In a global data center, network architects install the EPA-CPAK-2X40GE (requires breakout cable) on Cisco ASR1000 routers to consolidate four 10 GE server connections into two 40 GE uplinks. This high-density 2x40 GE CPAK EPA solution boosts port efficiency by 80%, cuts switch count by half, and reduces operational costs through simplified cabling and improved bandwidth utilization.
A telecom service provider uses the EPA-CPAK-2X40GE spare module on ASR1000 edge routers, paired with a breakout cable, to aggregate multiple 10 GE customer circuits into a single 40 GE link. This approach expands WAN bandwidth capacity by 4× per port, accelerates subscriber onboarding, and drives a 30% increase in service revenue without additional chassis investments.
An enterprise IT group pre-stages an EPA-CPAK-2X40GE spare (with breakout cable) in their ASR1000 rack for disaster recovery. Upon primary link failure, the module is hot-swapped in under 5 minutes, slashing MTTR by 80% and upholding 99.99% SLA compliance for critical cloud and voice applications.
