Ethernet Alliance points to 800GbE, 1.6TbE future
standards exist for 2.5Gb/s, 5Gb/s, 25Gb/s, 40Gb/s, 50Gb/s, 100Gb/s, 200Gb/s, and 400Gb/s.
The latter is currently where Ethernet hits its limit, but the Ethernet Alliance - a consortium of companies currently responsible for developing the eponymous networking standard - is preparing 800GbE, which as the name implies offers 800Gb/s throughput, while suggesting that 1.6TbE could launch alongside it or shortly after.
'Ethernet is bursting through speed barriers at a breakneck pace. With higher speeds and longer reaches, it’s now pushing past its history as an innovative consumer technology into diverse new markets and application spaces like enterprise storage, automotive, and building automation,' claims Greg McSorley, president of the Ethernet Alliance, following the development of demonstrations scheduled for the European Conference on Optical Communications (ECOC 2019) later this month. 'The 400GbE era is here but it’s only a stepping stone along the road to 800GbE. The secret to Ethernet’s continued success has always been and will continue to be interoperability. Getting traffic to travel seamlessly from today’s legacy implementations into tomorrow’s high-speed switches and ecosystems comes down to preserving Ethernet’s capacity for multi-vendor interoperability, which is highlighted in our ECOC 2019 demo.'
The Alliance, however, is somewhat quiet on exactly when the 800GbE and 1.6TbE standards are likely to be ratified: The public roadmap has them pushed projected for around 2022 or later - though only as 'possible future speed' rather than a fully-confirmed theoretical throughput limit - which has been its target since unveiling its plans back in March 2018.

Ok, so only LWLG can get to 400Gbs with 4 lanes NRZ OOK, this is the ONLY cheap, simple solution to 400Gbs, all of the other Legacy technologies can get there by using PAM4 and 50Gbs devices, but only LWLG can deliver 100Gbs devices that can achieve 400Gbs transmissions WITHOUT complex, expensive modulation formats
LWLG is currently in FINAL optimizations of a 100Gb PkM Gen2 2.5V device which is TWICE the speed and HALF the power of all the Legacies! LWLG will soon be unveiling this device with Power reduced to sub-1V and this is truly the holy grail of Photonics as it will eliminate the need for a power hungry "Driver" for the modulator to function, instead LWLG's device being so low voltage it will power directly from the CMOS itself without a driver!
when you get to 800Gbs it gets even tougher for the Legacies, they would now need to increase to 8 lanes at their max speed 50Gbs and use PAM4, with LWLG you could still stay at 4 lanes with 100Gbs devices but require PAM4, however LWLG has already demonstrated device speeds as high as 130GHz which translates to 150Gbs standalone device speeds, so investors know that already an optimized version of the 150Gbs device would support 600Gbs NRZ, simple and cheap, but investors also already know that LWLG's technology has PROVEN femtosecond response times which in theory means LWLG's technology can get to 1Tb standalone speeds (that's 1,000Gb!) meaning that it is possible to extend LWLG's simple and cheap NRZ OOK to support 4Tb (4,000Gb) transmissions using 4 lanes running at 1Tb NRZ OOK, this is simply off the charts incredible!
