Fraunhofer HHI develops distributed aggregation and reception of 400 Gb/s

By Matthew Peach

“Record-breaking” superchannel in a single-photodiode 110-GHz Kramers-Kronig receiver. Berlin’s Fraunhofer Heinrich Hertz Institute HHI has developed a distributed superchannel aggregation scheme to demonstrate ultra-wideband single-photodiode reception based on inherently polarization-aligned Kramers-Kronig carrier generation at the receiver. For optimized conditions, a record net capacity of 400 Gb/s was achieved using a distributedly aggregated superchannel of 3×33 […]
