SIB-I-T4000 Use Case
Hyperscale Cloud Data Center Spine-Leaf Aggregation
A global cloud provider deploys the SIB-I-T4000-Switch Interface Board in T4000 leaf switches to deliver 240G per slot uplinks into a 64-node spine fabric. This high-density, low-latency architecture boosts east-west throughput by 35%, simplifies port consolidation and accelerates VM migrations—driving up time-to-market for new services.
5G Mobile Core and Edge Compute Acceleration
A Tier-1 telecom operator integrates the SIB-I-T4000 in its T4000 routers at regional PoPs to support vRAN and mobile core functions with 240G per slot performance. The uniform high-bandwidth fabric reduces packet-processing delays by 40% and enables real-time network slicing, ensuring SLA-grade QoS for enterprise IoT and AR/VR applications.
Ultra-Low-Latency Financial Trading Network
A multinational investment firm leverages the SIB-I-T4000 in T4000 switches across its trading floors to achieve 240G per slot connectivity between matching engines and market data feeds. By halving serialization delays and ensuring deterministic throughput, the solution slashes round-trip latency to sub-50 µs, maximizing order execution speed and competitive edge.
