DWDM-SFP-61.42 — 1561.42 nm — SFP 1 Gbps

The Cisco DWDM-SFP-61.42 is a 1 Gbps SFP module for single-mode fiber (SMF), operating at the DWDM wavelength of 1561.42 nm with a reach of 80 km. Fitted with an LC (UPC) duplex connector and IEEE 1000BASE-X compliant, it operates from 0 to 70 degrees C for use in standard datacenter environments.

This module represents the 1 Gbps version of the 1561.42 nm channel, ideal for Gigabit links on DWDM infrastructure where spectral precision is essential. It integrates into SFP-compatible Cisco switches and routers, enabling operators to add DWDM channels without replacing the optical infrastructure. Genuine Cisco hardware, manufacturer warranty.
