A large university deploys the D-Link DES-85-48GE-SFP-MPLS-L 48-port Gigabit Optical Service Board in its core switches to aggregate fiber runs from 20 buildings across a 15 km campus. Leveraging SFP-based gigabit links and MPLS-LITE segmentation, IT delivers low-latency access to 12 000 students and staff while simplifying cable management and supporting future 10 Gbps uplinks. Outcome: consolidated network fabric, 30% reduction in link failures, and scalable performance growth.
A financial services firm integrates the DES-85-48GE-SFP-MPLS-L board into its leaf switches to connect 48 server racks via SFP optics and aggregate traffic to spine switches with redundant 10 Gbps uplinks. The board’s high port density and hardware-assisted MPLS enable predictable East-West throughput and sub-millisecond latency for latency-sensitive trading applications. Outcome: 40% lower oversubscription ratio, sub-1 ms latency SLAs, and streamlined fiber deployment.
An ISP installs the D-Link 48-port Gigabit Optical Service Board in its central office routers to terminate customer fiber circuits with SFP modules and apply MPLS VPN for secure multi-tenant services. Advanced QoS and traffic-engineering features ensure SLA compliance for up to 48 small business customers. Outcome: 25% increase in port utilization, automated provisioning via SNMP, and guaranteed 99.99% uptime.
