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…
Planning Optical Networks for Unexpected Traffic Growth
Sai Kireet Patri, Achim Autenrieth, Jörg-Peter Elbers +1
A lightpath configuration algorithm considering a multi-period traffic model is presented and evaluated to a realistic German core network study.~Strategically exploiting BVT exces…
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…
