DWDM-SFP-3112= Use Case
High-Capacity Data Center Interconnect Over Long-Haul Fiber
A cloud service provider deploys the DWDM-SFP-3112 1531.12 nm SFP 100 GHz ITU-grid transceiver to link two hyperscale data centers 80 km apart on existing single-mode fiber. Leveraging precise channel spacing and 100 Gbps transmission, this solution delivers 4× bandwidth expansion, 25% lower OPEX, and carrier-grade signal integrity, ensuring low-latency, error-free replication and seamless plug-and-play integration with industry-standard switches.
Metro Core Network Upgrade for Telecom Carrier
A national telecom operator integrates the DWDM-SFP-3112 1531.12 nm SFP 100 GHz ITU-grid module across its metro core routers to multiply wavelength channels on legacy fiber rings. With scalable 100 GHz spacing, channel count jumps from 8 to 24 per fiber pair, boosting aggregate capacity by 200%, simplifying SFP-based inventory, and ensuring multi-vendor interoperability—driving higher revenue per fiber and agile service delivery.
Ultra-Low-Latency Financial Trading Network Link
A financial trading firm installs the DWDM-SFP-3112 1531.12 nm SFP 100 GHz ITU-grid transceiver on its exchange connectivity path to minimize latency between the trading platform and primary data center. Optimized dispersion compensation and high optical signal-to-noise ratio achieve sub-microsecond transmission over 40 km fiber, enabling faster trade execution, SLA compliance for latency-sensitive applications, and seamless future scaling to 100 GbE.
