In hyperscale data centers, integrating the DES-85-4TE-SFP+-MPLSE board into spine switches aggregates four 10 GbE fibre links with hardware-accelerated MPLS-E forwarding. This delivers sub-microsecond latency, non-blocking throughput and deterministic QoS across virtualized workloads, reducing east-west bottlenecks by 60% and supporting rapid VM migrations with carrier-grade reliability.
Large enterprises deploy the 4-port 10 Gigabit SFP+ enhanced board in core campus distribution to segment voice, video and data VLANs over a single fibre ring. Built-in MPLS-E guarantees traffic isolation, streamlined provisioning and fast-fail protection in under 50 ms. The result is a 40% reduction in operational complexity, predictable SLA compliance and scalable bandwidth growth up to 40 Gbps per uplink.
Service providers use the DES-85-4TE-SFP+-MPLSE board in aggregation routers to deliver point-to-multipoint metro Ethernet services. Four independent 10 Gbps SFP+ ports with MPLS-E label stacking enable flexible bandwidth profiles, per-customer SLAs and automated service chaining. Outcomes include 99.999% network availability, 50% faster service turn-up and a 25% increase in average revenue per user (ARPU).
