A global service provider integrates the SPA-4XOC48POS/RPR-4-port OC48/STM16 POS/RPR Shared Port Adapter into its core Cisco router fleet to aggregate four independent OC48/STM16 links over a single chassis slot. By dynamically allocating ports between POS and RPR, the operator increases link utilization by 30%, delivers up to 19.9 Gbps per port and achieves N+1 resiliency. Outcome: higher revenue per fiber, simplified operations and sub-50 ms failover to meet demanding SLAs.
A metropolitan utility deploys multiple SPA-4XOC48POS/RPR adapters on Cisco aggregation switches to build a resilient packet ring across 16 downtown nodes. Leveraging RPR’s distributed fairness and sub-100 ms protection switching, the smart-grid network sustains guaranteed throughput for video surveillance and IoT telemetry. Outcome: deterministic performance, 40% lower CAPEX by reusing existing fiber, and rapid fault isolation to maintain 24/7 public services.
A financial exchange uses the SPA-4XOC48POS/RPR on high-performance routers to connect multiple data centers over dedicated OC48/STM16 trunks. Hardware-accelerated forwarding with sub-200 μs port-to-port latency and selective POS header compression ensures minimal jitter. Outcome: sub-2 μs latency variance, robust ring protection for continuous market data flow and a 25% reduction in lease costs by consolidating four physical ports into one adapter.
