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.
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.
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.

DWDM SFP 1531.12nm ensures stable long-distance performance and minimal errors.
Professional-grade optics for metro and enterprise DWDM deployments.
Durable module, easy integration, consistent throughput.
Reliable performance under full network load.
Ideal choice for critical backbone optical links.
The DWDM-SFP-3112= operates at 1531.12 nm on the ITU-grid with 100 GHz channel spacing for precise dense wavelength division multiplexing.
Over standard single-mode fiber (SMF), the module supports up to 80 km reach without dispersion compensation in a well-managed optical link.
This DWDM SFP is hot-pluggable and interoperable with any 100 GHz-compliant SFP port, including major brands like Cisco, Juniper, Arista and Huawei.
Power down the device, insert the SFP module into the empty SFP slot until it clicks, reconnect fiber and power on—no driver installation is required.
