A global enterprise deploys build-to-order DWDM-SFP-4056 (1540.56 nm) modules over 80 km of dark fiber to link two data centers at 100 Gbps per wavelength. Benefit: achieves a 40% increase in bandwidth utilization, cuts latency below 500 µs, and delivers scalable, pay-as-you-grow capacity without new fiber builds.
A regional Internet service provider integrates DWDM-SFP-4056 (1540.56 nm) modules on its metro ring to add twenty 100 Gbps channels over existing fiber. Benefit: boosts total capacity by 2 Tbps in under one hour, lowers OPEX by 25%, and enables rapid enterprise service roll-outs without trenching.
A mobile operator installs DWDM-SFP-4056 (1540.56 nm) modules to aggregate 5G fronthaul/backhaul traffic across 50 km of metro fiber. Benefit: consolidates multiple 10/25 Gbps streams into a single 100 Gbps wavelength, maintains sub-1 ms transport latency, and supports network slicing with carrier-grade reliability.
