800G Ethernet specification

The 25 Gigabit Ethernet Consortium has decided to ditch its name as it heads off in search of serious speed with 800G specification.

To mark the new name, the group has published 800G specification [PDF] that details its next step in Ethernet’s evolution.

25 Gigabit Ethernet Consortium Rebrands to Ethernet Technology Consortium; Announces 800 Gigabit Ethernet (GbE) Specification

800G specification

This specification is based on reusing two 400G PCS/FEC blocks to handle 800G traffic (32x25Gb/s). On low level physical interface the architecture could support 8×106.15G or 16×53.125G serial interfaces. 800G will use either C2M or C2C interface to 800G module (emerging IEEE 802.3ck standard).

Here is block diagram from specification:

    Rambus has released security for 800 Gigbit Ethernet MAC (media access control) for enhanced data center and 5G infrastructure. It secures data that moves from point to point throughout a network, protecting it from denial of service, intrusion, man-in-the-middle, passive eavesdropping, and masquerading attacks, according to a press release. The 800G MACsec is compliant with IEEE 802.1ae MACsec standard.
