A global cloud services operator deploys DWDM-SFP-5979 (1559.79 nm, 100 GHz ITU grid) modules on two data centers 120 km apart. By leveraging ITU-compliant wavelength spacing and DWDM amplification, the operator achieves 100 Gbps full-duplex connectivity over a single fiber pair without regeneration. Benefit: 60% lower OPEX through simplified amplified links, sub-1 ms latency for real-time workloads, and seamless capacity scaling to meet dynamic cloud demand.
A regional telecom provider uses DWDM-SFP-5979 modules to aggregate multiple 10 GbE customer access rings into a 100 GbE DWDM backbone across a 50 km metro fiber loop. The precise 100 GHz channel spacing enables coexistence of legacy and new wavelengths on the same fiber. Benefit: 8× higher port efficiency, 40% reduction in rack space, and rapid service turn-up—driving accelerated revenue from business and residential Ethernet services.
A mobile network operator implements DWDM-SFP-5979 modules in ROADM nodes to backhaul 5G small-cell clusters distributed over a 30–80 km ring. The 1559.79 nm channel provides a dedicated 100 Gbps wavelength per site, ensuring ultra-low jitter and bandwidth reserve for bursty video traffic. Benefit: Guaranteed SLA performance for ultra-reliable low-latency communications, automated wavelength provisioning, and 25% CAPEX savings by reusing existing DWDM infrastructure.
