The Cisco ASR 9903 2T Multirate Port Expansion Card is a high-performance carrier-grade line card designed for the Cisco ASR 9903 modular routing platform. Built to deliver up to 2 terabits of forwarding capacity, this expansion module enables service providers, cloud operators, and large enterprises to scale network bandwidth efficiently without replacing core routing infrastructure.

Engineered for modern high-speed networks, the card supports a flexible mix of interface speeds including 10G, 25G, 40G, 100G, 200G, and 400G Ethernet, allowing seamless integration into evolving network environments. With a combination of QSFP-DD and QSFP28 ports, the module provides maximum flexibility for mixed-speed deployments, making it ideal for backbone routing, metro aggregation, data center interconnect (DCI), and Internet peering applications.

Designed for scalability and long-term investment protection, the ASR 9903 2T card allows operators to gradually increase network capacity while maintaining compatibility with existing optical and Ethernet infrastructure. This reduces operational complexity and helps optimize capital expenditure across large-scale deployments.

The module is built for mission-critical environments where performance, reliability, and uptime are essential. It is commonly deployed in service provider core networks, cloud edge infrastructure, and high-capacity transport networks, where consistent low-latency performance and high throughput are required.
