Ethernet is not dead: up to 400Gbps over fiber


The Ethernet Alliance has revealed at the 2021 Technology Exploration Forum that it is targeting speeds above 400 Gb / s, or 50 GB / s, thanks to a new transmission standard.


It is a proposal for the future, to achieve it the organization assures that it needs to assess the technologies that promise better results towards that objective and if there is a market willing to buy a faster Ethernet.

Currently, the standard that we have in the domestic market focuses on ethernet 6 cables with copper pairs with a maximum speed of 1 Gb / s and in very specific cases we can have devices that reach up to 10 Gb / s. As we can see, we are talking about a theoretical improvement of up to 40x.

The Ethernet Alliance is currently satisfied with the IEEE 802.3cu standard that offers up to 400 Gb / s over single-mode fiber optics, at 100 Gb / s per wavelength. These fibers use less energy in operations and allow cost control and more complex systems to be created, so advancement is important.

Once you’ve completed a standard, keep looking ahead and start thinking about the next one.

Hence, voting began for the IEEE P802.3ck standard that proposes a low-cost interface for 100 Gb / s, 200 Gb / s, and 400 Gb / s Ethernet, reducing reliance on fiber within enterprise environments and domestic.

” This standard, once completed, is intended to enable 100 Gb / s electrical interfaces and support the development of higher density or lower-cost electrical interfaces for 100, 200, or 400 Gb / s Ethernet, ” the organization explained.

This standard will work on fiber optics, achieving connections that can reach a minimum of 80 km with a transfer rate of 100 Gb / s using DWDM (Dense Wavelength Division Multiplexing) systems.

This system enables high-speed connections that can be assembled in a matter of hours, with reduced consumption, and is perfect for supplying information in areas where natural disasters occur or there are any traditional supply problems.
