DWDM-SFP10G-38.19 Use Case
Metro Data Center Interconnect for Cloud Services
A cloud provider deploys DWDM-SFP10G-38.19 (1538.19 nm SFP10G on a 100-GHz ITU grid) over existing dark fiber to link two metro data centers 50 km apart. This module aggregates multi-tenant 10 Gbps traffic on a single fiber, delivering sub-3 ms latency and enabling seamless DCI. Benefit: 40% lower fiber lease costs, scalable channel growth to 80 wavelengths, and consistent 10 Gbps performance under heavy load.
Tier-1 Service Provider Backbone Channel Expansion
A national carrier integrates DWDM-SFP10G-38.19 (1538.19 nm SFP10G, 100-GHz ITU grid) into its OTN DWDM backbone to provision new 10 Gbps circuits over 120 km. By hot-swapping pluggable transceivers on existing mux/demux equipment, the operator achieves carrier-grade SLA activation in under 48 hours. Outcome: 25% reduction in OPEX for wavelength provisioning, 30% faster service turn-up, and guaranteed 10 Gbps throughput with error-free operation.
Enterprise Campus Ring Resiliency and Business Continuity
A global enterprise builds a resilient ring network across 20 sites using DWDM-SFP10G-38.19 (1538.19 nm SFP10G, 100-GHz ITU grid) modules on a dual-fiber CWDM/DWDM hybrid. In a live failover test, traffic reroutes in under 500 ms with zero packet loss. Benefit: 99.999% network availability, sub-second disaster recovery, and simplified plug-and-play management that future-proofs 10 Gbps campus backhaul.
