400Gbps data transmission achieved over DCI in a 75 GHz DWDM channel

NeoPhotonics has completed experimental verification of the transmission of 400Gbps data over data center interconnect (DCI) ZR distances in a 75 GHz spaced Dense Wavelength Division Multiplexing (DWDM) channel. NeoPhotonics achieved two milestones using its interoperable pluggable 400ZR coherent modules and its specially designed athermal arrayed waveguide grating (AWG) multiplexers (MUX) and de-multiplexers (DMUX). First, ...
