PTX10K-LC1102 Use Case
High-Throughput Data Center Interconnect for Hyperscale Cloud Environments
A global cloud provider deploys the PTX10K-LC1102-PTX10K 1.44T Line Card – 36X40G/12X100G (JNP10K-LC1102) in its spine layer to aggregate east-west traffic between multiple availability zones. Leveraging 12×100 GbE for cross-pod replication and 36×40 GbE for intra-pod distribution, the solution delivers sub-100 µs latency and 1.44 Tbps aggregate throughput. The outcome is seamless VM migration, accelerated data backups, and predictable SLAs at scale.
Scalable IP/MPLS Core Backbone for Tier-1 Service Providers
A Tier-1 telecom operator integrates the PTX10K-LC1102-PTX10K 1.44T Line Card – 36X40G/12X100G (JNP10K-LC1102) into its IP/MPLS core to converge mobile backhaul, fixed broadband, and enterprise VPN services. By terminating 12×100 GbE links to regional POPs and 36×40 GbE to metro edge routers, the operator achieves 1.44 Tbps switching capacity with deterministic traffic engineering. The result is simplified network design, reduced line-card count, and guaranteed 5-9s availability for premium SLAs.
Ultra-Low-Latency 5G Transport and Network Slicing
A 5G network integrator deploys the PTX10K-LC1102-PTX10K 1.44T Line Card – 36X40G/12X100G (JNP10K-LC1102) at aggregation nodes to support packet core and fronthaul clusters. Utilizing 36×40 GbE for RAN fronthaul and 12×100 GbE for core connectivity with programmable forwarding, the platform delivers sub-200 µs end-to-end latency and dynamic bandwidth allocation per slice. The benefit is high-performance network slicing, future-proof capacity scaling, and assured QoS for ultra-reliable, low-latency applications.
