Features added around 400ZR aims to bring order to 400ZR+

The OIF has started a project to combine Flexible Ethernet (FlexE) technology with the 400ZR coherent interface standard.

Karl Gass400ZR is designed to transmit a 400 Gigabit Ethernet (GbE) signal over at least 80km using coherent optical transmission.

Adding FlexE technology will enable 4x100GbE signals to also be transmitted.

Separately, the OIF has started a project to create a 96 gigabaud (GBd) coherent driver modulator specification. Such a symbol rate enables 800 gigabits of data to be sent using a single carrier.
