Infinera’s ICE6 sends 800 gigabits over a 950km link

Infinera has demonstrated the coherent transmission of an 800-gigabit signal across a 950km span of an operational network.

Robert ShoreInfinera used its Infinite Capacity Engine 6 (ICE6), comprising an indium-phosphide photonic integrated circuit (PIC) and its FlexCoherent 6 coherent digital signal processor (DSP). 

The ICE6 supports 1.6 terabits of traffic: two channels, each supporting up to 800-gigabit of data. 

The trial, conducted over an unnamed operator’s network in North America, sent the 800-gigabit signal as an alien wavelength over a third-party line-system carrying live traffic.

“We have proved not only the state of our 800-gigabit with ICE6 but also the distances it can achieve,” says Robert Shore, senior vice president of marketing at Infinera.

Infinera prepares for first ICE6 coherent DSP samples

Infinera has taped out its 7nm CMOS FlexCoherent 6 digital signal processor (DSP) and expects samples of the coherent chip in the next fortnight.

“We are ready to start fabricating prototype modules,” says Robert Shore, senior vice president of marketing at Infinera (pictured).

The DSP, along with Infinera’s photonic integrated circuit (PIC) that was demonstrated at the OFC show held in March, will be integrated into a module that supports two wavelengths, each capable of supporting up to 800 gigabits of data. 

The company expects to have a prototype of the 1.6-terabit Infinite Coherent Engine 6 (ICE6) module by year-end, while the first ICE6-based products are scheduled for the second half of 2020.
