Fiber Nonlinearity Mitigation by Short-Length Probabilistic Constellation Shaping for Pilot-Aided Signaling
Tobias Fehenberger, Helmut Griesser, Jörg-Peter Elbers
Probabilistic constellation shaping (PCS) offers a significant performance improvement over uniform signaling. It was recently discovered that long blocks are not required to achie…
56 Gb/s DMT Transmission with VCSELs in 1.5 um Wavelength Range over up to 12 km for DWDM Intra-Data Center Connects
Annika Dochhan, Nicklas Eiselt, Robert Hohenleitner +7
We demonstrate up to 12 km, 56 Gb/s DMT transmission using high-speed VCSELs in the 1.5 um wavelength range for future 400Gb/s intra-data center connects, enabled by vestigial side…
Solutions for 400 Gbit/s Inter Data Center WDM Transmission
Annika Dochhan, Nicklas Eiselt, Helmut Grießer +4
We review some currently discussed solutions for 400 Gbit/s inter-data center WDM transmission for up to 100 km. We focus on direct detected solutions, namely PAM4 and DMT, and pre…
Optimizing Discrete Multi-tone Transmission for 400G Data Center Interconnects
Annika Dochhan, Helmut Griesser, Nicklas Eiselt +2
Discrete multi-tone transmission (DMT) is a promising candidate for future 400G data center interconnects. Eight channels, each carrying 56 Gb/s of data can be combined in a 50-GHz…
Practical Solutions for 400 Gbit/s Data Center Transmission
Annika Dochhan, Nicklas Eiselt, Jinlong Wei +5
We review three solutions for low-cost data center interconnects with a target reach of up to 80 km. Directly detected DMT, PAM-4 and multi-band CAP are promising modulation scheme…
Solutions for 80 km DWDM Systems
Annika Dochhan, Helmut Griesser, Michael Eiselt +1
We review currently discussed solutions for 80 km DWDM transmission targeting inter data-center connections at 100G and 400G line rates. PDM-64QAM, PAM4 and DMT are investigated, w…
