25G CWDM 1490nm LC SFP28 transceiver is a long-reach, high-performance module designed for 40km links over single-mode fiber. It utilizes the 1490nm wavelength in the Coarse Wavelength Division Multiplexing (CWDM) spectrum to provide a single-channel, cost-effective solution for 25G Ethernet. This module is ideal for expanding network capacity and reach in metropolitan area networks (MANs), 5G backhaul, and long-distance data center interconnects, while offering digital diagnostics monitoring (DDM) for enhanced network management.
