DWDM-XFP-42.94-RF — Cisco SFP

The DWDM-XFP-42.94-RF is a Cisco XFP Remanufactured (RF) transceiver for DWDM links over single-mode fiber. The SKU clearly distinguishes this module from non-RF variants in the same series; no precise wavelength is specified in the available documentation, with the channel defined by the Cisco product reference.

The RF status makes it a cost-effective solution for operators looking to maintain or expand an existing DWDM XFP infrastructure while retaining Cisco quality assurance. Suited for long-haul backbones and inter-node links. Cisco Remanufactured module, manufacturer warranty.
