The Cisco NCS1K14-2.4TX-L2C is a high-performance line card designed for the Cisco Network Convergence System (NCS) 1000 series, targeting service providers and enterprises requiring scalable, low-latency transport solutions. This module supports 2.4 Terabits per second (Tbps) of bidirectional Layer 2 switching capacity, making it ideal for dense wavelength division multiplexing (DWDM) networks, data center interconnect (DCI), and metro aggregation.
Key technical specifications, per Cisco’s official datasheets, include:
The NCS1K14-2.4TX-L2C operates at the optical transport layer, combining DWDM transponders with Layer 2 switching to reduce network layers and operational complexity. Its architecture focuses on three pillars:
A unique feature is its Layer 2 aggregation capability, which allows traffic from multiple client interfaces (e.g., 10G/25G) to be mapped into higher-speed OTU4/OTUCn containers. This minimizes stranded bandwidth and simplifies traffic engineering.
Cisco’s Optical Networking Design Zone highlights three primary scenarios for deploying the NCS1K14-2.4TX-L2C:
Metro Edge to Core Connectivity:
By aggregating traffic from 5G RAN sites or enterprise branches, the module reduces latency to <1 ms per hop, meeting stringent 5G URLLC (Ultra-Reliable Low-Latency Communication) requirements.
Disaster Recovery for Hyperscalers:
Its hitless tunable lasers enable seamless wavelength rerouting between data centers during outages, ensuring zero packet loss during failover events.
Submarine Network Terrestrial Extensions:
The line card’s FEC (Forward Error Correction) algorithms, compliant with OpenZR+ standards, compensate for signal degradation in undersea cable landing stations.
According to Cisco’s NCS 1000 Series Configuration Guide, deploying the NCS1K14-2.4TX-L2C requires:
Chassis Compatibility Checks:
Verify software versions (IOS XR 7.8.1 minimum) and power shelf capacity (3200W per bay) to avoid oversubscription.
Optical Power Budgeting:
Use Cisco’s MCP (Multi-Channel Planner) tool to calculate OSNR (Optical Signal-to-Noise Ratio) for mixed 100G/400G deployments.
Layer 2 Policy Templates:
Define VLAN-to-OTN mappings via Cisco Crosswork Network Controller to automate service provisioning.
For organizations seeking verified hardware, “NCS1K14-2.4TX-L2C=” is available for procurement here.
While the NCS1K14-2.4TX-L2C excels in hybrid Layer 2/OTN environments, IT teams should evaluate:
Having analyzed Cisco’s documentation and real-world deployment logs, the NCS1K14-2.4TX-L2C represents a strategic investment for operators prioritizing scalability without forklift upgrades. Its ability to blend OTN transport with Ethernet flexibility addresses the paradox of rising bandwidth demands and static fiber infrastructure. However, its value is maximized only when paired with Cisco’s ecosystem—Crosswork automation, IOS XR software, and validated optics. For teams navigating cloud-scale transport challenges, this module isn’t just an option; it’s a necessity for future-proofing optical-layer resilience.
