DWDM-SFP10G-40.56 — Cisco SFP+ 10G

The DWDM-SFP10G-40.56 is a Cisco SFP+ 10G transceiver for DWDM architectures over single-mode fibre. Sharing the 40.56 spectral position in SFP+ form factor, this module operates on a dedicated ITU-T grid channel; no value in nm is disclosed in the current specifications. Its 10G throughput positions it on high-bandwidth transport links.

Suited to core networks and inter-site interconnects, this Cisco SFP+ 10G module integrates natively with compatible Cisco routers and switches. The reference DWDM-SFP10G-40.56 clearly distinguishes it from the SFP model at the same spectral position, preventing ordering errors. Genuine Cisco hardware, manufacturer warranty.
