CWDM4 trades the cooled lasers of LAN-WDM for uncooled coarse wavelengths, cutting module power and cost for the short reaches that dominate data center interconnect.
Four-channel DOM monitoring reports per-wavelength transmit and receive power, giving operations teams early warning of fiber or connector degradation along the 2km span.
