for 24/7 escalation.

7. Battery-Free Operation

• Power Requirements:

• External DC power (-48V DC) or AC-to-DC converters.

• No internal batteries; relies on facility UPS systems.

8. Compatibility & Scalability

• Interoperability:

• Works with Cisco CRS, ASR, and NCS router families.

• Supports third-party transponders (Infinera, Ciena) via OTN standards.

• Expansion:

• Modular design supports up to 96×100G ports with high-density line cards.

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

9. Software Ecosystem

• Operating System:

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

• Regular updates (e.g., Release 7.1 introduces IPv6-over-OTN support).

• Lifecycle Support:

• End-of-Sale (EOS): Announced for 2026 (check Cisco lifecycle tracker).

• Extended Support: Available via Cisco SMARTnet contracts.

10. 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.
