Description

The Cisco NCS2K-400GXP-L-K9 is a high-performance optical transponder designed for dense wavelength-division multiplexing (DWDM) networks within the Cisco NCS 2000 Series. Engineered to support up to 400 Gbps line rates, this module enables efficient transport of high-bandwidth services across metro and long-haul optical infrastructures. Its compact, plug-in design allows for seamless integration into existing NCS 2000 chassis, making it a cost-effective upgrade path for expanding network capacity. The unit supports advanced modulation formats, including QPSK and 16-QAM, to optimize spectral efficiency and reach.

Key features include support for coherent detection, forward error correction (FEC), and flexible grid compatibility, enabling dynamic bandwidth provisioning and reduced operational overhead. The 400GXP-L-K9 includes dual QSFP-DD client interfaces and is built for high-density deployments, supporting multiple 100GE or 400GE services per module. It also integrates with Cisco’s software-defined networking (SDN) platforms, offering centralized control and real-time performance monitoring. This used model is ideal for service providers and enterprises seeking reliable, scalable transport solutions without the premium cost of new hardware.
