HSD1-400-ZR-DMS is intended to be used in conjunction with a host platform to support 400G

transmission over optical links in DCI applications. 400ZR is identified for use in the

following applications. Three use cases of amplified point-to-point links are identified for

400ZR. For amplified links, the reach is dependent on the OSNR (noise limited) at the receiver.

The 400ZR targeted reach for these applications is 80–120 km or longer.

The following figure shows the example of an unamplified link, where the transmission distance depends on the transmit output power, input receiver sensitivity, and channel loss.
