Cisco SNTC-8X5XNBD 10GBASE-DWDM SFP10G 1539.77 nm | DWDM, SFP+ — CON-SNT-DW0G3977

Preserve 10 GbE connectivity across wavelength-sensitive fiber infrastructure with Cisco SFP10G DWDM optics tuned to 1539.77 nm. This transceiver is built for networks that depend on disciplined optical planning, where channel placement, link stability, and vendor-aligned compatibility are essential to keeping transport layers predictable. For enterprise teams extending service across metro or campus fiber, DWDM optics help maximize existing plant investment without changing the physical path. The 10GBASE-DWDM design supports high-density transport strategies that favor controlled wavelength assignment over generic short-reach optics. That makes it a strong fit for environments where uptime, optical budget, and network consistency carry real operational value. Cisco optics are often selected when the cost of a failed link is far greater than the cost of the module itself. This part is suited to teams standardizing on Cisco infrastructure and looking for a transceiver that aligns with established deployment practices. If your network depends on precise optical behavior and long-distance 10 GbE transport, this module belongs in the design.
