ON2020 rallies industry to address networking concerns
Thursday, November 23, 2017 at 7:58AM Peter Winzer highlights one particular slide, part of the operator-findings presentation, to explain the purpose of the Optical Networks 2020 (ON2020) group.

The slide shows how router-blade client interfaces are scaling at 40% annually compared to the 20% growth rate of general single-wavelength interfaces (see chart).
Extrapolating the trend to 2024, router blades will support 20 terabits while client interfaces will only be at one terabit. Each blade will thus require 20 one-terabit Ethernet interfaces. “That is science fiction if you go off today’s technology,” says Winzer, director of optical transmission subsystems research at Nokia Bell Labs and a member of the ON2020 steering committee.
This is where ON2020 comes in, he says, to flag up such disparities and focus industry efforts so they are addressed.
