Guest Blog400G is now under release over multiple form-factors: QSDFP-DD, OSFP and CFP8. While the short-term deployment is on the access side, and mainly for intra-DC application, other applications such as DCI and transmission are also going on the 400G direction. As we are now getting familiar with the form-factors and the PAM4 modulation, it is […]

Applications and ResearchAcacia Communications has announced the first 400G single carrier DWDM transmission on the 6,600 km Marea submarine cable between Virginia Beach, USA, and Bilbao, Spain. The field demonstration was conducted by Acacia in collaboration with Microsoft and Facebook, and helped to demonstrate that improvements in capacity and spectral efficiency can enable increased utilisation of deployed […]
Applications and Research“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 […]
