Low-Complexity Event Detection and Identification in Coherent Correlation OTDR Measurements
Jasper Müller, Ognjen Jovanovic, Florian Azendorf +7
Pairing coherent correlation OTDR with low-complexity analysis methods, we investigate the detection of fast temperature changes and vibrations in optical fibers. A localization ac…
Optimization of Pilot-Aided Joint Phase Recovery for Frequency Comb-Based Wideband Transmission
Gabriele Di Rosa, Ognjen Jovanovic, M. Ahmed Leghari +3
We numerically investigate joint pilot-aided phase recovery for frequency comb-based long-haul wideband transmission. We report net information rate gains by optimizing the pilot o…
Coexistence Options and Performance Analysis of 100 Gbit/s Coherent PON in Brownfield DWDM Networks
Gabriele Di Rosa, Martin Kuipers, Jim Zou +2
We study system architectures for the coexistence of future coherent PON and DWDM networks. Considering deployed optical filters, we observe filtering penalties < 1dB at a laser fr…
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…
