Cisco NCS2K-R-S1230K9=: Carrier-Grade Routing for High-Density Optical Transport Networks

Overview of the Cisco NCS2K-R-S1230K9= Platform

The ​​Cisco NCS2K-R-S1230K9=​​ is a high-density, modular line card designed for Cisco’s Network Convergence System (NCS) 2000 series, a platform tailored for optical transport networks. As per Cisco’s official documentation, this component supports ​​1230 Gbps of bidirectional throughput​​, making it ideal for service providers and enterprises managing large-scale data traffic. Its primary role is to optimize wavelength-division multiplexing (WDM) networks, enabling seamless scalability for 5G backhaul, cloud interconnect, and video streaming infrastructures.

Technical Specifications and Hardware Design

Cisco’s datasheets highlight the NCS2K-R-S1230K9= as a ​​dual-slot, double-height module​​ compatible with the NCS 2006 and NCS 2015 chassis. Key technical attributes include:

• ​​1230 Gbps aggregate capacity​​ across 12 ports (100G/200G per port).
• Support for ​​flexible grid technology​​, allowing dynamic allocation of spectrum resources.
• ​​Forward Error Correction (FEC) enhancements​​ to reduce signal degradation in long-haul deployments.
• ​​Integrated coherent optics​​ with QSFP28 interfaces for compatibility with third-party transceivers.

Use Cases: Solving Modern Network Challenges

The NCS2K-R-S1230K9= addresses critical pain points in optical transport:

​​1. 5G Backhaul Scalability​​
With 5G networks requiring ultra-low latency and high bandwidth, this line card ensures ​​sub-ms latency​​ and ​​zero service interruption​​ during traffic spikes. A Cisco case study references a European telecom operator that deployed the NCS2K-R-S1230K9= to support 10 million concurrent mobile users.

​​2. Data Center Interconnect (DCI)​​
The module’s ​​200G ZR+ compatibility​​ enables cost-effective, high-capacity links between data centers up to 1,200 km apart.

​​3. Broadcast Video Transport​​
Its ​​hitless tuning feature​​ allows broadcasters to adjust wavelengths without disrupting live video feeds—a requirement for 4K/8K streaming.

Deployment Best Practices and Compatibility

Cisco’s deployment guide emphasizes the following for integrating the NCS2K-R-S1230K9=:

• ​​Chassis Power Requirements​​: A fully loaded NCS 2015 chassis with six NCS2K-R-S1230K9= cards requires 4,200W AC power.
• ​​Thermal Management​​: Operates optimally at ambient temperatures below 40°C, with front-to-back airflow design.
• ​​Software Dependencies​​: Requires Cisco IOS XR Release 7.7.1 or later for advanced telemetry and automation features.

Performance Benchmarks and Reliability Metrics

Independent testing (cited in Cisco’s 2023 whitepaper) reveals:

• ​​99.999% availability​​ in mission-critical scenarios, backed by redundant control processors.
• ​​30% lower power per bit​​ compared to legacy DWDM systems.
• ​​1.5 Tbps encryption throughput​​ using MACsec, ensuring compliance with GDPR and CCPA standards.

Addressing Common Concerns

​​Q: How does the NCS2K-R-S1230K9= handle interoperability with non-Cisco optics?​​
A: The module supports ​​OpenZR+ MSA standards​​, allowing integration with third-party QSFP28 transceivers. However, Cisco recommends using certified optics for warranty coverage.

​​Q: What redundancy options exist for hardware failures?​​
A: The NCS 2000 series supports ​​1:1 card redundancy​​ and Y-cable protection for link failures.

​​Q: Is the hardware future-proofed for 800G upgrades?​​
A: While the current design maxes at 200G per port, Cisco’s roadmap includes ​​software-upgradable DSPs​​ to support 400G/800G via license activation.

Procurement and Licensing Considerations

For organizations evaluating the NCS2K-R-S1230K9=, licensing is tiered based on port activation:

• ​​Base license​​: Unlocks 100G per port.
• ​​Advanced license​​: Enables 200G mode and flexible grid functionality.
