Description
The Cisco A9903-20HG-PEC is a high-performance 2 Terabit Port Expansion Card (PEC) designed for the Cisco ASR 9903 Compact High-Performance Router. Built to support modern service provider, metro, cloud edge, and Internet peering networks, this expansion module delivers exceptional scalability and flexibility for mass-scale routing deployments.
With a total of 20 physical ports, the card provides a mix of multi-rate 400GE/200GE/100GE QSFP-DD uplinks alongside high-density 100GE QSFP28 connectivity. Operators can seamlessly upgrade select ports to full 400GE capacity through licensing, enabling smooth network evolution as bandwidth demands grow.
The A9903-20HG-PEC is ideal for high-throughput environments requiring carrier-class performance, nonblocking bandwidth, and modular expansion within the ASR 9903 platform.
