Cisco 10GBASE-DWDM SFP10G 1560.61 nm 100-GHz ITU Grid | DWDM SFP — CON-SSSNT-DW0G4851

Move 10 GbE traffic across DWDM fiber infrastructure with a transceiver aligned to the 100-GHz ITU grid. The 1560.61 nm wavelength supports dense channel planning, making it a practical fit for networks where fiber capacity must be conserved and wavelengths must stay tightly managed. This class of SFP is built for environments that already operate DWDM optics and need precise wavelength placement rather than generic short-reach connectivity. It is well suited to metro aggregation, campus backbone links, and transport segments where multiple services share the same fiber plant. By using a compact SFP footprint, it preserves port density while supporting high-value optical deployments. Choose this module when link planning, spectral efficiency, and compatibility with DWDM infrastructure matter more than commodity optics. It is the right kind of part for teams standardizing on controlled optical channels and long-lived backbone design.
