DWDM-SFP-4612 Use Case
Tier-1 ISP Backbone Capacity Upgrade
In a tier-1 internet service provider backbone upgrade, network engineers deploy the DWDM-SFP-4612 1546.12 nm SFP 100G module on their C-band ITU grid to run 100G lanes over existing dark fiber. Outcome: doubles per-fiber throughput with sub-10 µs latency, slashes OPEX by re-using legacy infrastructure, and accelerates capacity expansion.
Hyperscale Data Center Interconnect (DCI)
A global cloud service provider uses DWDM-SFP-4612 1546.12 nm 100G transceivers to link two hyperscale data centers across an 80 km metro DWDM ITU grid. Outcome: delivers plug-and-play 100G connectivity without extra multiplexers, enabling on-demand bandwidth scaling, reduced power consumption, and rapid time-to-market for new services.
5G Edge Fronthaul and Midhaul Transport
A mobile network operator deploys DWDM-SFP-4612 1546.12 nm SFP 100G modules in edge PoPs to aggregate 5G fronthaul and midhaul traffic over an existing DWDM ITU grid. Outcome: ensures ultra-low latency (<50 µs) and high-capacity transport, simplifies network management, and future-proofs the network for 5G and beyond.
