    Overview

    Cisco DWDM-SFP-4056 Overview

    The Cisco DWDM-SFP-4056 is a carrier-grade DWDM SFP transceiver designed for dense wavelength-division multiplexing on the 100 GHz ITU grid. Operating at a precise 1540.56 nm wavelength, this hot-pluggable optical transceiver simplifies sparing and field replacement for distributors and system integrators across Asia, Europe, Africa, and North America. The DWDM SFP-4056 enables high-capacity, long-reach optical links in enterprise and service provider transport networks while maintaining efficient use of existing fiber infrastructure.
