Cisco DWDMSFP10G58.17-RF 10GBASE-DWDM 1558.17 nm | SFP+ Module — DWDMSFP10G58.17-RF

Support high-density optical transport with a Cisco SFP+ transceiver tuned to 1558.17 nm and 100 GHz ITU grid spacing. This module is built for 10GBASE-DWDM networks that depend on exact wavelength placement to keep channels separated, predictable, and easy to manage across metro, campus, and backbone links. For teams maintaining installed Cisco infrastructure, the remanufactured format offers a practical path to replacement or expansion without changing the optical design. It is a strong fit when the network already runs on fixed DWDM wavelengths and the priority is to preserve compatibility, control cost, and avoid unnecessary redesign. Use it where fiber is scarce, channel plans are fixed, and transport needs to stay disciplined. The result is a replacement optic that matches the operational requirements of dense DWDM systems while keeping procurement more efficient than buying new hardware for every port. Ideal For Replacing a Cisco DWDM optic in a live 10 GbE transport circuit Supporting a fixed-channel metro DWDM deployment Extending fiber-efficient interconnects between data center sites Maintaining wavelength consistency in an existing optical backbone Why This Product 1 1558.17 nm wavelength for fixed DWDM channel assignment 2 100 GHz ITU grid support for dense optical transport 3 Cisco compatibility for established network environments 4 Remanufactured option for lower procurement cost
