Cisco Network Convergence System 4000 Series Optical Transport Network/Packet Line Card – expansion module – 10 Gigabit SFP+ x 10 + 100 Gigabit CPAK x 2

The NCS 4000 multilayer converged line card provides the ability to deploy OTN packets at 10 Gbps and 100 Gbps rates using an agnostic switch fabric to switch up to 200 Gbps I/O capacity. OTN provides robust transport services that use many of the benefits of SONET / SDH such as resiliency and performance monitoring, while adding enhanced multirate capabilities in support of packet traffic, plus the transparency required by DWDM networks. OTN is the ideal technology to bridge the gap between advanced IP and legacy time-division multiplexing (TDM) networks by acting as a converged transport layer for packet-based and existing TDM services.
