Group Delay Measurements of Multicore Fibers with Correlation Optical Time Domain Reflectometry
Florian Azendorf, Annika Dochhan, Florian Spinty +3
Several multi-core fibers (MCF) were characterized using Correlation Optical Time Domain Reflectometry (C-OTDR) in terms of propagation delay and polarization mode dispersion (PMD)…
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…
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…
Flexible bandwidth 448 Gb/s DMT Transmission for Next Generation Data Center Inter-Connects
Annika Dochhan, Helmut Grießer, Michael Eiselt +1
We experimentally evaluate a flexible DMT system using 4 to 8 50-GHz-grid C-band channels to transmit 448 Gb/s over up to 240 km SSMF. VSB filtering enabled by detuned lasers signi…
Experimental Investigation of Discrete Multitone Transmission in the Presence of Optical Noise and Chromatic Dispersion
Annika Dochhan, Laia Nadal, Helmut Griesser +3
Enabled by channel adaptive bit and power loading, we experimentally demonstrate discrete multitone transmission at 56Gb/s with simple intensity modulation and direct detection and…
