Demystifying DWDM for the DCI
In previous articles, we discussed how using passive Dense Wave Division Multiplexing (DWDM) can help network operators achieve very high per-fiber capacity using inexpensive passive DWDM filters in 40 channel or even 80 channel variants.
Using these filters and putting 10Gbps circuits on each channel can push the data rate per-fiber connection in excess of 400Gbps without the expensive (and often hard-to-get) network switches.
