DWDM-SFP-4373-WS — Cisco SFP

The DWDM-SFP-4373-WS is a Cisco SFP optical module designed for DWDM links over single-mode fiber. Its Small Form-factor Pluggable format ensures direct insertion into the SFP slots of compatible Cisco equipment. It is associated with a dedicated channel of the DWDM grid; the wavelength is not mentioned in the available technical data. The WS suffix designates a reconditioned and certified product.

This module is particularly well suited to optical densification projects on existing Cisco platforms, where the goal is to increase transport capacity without investing in new cabling. WS certification ensures compatibility and performance identical to new modules. Cisco-recertified module, manufacturer warranty.
