A national carrier modernizes its regional backbone by deploying DWDM-SFP-3661 modules on existing single-mode fiber to carry 100 Gbps per wavelength over 120 km spans without regeneration. The 1536.61 nm ITU-grid tuning enables seamless coexistence with legacy channels in the C-band. Outcome: doubled capacity, 40% lower OPEX (no new fiber digs), and rapid provisioning of high-bandwidth services to enterprise and wholesale customers.
A financial exchange installs point-to-point 100 G DWDM links between its data center and colocation facility to support algorithmic trading. Using the DWDM-SFP-3661 at 1536.61 nm with ITU grid precision, the network achieves sub-250 µs latency over 50 km of fiber with dispersion compensation. Benefit: milliseconds shaved off round-trip times, enhanced execution speed, and increased competitiveness in high-frequency trading.
A cloud service provider implements multi-site DCI by deploying DWDM-SFP-3661 modules across metro fiber rings to link three data centers. Each 1536.61 nm 100G channel rides over ITU-standardized C-band with low insertion loss and high optical signal-to-noise ratio. Result: scalable bandwidth growth (up to 2.4 Tbps per fiber), simplified operations via pluggable optics, and accelerated service roll-outs for end customers.
