Cisco Compatible DWDM-SFP+-XXXX-40 | 10G DWDM SFP+ LC SMF 40km (C-Band)

Cisco Compatible DWDM-SFP+-XXXX-40 10GBASE-DWDM SFP+ Optical Transceiver (LC Duplex, C-Band, 40km)

Product Overview

The Cisco compatible DWDM-SFP+-XXXX-40 optical transceiver is a high-performance 10Gbps module designed for Dense Wavelength Division Multiplexing (DWDM) applications over single-mode fiber (SMF). Operating on the ITU-T DWDM grid (C-Band), it enables multiple high-density optical channels over a single fiber pair, dramatically increasing bandwidth capacity without additional fiber deployment.

With a reach of up to 40 kilometers, this SFP+ module is ideal for metro networks, telecom aggregation, and data center interconnect (DCI) scenarios requiring scalable, high-capacity transmission.

“XXXX” represents the DWDM channel (e.g., CH17–CH61) or corresponding ITU frequency (e.g., 191.7THz–196.1THz).
