DWDM-X2-31.90 — Cisco SFP

The DWDM-X2-31.90 is a Cisco X2 format optical module for DWDM deployments on single-mode fiber. It is assigned to a channel of the DWDM grid whose exact wavelength is not listed in the available specifications. The X2 form factor, distinct from SFP+, is required by certain Cisco router and switch product lines for 10G optical interfaces.

Suited to long-haul network architectures requiring native X2 compatibility, this transceiver simplifies integration into existing Cisco infrastructures without hardware replacement. It is well suited to NOC teams and integrators managing high-availability backbone links. A reliable reference for extending DWDM transport capacity. Genuine hardware, manufacturer warranty.
