Cisco 10GBASE-DWDM SFP+ 1538.98 nm Remanufactured | DWDM, Enterprise — DWDMSFP10G38.98-RF

Keep 10 GbE traffic moving across DWDM infrastructure with a Cisco SFP+ transceiver built for wavelength-specific transport. Tuned to 1538.98 nm, this remanufactured module is suited for environments where optical planning, channel alignment, and predictable link behavior are non-negotiable. For teams extending service across metro, campus, or aggregation layers, DWDM optics help preserve fiber capacity without adding new strands. This module fits the procurement profile of infrastructure teams that need Cisco compatibility and a lower-cost path than new-in-box optics, while still maintaining the operational discipline required in production networks. Because it is built to order and remanufactured, it is a practical choice for sustaining installed Cisco environments, supporting refresh projects, and replacing failed optics in wavelength-managed networks. Use it where the design calls for 10 GbE over DWDM and where the value of the optic is measured in uptime, compatibility, and network continuity—not just port speed. Ideal For Metro aggregation links on wavelength-managed fiber plants Campus backbone extensions where fiber strands are constrained Cisco refresh programs requiring compatible replacement optics Production spare pools for DWDM-enabled 10 GbE networks Why This Product 1 DWDM wavelength-specific design for controlled optical planning 2 Remanufactured format for lower acquisition cost than new optics 3 Cisco compatibility for installed-base replacement workflows 4 10 GbE SFP+ transport for dense fiber environments
