The Cisco SPA-2XOC48POS/RPR is a dual-port OC-48/STM-16 Packet over SONET/SDH (POS) and Resilient Packet Ring (RPR) Shared Port Adapter, built for high-capacity backbone and metro aggregation networks. Each port delivers 2.488 Gbps full-duplex throughput, providing 4.976 Gbps aggregate capacity with low latency and carrier-grade reliability. The module supports SONET/SDH framing, PPP/HDLC encapsulation, RPR for optimized bandwidth utilization, and rapid protection switching for enhanced network resilience. Ideal for service provider environments, it ensures efficient transport of IP, MPLS, and Layer 2 traffic over optical infrastructure. Fully compatible with Cisco SPA-capable routing platforms, it enables scalable, high-availability deployments for mission-critical applications.
