QSFP-100GBASE-CWDM Use Case
Hyperscale Data Center Interconnect with QSFP-100GBASE-CWDM-QSFP28, 100GBASE-CWDM4
A global cloud provider deploys QSFP-100GBASE-CWDM-QSFP28 (100GBASE-CWDM4) modules over existing single-mode fiber to interconnect multi-rack pods across 2 km spans. By leveraging four CWDM wavelengths on a duplex link, the operator reduces fiber infrastructure costs by 75%, achieves line-rate 100Gbps throughput, and simplifies port density in its spine-leaf topology. The outcome is a future-proof, low-power interconnect that scales to petabit-class fabrics while meeting SLAs for high availability and predictable latency.
Enterprise Campus Metro Ethernet Aggregation Using 100GBASE-CWDM4 Transceivers
A regional service provider implements QSFP-100GBASE-CWDM-QSFP28 (100GBASE-CWDM4) at its metro aggregation sites to deliver 100Gbps Ethernet services to multiple enterprise campuses within a 10 km ring. The CWDM4 transceivers enable four independent wavelengths on a single duplex fiber, cutting fiber leases and OPEX by 60%. Customers benefit from guaranteed bandwidth, simplified network management with pluggable optics, and power savings of up to 2W per port, ensuring competitive SLAs and rapid service turn-up.
High-Density Spine-Leaf Deployment in Cloud Service Provider Networks
A Tier-1 cloud provider upgrades its spine-leaf fabric with QSFP-100GBASE-CWDM-QSFP28, 100GBASE-CWDM4 optics to connect 48-port leaf switches to high-capacity spine nodes over 1–2 km fiber runs. The CWDM4 modules deliver 100Gbps per port while preserving existing fiber assets and minimizing heat dissipation in congested racks. This results in a 40% increase in port density, a 25% reduction in power and cooling costs, and streamlined operations through hot-swappable, vendor-neutral optics compatible with major switch platforms.
